摘　　要：为给油茶优良无性系的高效经营及加快推广应用提供技术支撑,对GLS高产无性系油茶幼林始产期的生殖生长特性及产量结构特征进行了静态与动态分析。结果表明试验林始产期的林分生殖生长分化程度逐年降低,林分株间产果量差异逐年减小,产量结构变化显示低产株数逐年减少高产株数逐年增多的特点,立地条件和幼林始产期的经营水平明显影响着群体产量结构与林分产量。In order to offer technical support for efficient management and speeding up extension and application of fine clones in Camellia oleifera, characteristics of reproductive growth and yield structure of GLS clones young plantation in C. oleifera were researched at the beginning of bearing period by static and dynamic analysis. The results indicated that differentiation degree of reproductive growth of the forest stands and yields between individual plant were decreased year-by-year at the beginning of bearing period; changes of yield structure showed the feature that the number of low yield plants was decreased and the number of high yield plants was increased year-by-year; site condition and management level at the beginning of bearing period have influence on yield and yield structure of the forest stand.
