摘要:运用变异系数、相对极差、相关分析、巢式方差分析、方差分量比、表型分化系数及层次聚类等方法对腾冲红花油茶12个天然居群种实性状表型多样性进行分析。结果显示:腾冲红花油茶各种实性状在居群间和居群内均存在显著或极显著的差异,且居群内的变异远大于居群间的变异;不同性状变异程度最高的是单果鲜籽质量(42.99%)、单果质量(38.17%)和单籽质量(31.66%),其次是果高(15.69%)和果径(14.01%),果形指数变异程度(13.75%)最小;不同居群变异程度最高的是居群MS1(30.05%),最低的是居群MS3(15.3%),平均居群变异程度为24.83%;不同性状表型分化程度不同,果实形状分化程度最高,果径分化程度最低;除果高和单果质量外其余各性状间均存在显著或极显著的相关性,果径和单果质量的Person简单相关系数高达0.90;果高与经度和海拔显著正相关,与纬度显著负相关,存在明显的地理变异趋势。
Six phenotypic traits were investigated in 12 natural populations of Camellia reticulate f. simplex from west of Yunnan, China, by using nested variance analysis, correlation analysis, variance analysis, phenotypic differentiation co- efficient(VST) and cluster analysis, etc. The results showed that there were significant variance among and within popu- lations ; the variation within populations was much greater than that among populations. The fruit variation coefficients of the seed weight per fruit (42.99%) ,the fruit weight(38.17% ), the seed weight(31.66% ) ,among 4 natural popula- tions had the greatest variance, the fruit height (15.69%),the fruit diameter(14.01%) and the fruit shape index (13.75%) had the least variance, among 12 natural populations MS1 (30.05%)had the greatest variance, the MS3 had the least( 15.3% ) variance, the mean variance, among 12 natural populations was 24.83%. There were significant variance among 6 phenotypic traits except the fruit height and the fruit weight. The Person index between the fruit diame- ter and the fruit weight was 0.90. The fruit height were significant positive relationship with longitude and altitude, but were negative correlation with latitude.
