摘  要:
为解决土壤盐渍化对番茄种子萌发的影响,以番茄品种"齐达利"为试材,分别用0、0.5、1.0、1.5、10.0、100.0mg/L浓度的ABA溶液处理番茄种子,以期找到缓解盐胁迫效应的合适外源ABA浓度,从而为盐胁迫下种子又快又好萌发提供有效解决方法。结果表明:不同浓度的盐胁迫下,最佳ABA处理浓度为1.5mg/L,在此浓度下种子的发芽率、发芽势、发芽指数及活力指数达到最高值,同时产生的丙二醛(MDA)含量和超微弱发光(UWL)的值也最小。

摘  要:
In order to solve the effect of soil salinity on the germination of tomato seeds,with tomato variety of‘Qidali'as material,the content of ABA of 0,0.5,1.0,1.5,10.0,100.0mg/L were set respectively,the aim was to find out which content was the best to alleviate the salt stress effect.The results showed that the best content of exogenous ABA was1.5mg/L,because in this content the germination rate,germination potential,germination index and vigor index reached the highest value,besides the MDA content and UWL reached minimum value.
