Abstract: The blooming type of 22 Chinese jujube cultivars, pollen germination percentage of 12 Chinese jujube cultivars, pollen germinating developments of 5 Chinese jujube cultivars, pollen storage of 9 Chinese jujube cultivars and self-fertility percentage of 10 Chinese jujube cultivars were studied. The results were shown as follows:Cuizao, Lajiaozao, Huluzao, Fuzao, Bianhesuan, Junzao, Zanhuangdazao, Hongyan, Wudeng, Jishanyuanzao, Jinzao, Mianzao, Jianzao, Linyilizao, Changhong and Suzao were day blooming type, and Hunanjidanzao, Dongzao, Shulutangzao, Yuechu, Jiantouhui and Tuntunzao were night blooming type. There were great disparity in the pollen germination percentage of 12 jujube cultivars, which were from 1.52% to 74.95%, and the average of which was 34.28%, and the variant coefficient of which was 14.74%. Dongzao was the lowest, however Lajiaozao was the highest. The method of -12℃ dry storage in which the pollen germination percentage was 88.04% of fresh pollen in 6th day and 59.88% of fresh pollen in 10th day was better than that of 2℃ or room temperature. The curves of pollen germination and growth of pollen tube in Chinese jujube were single “S” type. After having been cultivated for 5.5 hours, the pollen germination percentage was not changed, and after 7.5 hours the pollen tube did not grow. It was also found that the percentage of the self-fertility was near the zero in this test.
