        This study was conducted to determine the optimum conditions for the treatment of polyamine to promote pollen germination and improve the fruiting rate by overcoming fertilization defects in low-temperature strawberry cultivation. The optimum temperature for pollen germination of strawberries was 30 for Seolhyang and 25 for Maehyang, and Seolhyang had a higher pollen germination rate than that of Maehyang. The addition of polyamines, namely spermine and putrescine to the medium improved the pollen germination rate and spermine treatment showed a better effect than putrescine treatment. The proper polyamine type and treatment concentration for enhancing the potency of pollen germination was 500 μM of spermine for both Seolhyang and Maehyang, which improved the pollen germination rate by 19-23% compared with that of the control. However, combined treatment of spermine and putrescine, resulted in a lower germination rate lower than that of the single treatment. Our results indicated that the treatment of polyamines during flowering in protected cultivation of strawberrise can improve the fruiting rate by overcoming the problem of poor pollen germination due to low temperature.

        The purpose of this study was to investigate the effects of defoliation treatment on the growth and yield of strawberries. There was a remarkable growth in the above-ground part and root of untreated strawberry plants possibly due to higher amount of photosynthesis, while overall plant growth was suppressed as the level of defoliation treatment increased. In both the “Seolhyang” and “Maehyang” cultivars examined, defoliation treatment resulted in small fruits and a low number of fruits per plant. Notably, 50% defoliation significantly reduced the number of fruits per plant to 8.2, compared to 13.8 in untreated plants. Defoliation treatment also negatively influenced the fruit quality including color, sugar content, and solid-acid rate. However, no significant changes in fruit firmness was observed in either cultivar. Therefore, retaining enough leaves without defoliation treatment can be important to increasing fruit yield, producing high quality fruits and saving labor required for defoliation.

        The purpose of this study was to investigate the effect of shading on the growth and productivity of strawberries. Photosynthesis was normally achieved under natural light without shading treatment, and vegetative growth of under- and aboveground part of strawberry plants were excellent. Strawberry fruit productivity and quality were different depending on shading conditions. In natural light, they were improved possibly by balanced vegetative and reproductive growth. However, under light-shading conditions with insufficient sunshine, photosynthetic activity deteriorated and carbohydrate production was therfore inadequate; this adversely affected plant height and quality. The negative effects were more pronounced at 50% shading condition. Shading treatments resulting in insufficient sunshine had a detrimental impact on plant productivity and growth; this implies that proper shading conditions could heip improve yield and fruit quality.

        In this study, we investigated the influences of abnormal high temperature on growth, yield and physiologically active substances of the strawberry. General strawberry cultivars in the 20℃ growth condition showed much better growth of leaf number, length, diameter along with plant height, compared with those in 22.5℃ or 25℃. But the cultivars of both ‘Sulhyang’ and ‘Mehyang’ showed good growth and development at 25℃ with the roots showing great growth at 20℃. The quality and yield of the strawberry were best in the 20℃ growth condition, but the merchantability deteriorated in the 25℃ high temperature condition. As for the content of the physiologically active substances of the strawberry, it increased at 20℃, the optimum growth temperature, but decreased at 25℃. The physiologically active substances in the strawberry differed among the cultivars, the contents of cyanidin-3-glucoside, cinchonine, ellagic acid and cinnamic acid higher in the ‘Mehyang’, whereas the content of fisetin is higher in the ‘Sulhyang’ cultivar.Consequentially, the high temperature in summer has a negative effect on the physiological active ingredients of the strawberry, which was increased in the strawberry cultivated at proper temperature, and high quality strawberry production was possible.

        This study investigated the applicability of horticultural media with recycled coir substrates the growth of Chinese cabbage (Brassica campestris L. ssp. Pekinensis) and lettuce (Lactuca sativa L.) crop. The six different types of coir based substrates were A, Coir 45: Perlite 35: Vermiculite 12: Zeolite 8 (%), B, Coir 55: Perlite 25: Vermiculite 12: Zeolite 8 (%), C, Coir 65: Perlite 15: Vermiculite 12: Zeolite 8 (%), D, Coir 75: Perlite 5: Vermiculite 12: Zeolite 8 (%), E, Coir 85: Perlite 5: Vermiculite 5: Zeolite 5 (%) and F, nursery media (control). The pH and Electric conductivity of the horticultural nursery media were 6.06–7.00 and 0.45–1.10 dS/m-1, respectively. The nursery media containing coir substrates had higher level of Total N, Ca, K, Mg and P than those without coir. Additionally, it was observed that the growth of Chinese cabbage was the best on D (containing 75% coir) while that of lettuce was the best on E (containing 85% coir). In general, when substrates containg a higher percentage of coir were used, the growth of Chinese cabbage and lettuce was ideal. Additionally, the P, Ca, and Mg content in both plants was not significantly altered by the amount of coir present in the media. However, with an increase in the amount of coir substrate, the chlorophyll, N, and K content was increased. After harvesting, there was no significant difference in the chemical properties of the horticultural nursery media of both plants. Thus, it can be suggested that, coir substrate after a single use could be recycled as horticulture nursery media.

