野生西瓜开花结实及结籽特性的研究(英文)

Study on the Flowering,Fruiting and Seed Setting Characteristic of Wild Watermelon

[目的]探讨野生西瓜的开花结实、结籽特性。[方法]对野生西瓜的开花结实习性进行了观测,并研究了不同授粉方式(混合花粉授粉、单花花粉授粉和自然授粉)对野生西瓜座果率、单瓜重、单瓜种子数及种子千粒重的影响。[结果]野生西瓜雌花少,座果率低。采用人工授粉虽不能显著提高野生西瓜的座果率,但能显著地提高单瓜重、种子的产量和质量,其中以混合花粉授粉最好。[结论]为提高野生西瓜的制种产量和质量提供了参才。

[Objective] The flowering,fruiting and seed setting characteristic of wild watermelon were discussed in our paper.[Method] The flowering and fruiting habit of wild watermelon were observed,and the effect of different pollination methods（mixed pollination,single flower pollination and natural pollination）on fruit set percentage,weight per fruit,seeds per fruit and thousand-seed weight of wild watermelon were studied in our paper.[Result] Wild watermelon had few female flowers and low fruit set percentage;artificial pollination could not increase the fruit set percentage of wild watermelon obviously,but it could improve weight per fruit,seed yield and quality significantly,and mixed pollination was the best.[Conclusion] Our study could provide reference for the improvement of hybrid seed yield and quality of wild watermelon.
