Ca2+和GA3对早白菜苔和薜荔种子萌发的影响

用适宜浓度的钙和赤霉素及其复合溶液浸种处理早白菜苔、薜荔的种子,研究处理对种子萌发的影响.结果表明:(1)低浓度的Ca2 和GA3都可以明显提高种子的活力; (2)Ca2 和GA3的复合溶液对种子的萌发具有更良好的促进作用,各处理间具显著性差异,差异性主要是由GA3引起的; (3)Ca2 和GA3复合溶液处理的淀粉酶活性高于由Ca2 或GA3单独处理的,而且以后酶活性回降的幅度也是复合处理的小于单独处理的.

Effects of Ca2+ and GA3 on Seeds Germination of Cabbage and Ficus pumila

In order to study the effects of Ca2 and GA3 on seeds germination,seeds of cabbage and Ficus pumila were soaked in the solutions of Ca2 ,GA3 and Ca2 GA3 with different concentrations.The results showed as follows:(1) The solutions with lower concentrations of Ca2 or GA3 may enhance the vigor of seeds obviously.(2) The solution composed of both Ca2 and GA3 has better effect on seeds germination.Among these results,the effects of GA3 treatments were more significant than Ca2 .(3) Activity of amylase after seeds treated with the solution composed of Ca2 and GA3 was higher than that treated with solutions of Ca2 or GA3 respectively.The activity of amylase decreased within a smaller range during the third day seeds germinated after treated with mixed solution as compared with seeds treated by Ca2 or GA3 respectively.
