To investigate the photosynthesis and growth of Cymbidium ‘Red Fire’ grown under different nitrogen fertilization and night-interruption (NI) illumination, we exposed plants to 9-h short days (SDs), SDs + 3 - 7 μmol·m-2·s-1 NI (low-light intensity of NI, LNI), or SDs + 120 μmol·m-2·s-1 NI (high-light intensity of NI, HNI) illumination with nitrogen supplemented at 0, 100, 200, or 400 mg·L-1. Cymbidium photosynthesized under 3 – 7 μmol·m-2·s-1 NI regardless of nitrogen treatment, promoting growth. HNI treatments and nitrogen supplements at 100 mg·L-1 increased the leaf chlorophyll concentration. LNI increased net CO2 assimilation (An), transpiration, and stomatal conductance. HNI without supplemental nitrogen reduced midday An. However, HNI with supplemental nitrogen increased midday An. Supplemental nitrogen should be provided to Cymbidium when high-irradiance NI is used to promote growth.

The objective of this study was to identify the main floral scents and their relative contents in the floral organ of Nelumbo nucifera. N. nucifera flower, a traditional Chinese medicinal herb, is rich in volatile compounds. In this study, the volatile components of N. nucifera flowers were investigated by headspace solid-phase microextraction gas chromatography-mass spectrometry for each organ of the flower: petals, sepals, pistils, and stamens. In total, we identified 39 compounds, among which aliphatics were major constituents, representing more than 94% of petals and sepals volatiles, followed by sesquiterpenes representing more than 69% of pistils and stamens volatiles. Pentadecane, 1-pentadecene, 8-hexadecyne, 8-heptadecene, and β-caryophyllene characterize the scent of the N. nucifera flower. We identified 24 volatiles in petals and sepals, 25 volatiles in pistils, and 18 volatiles in stamens. Among the monoterpenes, 3-Isopropylidene-4-methylcyclohexene, isoterpinolene, p-Menth-2-en-7-ol, and methyl 2,6,6- trimethylcyclohex-1-enecarboxylate were analyzed and identified for the first time from the N. nucifera flower. This study demonstrates that N. nucifera flowers differ greatly in volatile composition depending on the floral organ of the plant.

Growth and development of succulents were studied in response to two leaf cutting types, the tip and base, using four Echeveria species (E. ‘A Grimm One’, E. ‘Momorato’, E. pulvinata ‘Frosty’, and E. pulidonis) and the planting position, either upright and faced-downward, using Graptoveria optalina. The shoot diameter (mm), height (mm), and number of leaves were significantly affected by the leaf cutting type. Results revealed that the shoot diameter of buds from base leaves were significantly larger by 4 - 9 times than those of buds from tip leaves. Shoot height of buds from tip leaves either not developed or reached a maximum of 2.29 mm while buds from base leaves had an average height of 11.61 mm from E. ‘Mamorato’. Using base leaves allowed to obtain roots and leaves for all selected succulent species after 60 days from planting. Regarding planting position, upright planted and downward-facing plants showed significant differences: buds from upright planting showed taller shoots, greater number of leaves which in turn gave higher visual quality rating and superior color reading using Hunter’s Cielab compared with buds in downward-facing planting position. Planting succulents in an upright position led to well-formed shoots and roots which had a high-quality rating and color evaluation compared with faced-downward planting producing etiolated and abnormal grown shoots. Based on these findings, we suggest that the use of base leaf cuttings and an upright planting position provides a rapid vegetative propagation method for selected succulent varieties.

A study was conducted to evaluate the effects of auxin, cytokinin, and their combined application to hasten their propagation using leaf cuttings. Different hormone levels were evaluated on two Echeveria species (E. subsessilis and E. runyonii). Three levels of auxin as represented by the use of indole-3-butyric acid (IBA) (0, 100, and 500 ppm), three cytokinin levels as represented by Kinetin (Ki) (0, 100, and 200 ppm) and their combination were applied and observed for 8 weeks. The use of 100 ppm IBA resulted in the highest shoot height, diameter, and rooting and shooting rate. Using 500 ppm IBA led the roots to develop the earliest but both species also had the highest mortality. The application of 100 ppm Ki significantly affected the majority of leaf cuttings of E. runyonnii which exhibited the highest and thickest shoots, and the number of leaves. The application of 100 ppm IBA and 100 ppm Ki is recommended to obtain increased shoot growth and development for leaf cuttings. In the case of single hormone use, the application of 100 ppm IBA may be preferable. The combination of auxin and cytokinin significantly stimulated the hastening of production of succulents using leaf cuttings.

