摘　　要：花丝受精能力的强弱与维管组织的形成及其功能的强弱密切相关,特别是与韧皮组织的功能密切相关。当韧皮部的筛管、伴胞分化完成后,花丝即具有受精结实能力。当维管组织的功能丧失后,花丝丧失活力。Capability of silks receiving pollen grains was interrelated to the forming and functioning of vascular tissues,especially the phloem' function.Only when primary phloem including sieve tubes and companion cells had formed,silks had the capability of receiving pollen grains.When phloem vascular tissues withered and lost its func-tion,silks would also lose its vigor in the end.
