乙烯利对西胡芦形态、性别和产量的影响

用一系列浓度梯度(Oppm,100ppm,150ppm,200ppm,250ppm)的乙烯利水溶液喷施西葫芦幼苗叶片,均可使其植株矮化、叶面积缩小、叶色深绿。且随乙烯利处理浓度的升高,此现象呈相应梯度变化。乙烯利处理能使西葫芦雌花开放时间提早且数目增加,早期产量增加显著,总产量也明显提高。其中以100-150ppm处理组的增产效果最佳。

THE EFFECTS OF ETHREL ON PRODUCTION,MORPHOLOGY AND SEX CONTROL IN CUCURBITA PEPO

When we sprayed the seedling leave of Cucurbita pepo with different concentrations of Ethrel watersolutions Oppm,100ppm,150ppm,200ppm and 250ppm,the plants of Cucurbita pepo became shortened,the leaf area lessened and,the leaf colour darkened,and the more concentrative of Ethrel water solution,the more obvious of the change.When a plant of Cucurbita pepo was treated with Ethrel its female flowers came into bloom early andthe number of its female flower increased clearly.Therefore,the early stage production of Cucurbita pepoincreased obviously,so did the total production.In all groups the results showed that the increased pro-duction of the Cucurbita pepo was the best in 100-150ppm.
