| 摘 要： | 对三江平原3种不同生境下小叶章的主要形态因子进行了测定,结果表明,3种生境下小叶章的形态数量指标表现出极显著的差异。在生境内,典型草甸小叶章的表型性状的平均值在7月份达到最大;在沼泽、沼泽化草甸小叶章中,表型性状的平均值均在8月份达到最大。在生境间,表型性状的平均值由大到小依次为典型草甸小叶章〉沼泽化草甸小叶章〉沼泽小叶章。

| Abstract: | This paper mensurated main morphological factors for the ramets of Calamagrostis angustifolia populations in three vegetation types in Sanjiang Plains of China.The results showed that in the three habitats morphological quantitative index showed significant differences.Within habitats,phenotypic features averages reached maximum values in July in typical meadow;in marsh and marsh meadow,phenotypic features averages all reached maximum values in August.Among habitats,phenotypic features averages from most to... |
