The influence of rainfall during the ripening stage on pre-harvest sprouting, seed viability, and seed quality was investigated in two Korean rice cultivars, Shindongjin and Hopum. When the rainfall was artificially treated in a greenhouse, HP started to pre-harvest sprouting at three days of rainfall treatment (DRT), but Shindongjin did not show pre-harvest sprouting at 40 DAH treatment and just 0.3~0.8% at 50 DAH, which was much lower than 15.3~ 25.8% of Hopum in the same treatment. After harvest, the seed germination of Hopum decreased about 10~25% compared to non-treated seeds, but that of Shindongjin decreased much little rate than that of Hopum. The seed longevity tested by accelerated aging decreased with prolonged rainfall period in both cultivars, but the varietal difference was clear; Shindongjin could withstand longer accelerated aging than Hopum. Shindongjin maintained its germination (>50%) ability after 15 days of accelerated aging regardless of the rainfall treatment period and time, but Hopum dropped below 50% germination ability after only 5 days of accelerated aging. In conclusion, rainfall during the ripening stage induced not only pre-harvest sprouting, but also reduced seed quality and longevity during storage, which varied between two cultivars.

The purpose of this study was to develop the cost-effective and efficiency seed longevity prediction method of rice (Oryza sativa L.) germplasm for viability monitoring. To find an optimum predicting method for rice seed longevity at genebank, an accelerated ageing (AA) test, a controlled deterioration (CD) test and a dry-heat treatment (DHT) were conducted to the four groups of rice germplasm based on ecotype, such as Indica, Japonica, Javanica and Tongil type. Among the three artificial aging treatments, the dry-heat treatment of 36 hours at 90°C is suggested as a routine predictive test method of rice germplasm longevity at a genebank. The distribution of germination rate on 3,066 accessions which conserved 26.5 years at 4°C showed similar trend with the result of distribution by dry-heat treatment at 90°C on 36 hours using 106 accessions of rice selected samples which composed four ecotype groups. The results show that the dry-heat treatment affect not only predicting the rice seed longevity but also determining effective interval for monitoring germination of rice germplasm in genebanks.

The purpose of this study was to know the seed longevity of rice (Oryza sativa L.) germplasm for effective viability monitoring. The longevity was determined via germination tests of 3,066 accessions of rice germplasm from the National Agrobiodiversity Center, Rural Development Administration, Korea. The rice germplasm accessions have been conserved at a mid-term storage (4°Csealed metal can on either sides for 25~26.5 years. The final germination percentages of 3,066 rice germplasm accessions of 6.5±1.0% seed moisture content with 94% initial germination stored at 4°C for 26.5 years declined to 47% while at -18°C for 25 years maintained high germinability as 93%. Germination time courses, which represent the average performance of rice ecotypes stored at 4°C and 30% RH, were fitted regression equation, to calculate the time at which germination characteristically declined to 50% (P50). These P50 values of Indica, Japonica, Javanica and Tongil type in rice were 39.9, 22.9, 25.4 and 31.8 years, respectively. The rice germplasm stored at 4°C could be clustered in 4 groups using quartile of final germination after 26.5 years storage. The seed longevity (P50) of each group was estimated by regression equation of changed germination percentages according to storage periods. The P50 values of group Ⅰ, group Ⅱ, group Ⅲ and group Ⅳ were 21.1, 23.6, 30.0 and 75.7 years.

Rice is the most important staple food crop of almost half of the world`s population. In rice, seed longevity is major factor for production and storage potential of seeds. But it is faced with grain degradation and loss of seed viability. Lipoxygenases(LOX) are a family of enzymes related to the seed longevity. LOX activity in rice grain is present in a bran-milling fraction. It is also observed that rice embryos contains three isozymes activites, Lox1, Lox2 and Lox3. Among those, the Lox3 isozyme is known as the major component in the embryonic tissue. In this study, genetic structure variability of three seed longevity related genes, Lox1, Lox2 and Lox3 were examined by using whole-genome resequencing data of 137 accessions of rice core set. The new SNPs and InDels in the exon regions identified through haplotyping analysis would be useful to develop new varieties with improved storage ability of rice in the future molecular breeding.