With the purpose of selecting succulents that are capable of retaining their ornamental value under lower light levels of indoor spaces, this experiment was conducted in two different locations within an apartment balcony (0.0 m and 1.6 m from t he w indow) and u nder d iffering l ight intensities (13.5 μmol･m-2 ･s-1 and 96.4 μmol･m-2 ･s-1). Ninety-seven species of succulents from 23 genera were selected as experiment material, based on the criteria of propagation ease and affordable price. As a result, 37 species were selected as suitable for indoor decoration and consisted of 27 species (Echeveria macdougallii, E. 'Momotaro', E. 'Fun Queen', E. derenbergii, E. 'Pulv-oliver', E. multicaulis, E. lilacina, Crassula 'Buddhas Temple', C. mesembryanthemoides, C. ‘Moonglow’, C. ovata, C. ovata 'Gollum', C. ovata 'Tricolor', Aeonium arboreum 'Atropurpureum', A.sedifolium × A. spathulatum, A. sedifolium, Graptoveria 'Albert Baynes', × Graptoveria 'Silver Star', Pachyphytum oviferum, P. oviferum 'Momobijin', Sedum clavatum, S. morganianum, Sinocrassula yunnanensis, S. densirosulata, Kalanchoe tetraphylla, Cotyledon tomentosa, Adromischus cooperi) from Crassulaceae, 6 species (Haworthia fasciata, H. retusa, H. turgida var. longibracteata, Aloe perfoliata, A. juvenna, Gasteria gracilis) from Asphodelaceae, 2 species (Corpuscularia lehmannii, Faucaria bosscheana) from Aizoaceae, 1 species (Peperomia graveolens) from Piperaceae, a nd 1 s pecies (Sansevieria trifasciata ‘Hahnii’) from Asparagaceae. The majority (67.6% of the selected species) of the selected species had overwintering temperature of 0 – 5°C and while most of the selected species had fibrous roots, all species with thick roots were selected as suitable. Of the selected species, 78.3% had a growth rate of moderate level or faster, and 56.8% were summer growing type. Sixty species were found to be unsuitable, and included 5 genera from Crassulaceae (× Pachyveria, × Sedeveria, Graptopetalum, Orostachys, Monanthes) and o ne g enus f rom Asteraceae (Senecio).

To increase the availability of Maxillaria species and cultivars, we investigated the volatile floral scents in eight species and cultivars of M. tenuifolia, M. variabilis, M. variabilis 'Alba', M. variabilis 'NxO', M. variabilis 'Brown', M. variabilis 'Red', M. variabilis 'Nana', and M. sangnine. The volatile components were analyzed using headspace-solid phase microextraction-gas chromatography-mass spectrometry (HS-SPME-GC-MS). We identified 46 volatiles in eight species and cultivars of Maxillaria. α-pinene, eucalyptol, trans-β-ocimene, α-copaene, and β-caryophyllene were major flavor components in the eight Maxillaria species and cultivars. A principle component analysis (PCA) showed that M. tenuifolia, M. variabilis, M. variabilis 'NxO', M. variabilis 'Brown', M. variabilis 'Nana', and M. sangnine (major components: sesquiterpenes) were located closely together on t he s core p lot. However, M. variabilis 'Alba' and M. variabilis 'Red' (major components: monoterpenes) were located closely on the score plot and not analyzed coconut flavor.

Since a free-learning semester has been introduced to middle school curriculum, interest in career experience programs has increased. To respond to this new demand, we developed a continuous agriculture-related career experience program linked with STEAM (Science, Technology, Engineering, Arts, and Mathematics) education, and we examined the program’s effects on the job awareness of middle school students. The program was conducted from April 8, 2015 to June 24, 2015, and consisted of 12 classes. The direct experience subprogram was based on 13 different horticultural activities that reflect producing (nine programs), cooking (two programs), and sales (two programs) of horticultural produces. For the indirect experience subprogram, we preliminarily selected 10 representative agricultural jobs, and based on the keywords analyzed from 7 direct experience programs, we chose to introduce seven jobs to the students by videos and the three others by written material. We then investigated the effect of introductory videos on job interest, understanding, and preference by the students. We found that the student’s interest, understanding, and preference regarding each job were significantly improved when direct experience and video watching were combined. Career awareness was improved for gardener (47.0%), nursery grower (42.0%), rural extension official (31.1%), eco-friendly farm material developer (30.9%), agricultural research official (23.4%), plant doctor (19.8%), and agricultural wholesale distribution experts (9.3%). Conclusively, it is expected that career experience programs have the greatest effect on students when both interest in the job and participation on direct experiences are encouraged.

