| 摘 要： | 低温冷冻真空干燥处理五月慢油菜（小白菜）种子１或２ｄ（天）后，种子含水量可降到２．９％或１．９％，在２０℃温度下密封贮存９４个月后，种子发芽率仍能维持在９８％以上的贮初水平，冷干２ｄ（天）的处理比冷干１ｄ（天）的处理效果好。同时实验结果还表明经低温冷冻真空干燥处理后，种子的生活力和种子活力都比对照（４％含水量）的贮藏效果好

| Abstract: | This inverstigation aimed to determine whether Freeze dried storage improves the longevity of Chinese cabbage ( Brassica rapa ssp. Chinensis ) seed. By using Freeze drier to treat seed for 1 day and 2 days,the seed water content was 2.9% and 1.9%,respectively. After stored at 20℃ for 94 months,ssed germination remains as high as initial level. The effect of treat 2 is better than treat 1,the treat of Freeze dried is better than CK(4% Wc%). |