It is well known that Dharial (Bangladesh origin and weedy rice line) has longer seed longevity than indica and japonica rice varieties. To study the genetic basis of seed longevity of Dharial, we developed 240 BC3F7 backcross recombinant inbred lines derived from the crosses between Dharial (a donor parent) and two korea rice accessions (recurrent parents) including Ilmi and Gopum, respectively. Among these lines, we selected two introgression lines with longer seed longevity and named them Ilmi-NIL and Gopum-NIL. Also, we developed an EMS-induced mutant line from Dharial which has shortened seed longevity, and named it Dharial-EMS. We performed re-sequencing of four rice accessions that are Dharial, Dharial-EMS, Ilmi-NIL, and Gopum-NIL. A total of 706×106 raw reads were generated which provided sequence data over 46x rice genome coverage per each accession. We did genome-wide variation analysis comparing produced re-sequencing data and the re-sequencing data of Ilmi from NABIC database with the Nipponbare reference sequence. By graphical analysis of SNP distribution in rice genome of the five accessions, we could select candidate chromosomal segments introgressed from Dharial in Ilmi-NIL and Gopum-NIL. The introgressed chromosomal segments were in seven regions in Ilmi-NIL and eight regions in Gopum-NIL, and four common introgressed regions between Ilmi-NIL and Gopum-NIL were identified. 2,758 SNPs between Dharial and Dharial-EMS were found in the introgressed regions. Also, we detected 450 genes including at least one SNP among these SNPs. This result will facilitate identification of genes and development of molecular markers for improvement of seed longevity.

Daily shedding pattern and longevity of pollen are important consideration for the evaluation of gene flow of transgenic plants. During the day, the pollen shedding pattern of zoysiagrass was determined in the lawn by using a device to collect airborne pollen on a glass slide, resulting that the pollen grains were released predominantly between 7:00 and 9:00. The result was also supported by in vitro pollen germination test, which was performed with pollens collected from 1:00 through 24:00 at 1h interval. Influence of temperature and humidity on pollen longevity was determined by germinating pollen at 25°C after incubating them for 10, 30, 60, and 180 min under different temperatures and humidity with pollen of zoysiagrass that opened freshly at about 9:00. The result showed that pollen longevity of zoysiagrass was sensitive to change of temperature and humidity and longest under the temperture and humidity of 15-20°C and 80-99%, respectively. Under natural conditions with the same method as upper controlled conditions, was determined pollen longevity. Under sunny atmospheric conditions, pollen longevity decreased to 20% in 60 min, with a complete extinction in 120 min. Under cloudy atmospheric conditions, pollen remained viable up to 450 min, with about 20% longevity after 360 min. No significant difference was found between GM and non-GM plants in their pollen longevity.

Geneally, rice seeds regardless indica or japonica are showing low germination ratio or completely lost germination ability together with lost of good eating quality under high temperature and humidity conditions. Thus, this study was designed to evaluate a longevity for conservation of good eating quality during long term storage in rice. For the longevity evaluation, germination ability was studied after 5 days of high temperature and humidity stress (50℃/RH 95%). Dharial, originated from Bangladesh and showing weedy type with red pericarp, was selected as a good donor for longevity genes. A mutant was developed from Dharial through EMS mutagenesis and two populations of Dharial/4*Ilmibyeo and Dharial/4*Gopumbyeo were also developed for genetic study. In the 2-DE analysis followed by MALDI-TOF MS with wild and mutant lines, several candidate genes were identified. In the longevity test of two populations, a few lines showing good germination ability after high temperature and humidity stress were selected and subjected to confirm the relationships between longevity and conservation of good eating quality under long term storage.

