茄子种子打破休眠的预处理技术

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．

Pretreatment techniques for eggplant seeds to break dormancy

The HCl, H2O2, GA3, 6 BA 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 GA3 was more effective than others, followed by 6 BA and H2O2. 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 H2O2 for 0.25 h, 80 mg·L-1 GA3 for 0.25-0.5 h, 20 mg·L-1 6 BA 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.
