This study was conducted to improve the postharvest storage techniques of managing and storing seeds, totest qualities and viabilities of the seeds and to examine the germination rate and the protein expression of Achyranthesjaponica Nakai. The seeds collected from different areas of Je-Cheon and Gwang-Ju were stored with different temperaturesand durations. Two plant growth regulators and two seed priming were treated to investigate their effect on the germinationrates and the days required for germination. The weight of one hundred seed collected in Gwang-Ju was heavier than thosein Je-Cheon. Seed length collected in Gwang-Ju was also longer about 5.12㎜ than those in Je-Cheon about 4.90㎜ andseed width was longer in Gwang-Ju than those in Je-Cheon. The rates of seed germination in two different collection areaswere higher about 2.9 to 13.0% in Gwang-Ju compared to those in Je-Cheon. Comparing its rates with the storing tempera-tures and durations, they were not clearly different in between 4℃ and 25℃ and they also were gradually decreased withgetting longer storing durations. The germination rates treated by plant growth regulators were higher with GA3 than thosewith Kinetin. The highest seed germination rate was appeared at 50 ppm of GA3. Comparing its rates with different seedpriming, they were relatively higher with KNO3 than those with PEG6000. In protein expression patterns between before thegerminating and after the germinating of seeds, more and clear bands were appeared in the seed after the germination com-pared to those before the germination of seeds, especially 10~20kDa. These results showing more and clear bands weremore clearly appeared in Gwang-Ju compared to Je-Cheon. Comparing the protein expression with plant growth regulatorsand seed primings, GA3 was better expression than those with Kinetin and KNO3 was better than those with PEG6000. Moreand clear bands were closely related to the germination rates of seeds and more detailed studies would be required.

Characteristic of seed for Sageretia thea fruits collected from the habitat of harvest season in Jeju and theirgermination ratio in different temperatures were considered. The average weight was 0.2g, average diameter was 7.2㎜,average length was 6.5㎜, and size distribution range was 5.1~10.0mm. The number of seeds per fruit was 1.8, and 1000grain weight was 7.77g with diameter of 3.7㎜ and thickness of 1.7㎜ in size. The fruit maturation was investigated to befrom April 27 to June 1, when the best maturation period was about a week, May 11 to May 18. Also, the fruits grown onMay 4 to May 11 were seen to have the bigger in transverse size and weight with a tendency of the earlier maturation datehas the greater the number of seeds. S. thea seeds pretreated for 24 hours at 50℃ were not germinated, while most of thosepretreated for 24 hours at 4℃ were successfully germinated at any degree of temperature (except at a temperature of 10℃).Particularly, the highest germination rate of 55% was made at 15℃, and plumule and radicle were best grown within thetemperature range of 25℃.

This study was conducted to investigate the quality of seeds, the germination rates and the days required for germination, to examine the patterns of protein expressions during the germination and to improve the techniques of managing and storing seeds and viability of the seeds of Lithospermum erythrorhizon Sieb. et Zucc. After collecting and harvesting seeds, they were classified to white and brown colors of seed coat through testing their seed size, weight, and quality. The germination rates, the days required for germination, and the protein expressions were examined with different colors of seed coats, storing temperatures and durations by treating the different plant growth regulators and primings. One hundred seed weight of white color was heavier about 1.17 g than those of brown one about 0.81 g. The germination rates in white color of seed coat was higher, 3.05 ~ 5.75%, than those in brown one. Its rates were decreased with getting longer in storage durations. There was no big differences on germination rates between storage temperatures. The plant growth regulator of GA3 and Kinetin was affected to improve the seed germination. GA3 increased the seed germination clearly at 25 ppm level, while kinetin increased it gradually from 25 to 100 ppm levels. In germination by seed primings, PEG6000 made higher germination rate with increasing their levels, whereas KNO3 increased the germination until 100 mM level and then decreased it with 200 mM unlike PEG6000. The protein expressed during the seed germination were appeared more and clearer bands in the seed after germination, especially 20 ~ 30 kDa, compared to those in the seed before germination. These results showing more and clearer bands were positively related to the germination rates which were different by seed colors, storage temperatures and durations, and plant growth regulators and primings.

This study was investigated to evaluate germination rate of Astragalus membranaceus B. in Korea as affectedby storage temperature, germination temperature and storage period of seed. The highest germination rate was obtainedfrom condition of 25℃ in germination temperature. Seeds were stored at −20℃ and 5℃ for 8 weeks has showed higher ger-mination rate than one at room temperatures. The germination rates showed significantly difference by harvested year of2010, 2011 and 2012. The seed of A. membranaceus in harvested year of 2011 and 2012 had germinated well. On the otherhand, seeds in harvested year of 2010 were not nearly germinated. Consequently, the longer storage period after seed har-vest lower germination rate and seed vigor as well.

This study was carried out to compare the characteristics of seed germination and the first stage of growth in Cynanchum wilfordii (Maxim.) by different light conditions such ass fluorescent light, dark and light emitting diode (LED). There was not much difference from the germination rate of C. wilfordii (Maxim.) in different light conditions for 10 days. The highest of germination rate occurred over 91.11 percentage by LED red condition at 26℃. Also mean germination velocity and promptness index were represented the highest results of 2.3 ea/day and 52.67 under red light, respectively. But mean germination time under both LED red and blue light was represented low data that it takes over three days for germinating of seed. Even though handling both LED red and blue lights, the germination uniformity was not constant. These results may help our understanding of variations in germination characteristics for C. wilfordii (Maxim.) seeds treated under different light conditions.

The objective of this study was to evaluate the quality characteristics of mungbean starch gels that were prepared with different concentrations (0, 0.5, 1.0 and 1.5%) of peach seed powders (PSP), which exhibit antioxidant characteristics. Mungbean starch gel samples were prepared and subjected to quality characteristics such as moisture content, general components, color, texture profile analysis, total polyphenol contents, DPPH radical scavenging activity, and sensory qualities. The L-value and the a-value for color decreased significantly, whereas the b-value increased significantly as the PSP concentration increased (p<0.05). In the texture profile analysis, the mungbean starch gel with 1.5% PSP showed significantly lower degrees of hardness, cohesiveness, springiness, gumminess and brittleness (p<0.05). The total polyphenol content was highest in the 1.5% PSP to which mungbean starch gel was added, which also showed a higher than 70% DPPH radical scavenging activity level in a dose-dependent manner (p<0.05). In the sensory test of the mungbean starch gel, its sensory scores for flavor and taste were highest in the 0.5% PSP to which mungbean starch gel was added.
