| 摘 要： | 本研究用不同浓度的GA3、6-BA对柠条锦鸡儿种子进行处理,研究两种生长调节剂对柠条种子及幼苗生长的调控作用.结果表明:GA3可以提高柠条种子的发芽率、发芽势、发芽指数,对柠条的幼苗生长有明显的促进作用,并可大大提高过氧化物酶活性和活力指数;6-BA对柠条的幼苗生长有抑制作用,但可显著提高根系活力和过氧化物酶活性.

| Abstract: | Seeds of Caragana Korshinskii Kom. were soaked in different concentrations of GA 3 and 6-BA solution. The results showed that GA 3 can increase germinative percent, germinative energy and germinative index of Caragana Korshinskii Kom, apparently promote seedling growth, enhance peroxidase activity and vital index. 6-BA decrease the seedling height, but can obviously improve root activity and peroxidase activity of seedlings. |
