摘要/Abstract

摘要： 采用电镜扫描技术对蒙古冰草(Agropyron mongolicum Keng)6个天然居群和2个栽培品种的外稃进行了观察分析。结果表明,外稃的微形态特征存在有14种变异类型,具有丰富的多态性;从这些变异的分布格局来看,主要存在于居群内的个体间,居群间的分化并不明显,反映出了居群内变异大于居群间变异的特点。

Abstract: Micro-morphological characteristics of lemmas of Agropyron mongolicum Keng from 6 natural populations and 2 cultivars were investigated using scanning electron microscopy. The results showed that there were 14 kinds of variations on micro-morphological characteristics of lemma surfaces, indicating an abundant polymorphism. As far as the distribution pattern of the variations was concerned, the variations mainly existed within populations, and the differentiation among populations was not obvious. It was proved that the variation within populations was greater than that among populations.

Key words: Agropyron mongolicum, micro-morphological characteristics of lemmas, variation patterns
