| 摘 要： | 利用伐倒木调查资料，研究了天然红松林的生长、结实规律，确定结实盛期为选择优树的最佳时期。相关分析表明，定期结实量与定期结实年数和定期结实平均生长量相关显著。提出了以定期结实年数和定期结实枝平均生长量为标准的优树选择方法。

| Abstract: | Optimum time of plus tree selection in Pinus koriensis plantation was determined according to the natu- ral stand growth and bearing regularity. The correlation analysis of felled timber data showed that significant corre- lation existed among bearing quantity, age, mean increment of bearing branch at regular interval. The great bearing interval was regarded as optimum time, and optimum method for plus tree selection was put forward by the analytical results, |
