Comparative Study on GA Treatment to Promote the Seed Germination of Different Eggplant Varieties

Eggplant(Solanum melongena L.) is the world’s fourth largest vegetable crop,but the dormancy phenomenon is common.This experiment selected 7 varieties of eggplant,which are widely used in the production at present in Beijing area,including Jing Qie No.5,Jing Qie No.10,Jing Qie No.3,Jing Yan No.2,Damingqie,Kuaiyuanqie and Jingqie No.1.After sterilization with 1.2% hydrogen peroxide for 5 minutes,the seeds were soaked with 300 mg/L GA for 30 minutes,and the test temperatures were in the range of 20-30 ℃.Experimental results showed that the germination rate of GA treatment increased the maximum of 18%,indicating GA treatment can promote seed germination.Meanwhile,GA treatment can improve the speed of germination of eggplant,and shorten germination days,so that it is conducive to rapid germination of seed after sowing.
