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 $GA_3$ and Kinetin was affected to improve the seed germination. $GA_3$ 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 $KNO_3$ 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.
