新疆野巴旦杏天然居群叶片性状表型多样性研究

Study on Phenotypic Diversity of Morphologic Characteristics of Amygdalus Ledebouriana Schlecht.Leafs in Xinjiang

对中国新疆野巴旦杏分布的5个自然群系区采集的野巴旦杏叶片进行取样测定,分别测定叶片3项形态指标,结果表明:各指标在同一群系不同株间差异显著,野巴旦杏叶片形态在群系间和群系内存在广泛差异,其中:群系内叶片长、叶片宽及叶片长宽比等3个性状差异均达极显著水平F值分别为19.1637、14.3371及6.5426群系间叶片长、叶片宽及叶片长宽比3个性状差异均达极显著水平,F值分别为11.8400、3.6932和7.7049。根据3个性状的平均,群系间的方差分析占总变异的11.18%。群系内的占46.17%,机误占42.65%。野巴旦杏叶片3个性状群系间的表型分化系数平均为19.14%,而群系内的平均表型变异占80.86%,表明群系内变异是野巴旦杏叶片表型变异的主要来源。

The three morphologie characteristics of leaves were investigated in five location in China Xinjiang. It showed that there are significant differences among morphologic characteristics within population. There was significant differences of leaf characteristic within population and F value was 19. 1637, 14.3371 or 6.5426 within population and 11. 8400,3.693 2 or 7. 704 9 among population, respectively. Based on the average of 3 characters,percentage of variance portion among population and within population was 11.18% and 46.17% and the errors were 42.65%. Phenotypic differentiation among population and within population was 19.14% and 80.86%,The result suggested that the phenotypic variation within population was the main component of the variation in this species.
