骆驼蓬属种子微形态及其生态学与分类学意义

A STUDY ON THE SEEDS MICRO-MORPHOLOGICAL CHARACTERISTICS OF PEGANUM FROM CHINA NORTHWEST AND ITS TAXONOMIC AND ECOLOGICAL SIGNIFICANCE

摘要: 报道了光镜及扫描电镜下,西北地区骆驼蓬属(Peganum L.)3种、9个地方居群的种子微形态特征。结果表明:该属植物种子微形态特征在种的水平上具有分类学意义;同种的不同地方居群间基本类型一致,但也存在一定程度的变异。其种子微形态与萌发有关。

Abstract: The micro-morphological characteristics of the seeds of 3 species and 9 populations of Peganum from China northwest under microscope and scanning electronmicroscope were reported. The results show that the seeds micro-morphological characteristics have taxonomic and significance at species level and there is little variation existing in different populations.
