| 摘 要： | 用正交试验方法L9(34)研究了3种植物生长调节物质(IAA、GA3、NAA)以及3种浓度(50、100、200 mg/L)和3种处理时间(浸沾1 s、浸泡1 min、10 min)对银杏高位嫁接成活率与枝梢生长的影响.结果表明:采用IAA和NAA能够提高银杏嫁接成活率,最好组合是A3C2D1,成活率达99.3%,枝梢生长达128.3 cm,而GA3则对嫁接成活率有一定的抑制作用;在银杏嫁接时,IAA对银杏嫁接成活率和枝梢生长影响较大;不同时间的处理,激素对嫁接的效果也不同.

| Abstract: | The effects of different concentrations(50,100 and 200 mg/L) and different time periods(soaking for 1 second,for 1 minute and for 10 minutes) of IAA,GA_3 and NAA on the living rate of top grafting and branch growth of Ginkgo biloba.L were investigated using an orthogonal design L9(34).The results show that IAA and NAA could improve the living rate of top grafting,with the best ratio being A_3C_2D_1,the highest living rate being 99.3% and the branch length being 128.3 cm;but that GA_3 restrained the living rate.Therefore,IAA had an obvious influence on the living rate of top grating and branch growth;however,the effects of exogenous growth regulators changed when used in a different time. |
