通过对引进 4个意大利扁桃品种花粉的形态观察及相互间的人工授粉试验表明 ,扁桃花粉形态多呈圆形 ,少量呈三角形 ,大小在 2 4 .7～ 2 5.9μm× 2 2 .6～ 2 4 .9μm之间 ,发育饱满 ,花粉发芽率以 1号最高 ,为68.8% ;3号最低 ,为 56.5%。从授粉组合中看出 ,1号可用 2、4号授粉 ,2号可用 1、4号授粉 ,3号可用 1、2、4号授粉 ,4号可用 1、2号授粉 Through the morphological observation and artificial pollination experiments on four Italian almond varieties, we found that the morphology of almond is mostly round with a small amount of triangular shape with the size of 24.7 ~ 29.9μm × 22.6 ~ 2 4. 9μm, full of development, pollen germination rate to No. 1 highest, 68.8%; No. 3 lowest, 56.5%. From the pollination combination we can see, No. 1, No. 2 and No. 4 can be used for pollination, No. 2 can be used for pollinating No. 1, No. 3 and No. 1, No. 2 and No. 4 for pollination,
