- 摘要:
- 为促进小粒大豆种子的耐贮性研究,以3个小粒大豆品种为试验材料,研究低温(5 ℃)条件下贮藏年限对小粒大豆种子萌发及幼苗生长的影响。结果表明:随着贮藏年限的增加,小粒大豆种子发芽势、发芽率、相对发芽率及幼苗苗高、根长、幼苗鲜重、幼苗干重等生长性状均呈降低趋势。贮藏4 a的3个小粒大豆种子平均发芽率为53.50%,完全丧失种用价值。不同小粒豆品种耐贮藏能力不同,3个品种中,东农690和吉林小粒6号种子的安全贮藏期为1 a,九芽豆1号耐贮性较好,安全贮藏期为2 a。
- Abstract:
- In order to improve the storability of Glycine gracilis varieties,taking 3 Glycine gracilis varieties as experimental materials, the effects of storage life on seed germination and seedling growth under low temperature(5 ℃) were studied.The results showed that,with the increase of storage life,the germination momentum, germination rate, relative germination rate, seedling height, root length, fresh weight and dry weight of Glycine gracilis decreased.The average germination rate of 3 Glycine gracilis seeds varieties stored for 4 a was 53.50%, which lost the seed value completely.Different varieties of Glycine gracilis varieties have different storability.Among the three varieties, Dongnong 690 and Jilin small-grain 6 soybean had a safe storage period of 1 a, while Jiuya 1 soybean had a better storage tolerance and a safe storage period of 2 a.
