摘要
为了打破茄子种子休眠，采用ＨＣｌ、Ｈ２Ｏ２、ＧＡ３、６－ＢＡ及变温处理等技术对采收晒种前及播种前的种子进行预处理，共计３５个组合．试验结果表明，ＧＡ３效果最佳，其次为６－ＢＡ及Ｈ２Ｏ２，ＨＣｌ处理效果也较好，但应注意药剂含量与时间．其中体积分数为０．０１的ＨＣｌ处理０．５ｈ、０．００５的Ｈ２Ｏ２处理０．２５ｈ，ＧＡ３以８０ｍｇＬ－１处理０．２５～０．５ｈ，６－ＢＡ以２０ｍｇＬ－１处理０．２５ｈ的效果最好，变温处理也有同等效果．总体上看，处理效果以晒种前比播种前好，但两者未达到显著差异．
The HCl, H2O2, GA3, 6BA and poikiothermal treatments were conducted to break dormancy of eggplant seeds. The seed pretreatment were carried out in 2 periods, after harvest ( before sun dry) and before sowing, including 35 treatments in all. The results showed that GA3 was more effective than others, followed by 6BA and H2O2. HCl had effect but was affected by volume fractions and duration for treatment. The optimal volume fractions and duration for treatment were 0.01 HCl for 0.5 h, 0.005 H2O2 for 0.25 h, 80 mg·L-1 GA3 for 0.25-0.5 h, 20 mg·L-1 6BA for 0.[KG-4]25 h. Poikiothermal treatment had the same effect. Pretreatment before sun dry seemed to be better than before sowing, but there was no significant difference.