전통 용기인 미세다공성의 옹기를 화병으로 활용하기 관행의 자기 및 유리 화병과 옹기 화병에 장미 절화를 꽂고 절화수명을 비교하였다. 절화보존제 용액과 수돗물이 들어있는 3가지 재질의 용기에 장미 ‘Aqua’와 ‘Covernet’의 절화를 꽂은 후 절화수명과 미생물수, 수분흡수량, 절화 생체중 등을 조사하였다. 그 결과, 두 품종 모두 옹기 화병에서 절화수명이 길었으며, 절화보존용액이 수돗물에 비해 절화수명을 연장시켰다. 특히 절화보존용액을 넣은 옹기 화병에서 두 품종 모두 절화수명이 14일 수준으로 가장 길었다. 10일간의 누적 수분 흡수량은 절화보존용제를 넣은 옹기 화병에서 ‘Aqua’가 17.0mL, ‘Covernet’가 15.1mL로, 수돗물의 13.6과 13.8mL보다 많았다. 생체중은 절화보존제 처리가 수돗물에 비해 생체중 감소를 크게 지연시켰으며, 옹기도 다른 재질의 화병에 비해 생체중 감소 지연 효과가 있었다. 특히 옹기에 절화보존제를 처리한 ‘Aqua’ 품종의 경우 처리 8일 후에도 초기 생체중의 88% 수준을 유지하여 상대적으로 수분흡수가 원활했음을 알 수 있었다. 반면, 자기 화병에 절화보존제를 처리한 경우 79%, 옹기 화병에 수돗물을 넣은 경우 72%였다. 미생물수 측정 결과, 옹기의 보존용액의 총 균수가 다른 용기에 비해 적게 나타났다. 8일째 옹기에 ‘Covernet’을 꽂은 보존액에서 유지할 경우, 자기나 유리의 용기에 비해 비교적 적은 수의 미생물이 검출되었지만 보존 용기 간의 차이보다는 절화보존제 처리구에서 무처리에 비해 미생물의 증식이 현저히 감소하였다. 옹기는 절화 장미의 물올림을 유지시켜 주기 때문에 도관 폐쇄에 의한 꽃목굽음 현상이 억제하고, 절화보존제를 병행하여 사용함으로써 미생물의 발생을 억제하여 절화수명을 연장할 수 있다.

Recently many administrative institutes try to improve the viability of rural villages. For increasing the viability, not only infrastructures but internal vitality is necessary in rural villages. Nonetheless, most of governmental projects have been focused on infrastructures. For this reason, RDA(Rural Development Administration) designed and performed the RHL(Rural Healthy and Longevity village) project. This RHL project is not easy to evaluate the outcome because it consists of very intangible project items. In this paper, we developed a scoring model to evaluate the result of the RHL project. The scoring model based on DEA(Data Envelopment Analysis) was suggested to evaluate the quantity of personal activities in each village. Personal activities are classified into five categories: regional life, social life, productive life, outdoor life and indoor life. Evaluating indices of each category are developed and weighting values are evaluated by AHP(Analytic Hierarchy Process). The developed model was applied to Kumsan village and examined its applicability.

In this study, the longevity index was suggested for researches about social and environmental effects to human immorality and criteria for defining longevity area were developed using statistical analysis. Candidates indexes based on researches about the tend of human death ratio were investigated. As a result statistical analysis, ratio of population over 85 yearn old and over 65 years was selected as a longevity index. Statistical analysis on the longevity distribution at each district showed that 'eup' and 'myun' are appropriate spatial unit to study social and geographical characteristics of longevity. The spatial analysis using the ArcViewTM with the suggested index shows the time dependent variances of degree of immorality and spatial relationship between degree of immorality and human migration.

Spatially distributed characteristic of longevity regions analysed using GIS tools. Fundamental factors for long life are categorized into natural conditions and artificial conditions. Degree of longevity is defined and used as a key parameter in analyzing longevity region. It is visually shown that aging areas are moving with time and variances of social and economic status. It is concluded that the degree of longevity is increased with improving living quality because of improvement of economic activities and living environment. However, longevity regions of recent times have slightly reversed tendency against urban areas in the manner of moving toward areas where social and economical activities are relatively weaker.
