Meanwhile, the effects of different media on its pollen germination and the growth of pollen tubes were analyzed. The results showed that the optimum media for pollen germination and growth of pollen tubes were 10% sucrose +0.1% boric acid and 5% sucrose + 0.01% boric acid respectively. The self-pollination setting rate of ‘Kuijin' apricot was 4.70%, indicating that ‘Kuijin' apricot was self-incompatible. The reasons for the self-incompatibility of ‘Kuijin' were explored according to its pollen weight and pollen quantity. The results showed that self-pollinate setting rate of ‘Kuijin' apricot was closely related to the length of pollen tubes,but it had no direct correlation with pollen quantity.展开更多
