本文以８株解析木材料，研究了红皮云杉生长规律。计算分析得出，速生１０年径生长量与占总材积６７．４％的速生２０年材积相关显著，ｒ＝０．７３。在此基础上提出了数量性状相关选择方法。
In this paper, eight analytical wood materials, the growth of red spruce law. Calculation and analysis showed that the 10-year fast-growing diameter growth was significantly correlated with the 20-year fast-growing volume of 67.4% of the total volume, r = 0.73. On this basis, the method of selecting quantitative traits is proposed.
