| 摘 要： | 为揭示不同分布区文冠果种实性状与生态因子之间的关系,以7个群体的文冠果植株为研究对象,对13个种实性状进行观测。采用相关性分析、回归分析等方法,明确影响文冠果种实性状的主导生态因子及其作用规律。结果表明,不同分布区文冠果种实性状差异均极显著(P<0.01),单位投影面积种子产量、结果数、单果质量等产量性状的变异系数较大,果实纵径、果实横径、种子纵径、种子横径等种实形态性状变异系数较小。种实性状受多个主要生态因子共同作用,且与各因子间存在显著线性关系。综上所述,文冠果种实性状呈现明显的地理变异规律,生态因子对文冠果的表型性状影响显著。

| Abstract: | In order to clarify the relations between fruit and seed characters of Xanthoceras sorbifolium and ecological factors,13 fruit and seed characters of X.sorbifolium individuals in seven populations were observed.Correlation analysis and regression analysis were used to reveal the dominant ecological factors that affected fruit and seed characters and the function rules.The results showed that there were extremely significant differences( P <0.01)in fruit and seed characters among different populations.The relatively high variation coefficients were observed in yield characters,including seed yield per unit projective area,fruit number and single fruit weight.While the relatively low variation coefficient occurred in fruit and seed form characters including fruit length,fruit width,seed length and seed width.Fruit and seed characters were affected by several major ecological factors,and there were significant linear relationships between fruit and seed characters and those ecological factors.In conclusion,there is an obvious geographical variation pattern for fruit and seed characters,and ecological factors significantly affected the characters of X.sorbifolium . |
