黄果西番莲冬果果实生长发育动态观测

以‘黄金’黄果西番莲为材料,研究黄果西番莲冬果果实生长发育规律,结果表明：黄果西番莲冬果果实生长发育时间共计84d,质量增长曲线呈单“Ｓ”型,果实质量快速增长时期为谢花后14-21 d;果实纵径和横径增长曲线基本相同,均呈单峰曲线,果实迅速膨大时期为谢花后21 d,果实横径生长稍大于纵径生长,果实由椭圆形逐渐变为近圆形;谢花后35 d,果腔内产生果汁,果汁可溶性固形物含量变化曲线呈单“Ｓ”型,可溶性固形物含量迅速增加时期为谢花后56-63 d。

Fruit growth and development dynamic observation of Passiflora edulis var. fiavicarpe Degener in winter

The winter-fruit growth and development rules of Passiflora edulis var. fiavicarpe Degener in winter was studied.The result showed that the winter-fruit maturity needed 84 days and its weight growth presented single "S-shape" trend, the growing top of which was at 14-21 days after bloom;the fruit length and diameter growth curve of the fruit was substantially the same ,both of which showed single peak curve.and the determining fruit expansion was at 21 days after bloom,and the fruit length growth was slower than that of diamete,so the fruit shape gradually changed from oval to circle;the fruit juice comed to being at 35 days after bloom,and the soluble soled content curve presented single "S-shape" trend, the growing top of which was at 56-63 days after bloom.
