摘要
以引自新疆的大果沙枣和尖果沙枣两个树种为试材,对其叶片、花、果实、种子等植物学特征进行了调查分析。结果表明:两个沙枣品种在果实、叶基形状,叶片、叶柄、花柱、花柄及花药长度方面差异显著,可作为两种沙枣区别的主要标志,为今后区分识别与利用两种沙枣提供依据。
Elaeagnus moorcroftii Wall. ex Schlecht. and Elaeagnus oxycarpa Schlecht. introduced from Xinjiang Province were tested for the botanical characters of leaves, flowers, fruits, seeds and other organs. The results show that there were significant differences in the fruit and leaf base sharp, and the length of leaf, petiole, style, floral shoot and anthers length between E. moorcroftii and E. oxycarpa, which provided important characters for distinguishing these two species. This investigation could provide certain evidence for identification and utilization of the two Elaeagnus spp. in the future.
