油菜品种硼素营养的基因型差异

GENETIC VARIATION OF BORON NUTRITION IN RAPESEED VARIETIES

在水培试验中，研究了不同油菜品种的硼素营养特性。在高硼条件下．不同品种的含硼量为新油杂７号＞伊犁野油菜＞泽荣８３，在低硼条件下为伊犁野油菜＞泽荣８３＞新油条７号。施硼明显增加各油菜品种的单株结角数和每角粒数，提高单株生产力。其中，新油杂７号增产潜力最大，泽荣８３与伊犁野油菜次之。

A solution culture of three rape varieties were employed to study the difference of their boron nutrition. The results showed that double-low hybrid Xinyou No 7 was most sensitive to B-deficiency followed by Zherong 83 and Yili wild rape. Boron applied could significantly improve pods per plant and seeds per pod,and the potential of yield was Xinyou No 7>Zherong 83 and Yili wild rape.
