【摘要】 用 0 .5mmol/LLaCl3 ,PrCl3 分别浸种处理油松种子 (蒸馏水浸种作对照 ) ,对油松幼芽酯酶同工酶采用聚丙烯酰胺凝胶电泳分离方法分析。结果表明 ,LaCl3 处理能使幼芽产生较多新的酯酶同工酶 ,并使某些酯酶同工酶活性增强。PrCl3 处理使油松种子萌发初期和中期某些酯酶同工酶活性增强 ,而使后期幼芽产生少数新的酯酶同工酶。说明这两种稀土氯化物浸种可通过诱导加强酯酶同工酶活性 ,促进脂库油脂的动员 ,提高种子活力更多还原

【Abstract】 The results showed the LaCl 3 treatment was favorable for the production of more new lipid iso enzyme and strengthen some of the Iso enzymes.PrCl 3 treatment enhanced the activities of some lipid enzymes at the early and middle stage of pine seed germination.更多还原
