| 摘 要： | 对腾冲县6个种群的腾冲红花油茶果实性状变异及性状之间的相关性进行了研究,结果发现腾冲红花油茶果实在种群间、种群内及种群内单株间均存在显著的差异,6个种群果实性状总体变异幅度最大的是单果质量(变异系数为39.01%),其次是果高(变异系数为16.98%)和果径(变异系数为14.59%),变异幅度最小的是果形指数(变异系数为14.57%);单果质量与果高、果形指数、单果鲜籽质量和果径呈极显著的线性相关关系,建立的果径(X1)、果形指数(X4)和单果鲜籽质量(X3)对单果质量的线性回归方程Y=-134.72+3.103 X1+0.47 X3+40.851 X4,可用于单果质量的早期预测.

| Abstract: | Six local cultivated populations of Camellia reticulate in Tengchong County of Yunnan Province were investigated for the variations in their fruit characters,and the correlation among the characters was analyzed.Significant differences were observed in C.reticulate fruit between and within the populations and between different plants within the same population.On the whole for the six populations,fruit weight had the greatest variation,followed by fruit height and fruit diameter,their C.V.(coefficient of va... |
