| 摘 要： | 以20个枣品种为试材，测定了花粉萌发率和单药花粉量。结果表明，枣不同品种在同一时期及同一品种在不同花期花粉量和花粉萌发率差异显著，初花期单花药花粉量最多的品种达5556粒，最少的为0。花粉量与花粉萌发率之间无显著的相关性。枣树的单药花粉量在6月中下旬最高，而花粉萌发率在6月中旬出现高峰。发现了无花粉、高含仁率的优异雄性不育新种质JMS3，并进一步证明了JMS1的无花粉性状稳定。 |

| Abstract: | The pollen number per anther(PNPA) and pollen germination rate(PGR) of 20 cultivars of Chinese jujube(Ziziphus jujuba Mill.)were tested.The results showed that PNPA and PGR varied significantly among cultivars and flower buds of same cultivar during flowering stage.PNPA varied from 0 to 5556 among cultivars in the early flowering stage.PNPA was not significantly related with PGR.While PNPA increased to its highest value in late June,and the highest level of PGR appeared in mid-June.An excellent new male sterile germplasm,JMS3(no pollen and high seed rate),was found and the stability of male sterile trait of JMS1 was further confirmed. |
