通过对几个砂梨新品种的花粉发芽和授粉组合试验结果表明 ,黄金、圆黄、晚秀、华山和水晶梨均自花不实。其中圆黄梨花粉最多 ,花粉发芽率最高 ,是良好的授粉品种 ;华山和晚秀梨次之 ,但华山和晚秀梨之间花粉不亲和 ,不宜互做授粉树 ;黄金、水晶梨花粉极少 ,不能用做授粉树 The results of experiments on germination and pollination of several new sand pear cultivars showed that gold, Yuanhuang, Late Show, Huashan and Crystal Pear were all self-programable. Among them, pollen of Huanghuang pear was the most, pollen germination rate was the highest, it was a good pollination variety; Huashan and Xiuxiu pear were the second, but pollen was not compatible between Huashan and Xiuxiu pear. Very few, can not be used as pollination tree