        The current study was performed to investigate the effect of recycling coir substrates on the growth, fruit yield, and quality of strawberry plants. Analysis of physical properties revealed that the pH of a fresh coir substrate was 5.04 while those of substrates reused for one and two years were 5.20 and 5.33, respectively. The electrical conductivity (EC) of a new substrate was as high as 4.58 dS·m−1. This can cause salt stress after transplanting. The EC tended to decrease as the substrate was recycled, and the EC of a two-year recycled substrate was 1.48 dS·m−1. The fresh substrate had lower nitrogen and calcium concentrations, but higher phosphate, potassium, and sodium concentrations than the recycled coir substrate. The coir substrates recycled for one or two years maintained better chemical properties for plant growth than the fresh substrate. Strawberry growth varied depending on the number of years that the coir substrate was recycled. In general, strawberries grown in substrates that had been reused for two years did better than those grown in substrates that had been reused once or were fresh. Ninety days after transplanting, a plant grown in a substrate that had been reused for two years contained 25 leaves, which was 3.6 more than with a fresh substrate. In addition, the plants grown in a substrate that had been reused for two years exhibited larger leaf areas than those grown in other substrates. Coir substrates that had been reused for one year increased the number and area of leaves, but not as much as the substrate that had been reused for two years. One- and two-year reused coir substrates increased the weight of strawberries produced relative to the unused substrate, but the difference was not statistically significant. The plants grown in two-year reused substrates were longer and wider, as well. Also, the number of fruits per plant was higher when substrates were reused. Specifically, the number of fruits per plant was 28.7 with a two-year reused substrate, but only 22.2 with a fresh substrate. The fruit color indices (as represented by their Hunter L, a, b values) were not considerably affected by recycling of the coir substrate. The Hunter L value, which indicates the brightness of the fruit, did not change significantly when the substrate was recycled. Neither Hunter a (red) nor b (yellow) values were changed by recycling. In addition, there were no significant changes in the hardnesses, acidities, or soluble solid-acid ratios of fruits grown in recycled substrates. Thus, it is thought that recycling the coir substrate does not affect measures of fruit quality such as color, hardness, and sugar content. Overall, reuse of coir substrates from hydroponic culture as high-bed strawberry growth substrates would solve the problems of new substrate costs and the disposal of substrates that had been used once.

        The present study was conducted to develop seed treatment for the production of healthy and clean peanut sprout. Dry heat treatment of peanut seeds reduced the incidence of the rot. The seed treatment condition at 52℃ for 10 h. was the most efficient without inhibiting seed viability significantly. Seeds were dark cultured at 27℃ for up to 9 days. The treatment of Indole-B and gibberellic acid influenced germination, T50, fresh, dry weight, hypocotyl length, hypocotyl length diameter, root length, number of lateral root and epicotyl of peanut sprout. There were no differences in the germinability of peanut seeds between gibberellic acid treatment methods but higher fresh weight was observed in the GA3 solution spray after 2 hour water soaking. The general growth and lateral root development of peanut sprouts were suppressed by Indole-B which is used for inhibiting root formation and promoting hypocotyls. The treatment of gibberellic acid promoted hypocotyl elongation, but it did not influence on the growth of hypocotyls and root system.

A의 함수량은 63.6g 이었으나 B~E는 70g 이상으로 유의하게 높았다. B의 pH는 5.6으로 가장 높았으며 그 다음으로 C, D, E 순이었다. EC의 경우 A가 2.16ds/m 으로 가장 높았으며 B~E의 경우 0.43ds/m 이하로 매우 낮았다. 사용한 배지의 물리성은 변하지 않았다. 엔다이브의 엽수는 D, E에서 19.2장으로 가장 많았다. 상추의 엽장과 엽폭은 B~E에서 각각 19cm, 11cm 정도로 배지 간에 차이는 없었으나 배지 A의 14.7cm, 9.1cm보다 유의하게 증가하였다. 엽수와 근장의 경우 유의차는 없었지만 잎의 크기와 마찬가지로 B~E가 A 보다 많은 것으로 나타났다. 머스타드의 엽장은 B~E가 A에 비해 통계적으로 유의하게 큰 것으로 나타났다. 토마토의 초장은 C~E에서 50cm 정도로 A에 비해 유의하게 생장이 증가하였다. 개화일은 D가 7월 28일로 가장 빨랐으며 그 다음이 E로 7월 30일이었다. 과실수는 유의한 차이는 없었으나 E가 8개로 가장 많았다. 이상의 결과로 보아 본 실험에서 조제한 배지는 기존의 원예상토에 비해 가볍고 보수성이 우수하였다. 또한 식물의 생육과 배지의 물리화학적인 특성을 고려할 때 엔다이브, 상추, 머스타드, 토마토의 재배에 적합한 배지는 E(코코피트:피트모스:수태=2:5:3)로 판단되었다.
