摘要
以胡颓子属(Elaeagnus Linn.)5种落叶植物为试材,对其果实性状进行观测,并运用方差分析、多重比较和系统聚类方法进行了分析。结果表明:种间果实性状存在显著差异,其中果高、果形指数、果质量、果肉率的差异极显著。5种胡颓子属植物中,毛木半夏的果径变异系数最大,其它种以果质量变异系数为最大。聚类分析表明银果牛奶子与江西羊奶子果实性状较相似,较其它3种具有果形指数高、单果质量大、果肉多的性状特点。
Taking five deciduous species of Elaeagnus Linn.as materials,their fruits characteristics were observed,and studied by analysis of variance,multiple comparisons,hierarchical clustering.The results showed that significant difference of fruit characteristics was found among different species,wherein the fruit high,fruit shape index,fruit weight,flesh rate differences extremely were significant.In the five species of plants,E.multiflorafruit diameter variation coefficient was the maximum,fruit weight variation coefficient of other species were maximized.Cluster analysis showed that E.magna and E.jiangxiensi fruit traits were similar,compared with the others,with fruit shape index higher,fruit heavier,more flesh trait characteristics.
