초록

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 temperaturesand 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 comparedto those before the germination of seeds, especially 10 ~ 20 kDa. 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.
