摘 要:茄子砧木‘托鲁巴姆’种子小、发芽困难,为促进其萌发、提高发芽率,选用KNO_3、CaCl_2、NaCl、GA_3对茄子砧木(‘托鲁巴姆’)进行处理,研究回干与不回干对药剂处理‘托鲁巴姆’种子活力和萌发的影响。试验结果表明,GA_3处理后对提高‘托鲁巴姆’种子萌发能力及种子的活力指数作用最强,GA_3处理后种子发芽指数、活力指数分别达21.39、160.84,较CK分别提高了37.59%、118.50%,且回干与不回干效果差异不显著,药剂处理后可直接播种;回干可以显著促进KNO_3、CaCl_2、NaCl处理效果的提升,其中KNO_3促进作用较强,发芽指数、活力指数分别达15.68、136.68,较CK分别提高了14.86%、42.35%,CaCl_2、NaCl作用没有显著差异,发芽指数分别为15.76、16.09,活力指数分别为124.47、124.38。The seeds of eggplant rootstock ('Torvum') are difficult to germinate. In this study, the primed seeds were used as materials, the effects of different priming methods (KNOz, CaCl2, NaCl, GA3) and dehydration or not on vigour and germina- tion of 'Torvum' seeds were investigated. The results showed that the seeds germination ability (21.39) and seeds vigor in- dex (160.84) were significantly improved under GA3 treatment, which were 37.59% and 118.50% higher than CK respec- tively. Seeds germination ability and seeds vigor index were not affected by dehydration, the seeds could be sowed di- rectly after GA3 treatment without dehydration. The efficiencies of KNO3, CaCl2 and NaCl treatment could be promoted by de- hydration, and KNO3 exhibited the best effect on the germination index(15.68) and vigor index(136.68), which were 14.86% and 42.35% higher than CK respectively. There was no significant difference between CaCl2 and NaCl treatments, the germi- nation indexes were 15.76, 16.09, and the vigor indexes were 124.47 and 124.38 respectively.
