| 摘 要： | 研究了利用赤霉素包衣对两个黄瓜品种种子发芽、幼苗生长的影响.结果表明,用赤霉素作为激素添加剂包衣特早、露丰黄瓜种子,对2种黄瓜种子的发芽率和发芽势等无显著影响,但显著提高了黄瓜幼苗的下胚轴和叶片长度,显著增加了幼苗下胚轴和子叶的干重,对根干重无显著影响.

| Abstract: | The influence of film coating with gibberellic acid(GA_(3)) on seed germination and seedling growth of cucumber was investigated.The resulted showed that the treatment of film-coating with GA_(3)did not significantly affect germination percentage and germination energy in two cucumber cultivars.However,the treatment coated with GA_(3) increased remarkably the length of seedling hypocotyl and cotyledon and the dry weight of the hypocotyl and cotyledon,and had no significant effect on the dry root weight. |
