对黄瓜单性结实品系P 116 8和非单性结实品系UP 3315进行授粉和不授粉处理 ,P 116 8在不授粉的情况下 ,仍具有较好的结实性能 ,其单果质量、果长和果实体积均接近于授粉后生长的果实 ,非单性结实品系UP 3315在不授粉的情况下幼果在花后 3d(天 )就停止发育 ,不能形成产量。随着果实的生长发育 ,果实内碳、氮含量迅速增加 ,花后单果可溶性总糖和蛋白质含量与单果质量呈正相关关系 P 116 8 and non-parthenocarpic lines UP 3315 of cucumber were tested for non-pollination and non-pollination. P 116 8 still had better seed-setting performance without pollination. The fruit quality, fruit length and fruit The volume of the fruit was close to that of the fruit after pollination. The fruit of non-single-stranded UP 3315 stopped growing 3d (days) after anthesis and could not form the yield. With the growth and development of fruit, the content of carbon and nitrogen in fruit increased rapidly. The content of total soluble sugar and protein in post-anthesis fruit had a positive correlation with the fruit weight