This study was performed to develop a stable cultivation technology switchable from an open system to a closed system for cut roses. Closed growing system in different ratios of drainage and water was supplied to investigate the accumulation of macronutrients and roses growth. In treatment by the 30% mixing ratio of drainage to water, total amount of drainage was reduced since the medium stage of growth. However, in treatment by the 10% mixing r atio, total o ne o f drainage c ontinuously was increased to the blossom stage. Electric conductivity (EC) of initiation drainage on 10% mixing treatment was stable to t he blossom s tage. However, EC of d rainage on 3 0% mixing treatment was slightly increased. The pH of the drainage was maintained between 5.0 and 5.5 in both treatments. Phenolic compounds were not detected in the drainage, while organic acids were detected a little bit. When recirculated drainage was continuously used, the concentration of NO3-N, Ca, Mg, S, and K in the drainage was increased, but that of P was decreased. The content of Ca in the leaves was inversely proportional to the drainage mixing rate. No treatment showed significant differences in photosynthesis and chlorophyll content, and in quality and productivity of the cut rose

The present study was conducted to control Botrytis growth of cut roses during transport by applying hot water dipping. Water temperatures ranging from 40 – 70℃ and dipping time from 10 – 90 s were evaluated in vitro and in vivo. Hot water dipping at 50℃ inhibited mycelial growth depending on dipping time. Water temperature over 60℃ completely inhibited the pathogen growth even at exposure of 10 s while water below 40℃ did not have any effect. However, temperature over 60℃ rapidly damaged the tissue of rose petals. Dipping time below 40 s at 55℃ showed no significant difference on electrolyte leakage compared to control. In vivo, dipping flower heads in hot water reduced the severity of Botrytis rot. Dipping for 20 – 90 s at a temperature of 50℃ was more effective than at higher or lower temperatures. Heat treatment increased respiration rate and decreased slightly solution uptake, transpiration, fresh weight of flowers but dipping below 50℃ for 20 s did not affect vase life.

Domestic cut roses tend to be poor in quality especially during summer. This seasonal drop in quality of cut flowers has caused serious export disruption such as inadequate volume or price decline. We investigated the relationship between environmental factors and vase life (VL) of cut roses. Six cut rose varieties, ‘Antique Curl’, ‘Beast’, ‘Iguana’, ‘Legato’, ‘Pink Heart’, and ‘Red Pocket’, were investigated from three commercial farm greenhouses (Farms A, B, a nd C ). The VL of cut flowers ranged f rom 5.8 to 18.2 days depending on the variety. Considering 16 days as the minimum VL required for exportation during the summer season, only two varieties ‘Antique Curl’ and ‘Beast’ would qualify for exportation. VL was significantly negatively correlated to only relative humidity (RH) (r = - 0.69*) among various environmental factors and only to peduncle length (r = - 0.60*) among plant morphological items. Thus, controlling RH is key to improve the vase life of cut roses during the summer production for export.

This study aimed to evaluate the growth of Ilex cornuta Lindl. & Paxton, Cotoneaster dammeri, Ardisia pusilla ‘Variegata’, and Ilex aquifolium ‘Silver Queen’ when sphagnum moss was used for purpose of export and the pottery plants were submitted to different watering and quick versus slow release fertilizer. The growth of I. aquifolium 'Silver Queen' watered 50 mL every 3 days was the highest with 16.0 cm in plant height, 79.3 in leaf number, 178.2 cm2 in leaf area, and 18.5 g in fresh weight. C. dammeri also grew best when watered every 3 days. However, the survival rate was 100% for I. aquifolium 'Silver Queen' watered at 12-day intervals and C. dammeri watered at 6-day intervals or more. With quick release fertilizer of 1,000 – 2,000 mg·L-1 applied at 1- to 4-week intervals, I. aquifolium 'Silver Queen' and C. dammeri, plant height, number of leaf, leaf area, and fresh weight increased as fertilizing intervals were shorter. During the short quick release fertilizing at 4-week intervals, the survival rate remained 100%. With slow release fertilizer of 0.5 mg, 1 mg, or 2 mg applied at intervals of 6, 12, and 18 weeks, I. cornuta Lindl. & Paxton and A. pusilla ‘Variegata’ plant height, number of leaf, leaf area, and fresh weight increased with increase of fertilizer amounts and shorter intervals of fertilizing. However, concentration of fertilizer had no effect on plant growth. During the short slow release fertilizing at 18-week intervals, the survival rate remained 100%. Therefore, to improve the quality of small woody plants in the pottery aimed for export, it is preferable to water at intervals of 3 days after acclimation, and use either quick release fertilizer at 3-week intervals or slow release fertilizer at 12-week intervals.

