摘 要 ：硼营养不足,油菜植株各器官含硼量均下降,下降幅度因器官而异,而以花器官下降幅度最大。缺硼时,花器发育异常,雄蕊在解剖生理上的异常现象尤为突出,严重时花粉败育,花蕾脱落,甚至出现颗粒无收的现象。花粉败育表现为花粉囊空瘪,核质解体,无孢原组织分化,绒毡层发育异常,小孢子原生质团溢出药壁外等现象。硼营养不足降低了花药

Abstract:The effect of boron nutrition on the seed setting characterics of rapeseed (Brassicanaous L.) were studied though observation of the morphology of the floral organsand analysis of the physiological properties. The results are as follows: (1) Application of boron fertilizer (+B) could greatly increas
