P_2西瓜采种植株的生理性状与种子产量、质量的关系

Relationship between plant Physiological Character and Yield and Quality of P_2 Watermelon Seed

采种植株生理性状与种子产量相关,但与种子质量无关。其中,雌花序位置与单瓜种子总重量和单瓜种子总数(r=0.48,0.60),座瓜位置与单瓜种子总数(r=0.65),座瓜叶数与单瓜种子总重量和单瓜种子总数(r=0.52,0.63),单瓜种子总数与单瓜种子总重量之间(r=0.94)呈正相关。而雌花序位置、座瓜位置、座瓜叶数和单瓜种子总数均与百粒重呈负相关(r=-0.58,-0.62,-0.56,-0.48)。但种瓜直径与种子产量之间无明显关系。

The plant physiological charactor was closely correlated whih that of seed yield but not with that of seed quality. A positive correlation was found between: the location of female flower head and the seed yield per fruit and the seed number per fruit (r =0. 48 and 0. 60 respectively), the location of setting fruit and the seed number per fruit (r = 0. 65), the leaf number of setting fruit and the seed yield per fruit and the seed number per fruit (r = 0. 52 and 0. 63 respectively), the seed number per fruit and the seed yield per fruit (r = 0. 94). A negative correlation was demonstrated between: the location of female flower head, the location of setting fruit, the leaf number of setting fruit and the seed number per fruit with 100-seeds weight (r=-0. 58, -0- 62, -0. 56 and -0. 48 respectively) . However, there was no correlation between the diameter of fruit and the seed yield per fruit.