This study was conducted to establish a propagation system by shoot tip culture of Hosta plantaginea ‘Joseon’, of which production has increased as landscape plants and cut foliage. We evaluated the effects of culture methods (drum shaker in liquid, filter paper bridge in liquid and solid media), media (1/2MS , 1MS, 2MS), cytokinin (BA, kinetin, TDZ), and light quality (fluorescent lamp, red LED, blue LED, red LED + blue LED) on shoot multiplication and rooting. In the treatment by culture methods, the highest number of shoots (2.4 shoots per explant) was obtained on liquid media with drum shaker (BA 4.0 mg·L-1+ NAA 0.2 mg·L-1) and solid medium (BA 4.0 mg·L-1+ NAA 0.2 mg·L-1), but the shoots showed vitrification symptoms in liquid media. In media treatment, underground growth was good in 1/2MS and 1MS: overground growth was good in 1MS and 2MS but shoot length of 2MS tended to be shortened. In the treatment by cytokinin, kinetin 2.0 mg·L-1+ NAA 0.2 mg·L-1 and k inetin 4.0 mg·L-1+ NAA 0.2 mg·L-1 showed the highest number of shoots (3.4 and 3.3 shoots per explant, respectively). In the treatment by light qualities, red LED showed the highest number of shoots, shoot length, leaf number, fresh weight, dry weight, and leaf area. Red LED enhanced shoot length elongation, but chlorophyll content was lower. The content of chlorophyll was highest in blue LED, but the number of the shoots was lower. Shoots were rooted easily on basa MS medium without NAA, showing 100% of rooting. As a result, it might be considered that roughly 6,561 plants can be produced through subculture for one year in vitro from only one shoot tip of H. plantaginea ‘Joseon’ in MS semi-solid medium with BA 4.0 mg·L-1+ NAA 0.2 mg·L-1 or with kinetin 4.0 mg·L-1+ NAA 0.2 mg·L-1.

This study aimed to evaluate the growth of Ilex cornuta Lindl. & Paxton, Cotoneaster dammeri, Ardisia pusilla ‘Variegata’, and Ilex aquifolium 'Silver Queen' when sphagnum moss was used for media, and the pottery plants were submitted to different temperatures and shade levels. After transplantation to pottery pots with Sphagnum Moss, the growth of I. aquifolium 'Silver Queen' at 25℃ of soil was the highest with 16.8 cm in plant height, 75.0 in leaf number, 256.5 cm2 in leaf area, 18.9 g in fresh weight. I. cornuta Lindl. & Paxton and A. pusilla ‘Variegata’ were in the same range but soil temperatures of 15℃, 20℃, or 30℃ had no effect and the survival rate remained 100%. On the other hand, when I. aquifolium ‘Silver Queen’ was submitted to night temperatures of 4℃, 8℃, 12℃, or 15℃, the following results were obtained: 14.1 cm in plant height, 70.0 in number of leaf, 221.1 cm2 in leaf area, and 18.9 g in fresh weight at 15℃; C. dammeri showed similar results. The survival rate at night temperature 4℃ or 8℃ was 100%, but the plant growth was sluggish. In shading 30% or 60%, the fresh weight of I. aquifolium ‘Silver Queen’, I. cornuta Lindl. & Paxton, and A. pusilla ‘Variegata’ was increased at shading 60% as the plants became taller. Non shading increased the leaf number and leaf area of plants compared with shading. In conclusion, the quality of small woody plants in pottery can be improved when the plant is grown before shipping at a soil temperature of 25°C and a greenhouse night temperature of 15°C, at 30% shading after acclimation

The National Institute of Horticultural & Herbal Science achieved the breeding of the moon cactus cultivar ‘Hahong’ with dark red color in 2013. Initially, the red dark colored 'Seolhong' and 'Gohong' cultivars were crossed in 2009. Their seeds were harvested after 2 months, sterilized by C2H5OH 70% and NaOCl 2%, and then sowed in 100 mL flasks filled with Kyoto medium + Charcoal 0.1%. The bottom of the germinated shoot was cut, grafted in vitro into a young vine cactus, Hylocereus trigonus, and then planted in a test tube with the same medium. After 6 months, the young grafted cactus was moved into the greenhouse and hardened for 7 days. The cactus was grafted in vivo once a year for four years, the characteristics of growth were surveyed three times from 2011 to 2013, according to the guidelines for the conduct of tests for distinctness, uniformity and stability of Gymnocalycium mihanovichii. ‘Hahong’ has a flat round shape, dark red skin color (R 46B), an average of 8.3 ribs (8 – 10 ribs) similar to ‘Seolhong’. The spine on the body has gray and brown colors and grows up to 4.1 mm in average in a straight shape. The tubercle on the rib is projecting, with a diameter of 39.6 mm, and produces 14.2 offsets in average at 10 months from planting. The preference score for this cactus is 4.2 on a five-point scale. On June 1, 2015, ‘Hahong’ was registered (registration No. 5561) and is now protected by Korean Seed Industry Law.

