| 摘 要： | 在甘肃省临泽县黑河中游的中国生态系统研究网络临泽内陆河流域研究站试验区对沙枣花粉育性、花粉-胚珠比(P/O)、花粉活力与寿命、花粉储存物类型等进行了观测。结果表明,沙枣花粉为全育的淀粉型花粉；晴天时，花药散粉后6 h内，花粉活力维持在90%以上；雨天时，花药散粉后，花粉活力即低于3%；三瓣花、四瓣花单花产生的花粉量无显著性差异，P/O分别为15 250±1 497、14 143±1 438。

| Abstract: | Pollen fertility,pollen/ovule ratio,pollen viability and longevity,and pollen histochemistry of Elaeagnus angustifolia were determined in the Linze Inland River Research Station in the middle reaches of Heihe River in Northwest China.The pollen of E.angustifolia is of starch type.The pollen viability is higher than 90% within the 6 hours after anthesis on sunny days and lower than 3% at the beginning of anthesis in rainy days.No difference in the pollen production of single flowers is found between different flower morphes(three or four petals).The pollen/ovule ratios of the two morph flowers are 15 250±1 497,14 143±1 438,respectively. |
