【摘要】 PP333对CPI86134具有抑制营养生长、增加有效分枝数和有效结荚数、促进生殖生长的作用。CPI86134植株体喷施不同浓度多效唑药剂后,对叶片的N含量有明显的影响,叶片叶绿素含量随处理浓度的变化规律是:CK<400<50<200<100 ppm,对光合速率的影响规律与叶绿素含量相一致;PP333处理可以提高CPI86134的种子产量和品质。缩短收种时间,提高收种经济效益。
【Abstract】 PP333 can prohibit CPI86134(C. rotundifolia)’s nutritional growth, promote its generative growth and so on. Under the controlling of different consistence of PP333, The effect of the content of nitrogen was evident, the changes of the content of chlorophyll of CPI86134’ s leaves were: CK<400<50<200< 100 ppm,the results of the changes of photosynthetic rate were as the same with the content of chlorophyll. So the experiment showed that spraying PP333 can greatly increase the quantity and the quality of the CPI86134’s seeds, decrease the reserve seeds time and cost of seeding.