Originally, most lilies for cut-flower were Asiatic and Oriental hybrids. These days, however, interspecific hybrid cultivars are reared worldwide and customers expect various flower types and colors. ‘Cream Bell’ cultivar is an interspecific OT hybrid (Oriental hybrid × Trumpet hybrid) bred at Chungnam-do ARES in 2013. In 2007, interspecific pollination by stigma cut-style of OT hybrid 'Yelloween' and Trumpet hybrid 'Pink Perfection' was conducted to foster the cultivar with flourishing growth, high resistibility to leaf burn and leaf blight. It went through seed culture, multiplication, and seedling from 2007 to 2010. Breeding hybrid evaluation showed that the quality of the hybrid is excellent. From 2011 to 2013, unheated vinyl house cultivation and cultivar registration were performed for characterization. The flower of this lily is clear cream and primrose in color, without spots. It has a width of 18.2 cm and the consistent large flower has a trumpet style, along with many inner and outer perianth overlap. The stem has an oatmeal color and mid-size leaves. Flowering time in the central district starts on the 27th June, which seems to be relatively early. The flower direction is oriented inflorescence and semi-upward, and the cultivar shows robustness to leaf burn and leaf blight. The bulb can be grown with stem and leaf after cutting the flower, as the plant is quite tall. Also, with the high rate of bulb growth, bulb production is convenient. Cut flower production is of high quality with only routine cultivation control (disease, insects, nutrient, and moisture).

At the Flower Research Institute of Chungcheongnam-do agricultural research and extension service, ‘Shusin’ and ‘ST06-005-11’ were crossed and a candidate descendant, ‘ST09-173-06’, was selected based on disease resistance and other morphological traits. We intensively tested the candidate line on various characteristics, including the floral qualities through shading and retarding culture, starting from year 2009. In 2011, we registered this line as the standard chrysanthemum (Dendranthema grandiflorum Ramat.) cultivar ‘Baekseol’. The natural flowering time of 'Baekseol' starts the 24th of October, which is earlier than ‘Jinba’ (29th of October). ‘Baekseol’ is favorable at winter growing season and the flower vase life is 17 days. The cut flower length of ‘Baekseol’ is 87.2 cm, which is shorter than ‘Jinba’ (97.4 cm) and the lateral branch number of ‘Baekseol’ (15.6 per plant) is less than ‘Jinba’ (21.8 per plant). The flower size of ‘Baekseol’ is 14.6 cm (‘Jinba’, 13.4 cm) and the petal number per flower is 430.4 (316.3 per flower for ‘Jinba’). Careful nutrient management is required at t he e arly g rowing s tage. T he s hort d ay t reatment i s appropriate when the plant is approximately 40 - 45 cm. In addition, flower bud differentiation temperature is approximately 16 - 17℃.

‘Woonbaek’ bred by the National Institute of Horticultural & Herbal Science, Rural Development Administration (RDA) in 2011 is a new white standard chrysanthemum cultivar. The artificial crossing was made in 2007 between ‘Suishin’ and ‘Gilyangma’. ‘Suishin’ was the autumn-flowering standard chrysanthemum cultivar with white petals and low temperature flowering type, while ‘Gilyangma‘ grew well at low temperature. Vigorous plants with numerous white petals and low branches were selected in 2008. Genetic trait investigations of the line (07B1-659) had been performed between 2009 and 2011 and included flowering stability, uniformity, and year-round productivity, the final test of the producer and consumer preference. ‘Woonbaek’ is a new standard cultivar that blooms in late October in natural condition. The flower has numerous petals, a green colored center, and a s table flower shape. The number of ray flower was 249 and flower diameter was 14 cm. Vase life was approximately 21 days in autumn season. The stem was not significantly thinner at the upper end. ‘Woonbaek’ was applied as No. 2012 - 244 on March 23, 2012, for variety protection and its plant variety protection rights have been registered as No. 4839 on March 17, 2014, at the Korea Seed and Variety Service.
