春播与复播油葵籽粒形成期生理特性的初步研究

Preliminary Study on Physiological Characteristics of Spring Sowing and Multiple Cropping Oil Sunflower at Filling Stage

鉴于目前新疆北疆地区复播油葵存在的一些问题 ,对比春播与复播油葵灌浆期的各项生理指标 :籽粒形成与灌浆速率 ,油份积累的变化规律 ,群体光合强度及同化物的运转。结果表明适当改善灌浆的环境条件 ,增强籽粒的灌浆活性及成油率 ,复播油葵更有进一步丰产。

In view of the present problem that multiple cropping oil sunflowers exist,we contrast some physiology quota of the spring sowing with that of multiple cropping oil sunflower at filling stage:taking shape and filling of seed;varying of oil accumulation;canopy photosynthesis intensity and the assimilation operation.The result indicates:appropriate improvement of the environmental condiation of filling stage,strengthen the filling activity of seed and oil rate,multiple cropping oil sunflower exists potentiality of gaining further bumper harvest and high oil.\;
