摘要: 为探究高产脂马尾松单株特征,通过分析针叶叶长和干鲜重比与马尾松单刀产脂量、年产脂率和年产脂量的关系,研究针叶对马尾松产脂能力的影响。结果表明:叶长与马尾松单刀产脂量、年产脂率和年产脂量均呈正相关关系,相关系数分别为0.881、0.889、0.618。针叶干鲜重比与马尾松单刀产脂量、年产脂率和年产脂量均呈负相关关系,相关系数分别为-0.907、-0.887、-0.618。叶长方差分析中,不同个体存在显著差异(P<0.05),叶长最小的76#对应的3种产脂量均最小;叶长最大的13#、14#(P>0.05)对应的单刀产脂量和年产脂率较大。针叶干鲜重比方差分析中,不同个体间也存在显著差异(P<0.05),干鲜重比最大的76#对应的3种产脂量均最小;干鲜重比最小的13#、14#(P>0.05)对应的单刀产脂量和年产脂率也较大。以上说明,叶长和针叶干鲜重比对马尾松产脂能力有影响。

Abstract: To explore the individual plant characters of Pine Massoniana with high resin production capacity, the effect of needles on the resin production capacity of P. massoniana was studied by analyzing the relationships between leaf length, ratio of dry weight to fresh weight of needles and resin yield of single knife, annual resin rate, annual resin output of P. massoniana. The results showed that there were positive correlations between leaf length and resin yield of single knife, annual resin rate as well as annual resin output. The correlation coefficients were 0.881, 0.889, and 0.618, respectively. The ratio of dry weight to fresh weight had negative correlations with resin yield of single knife, annual resin rate as well as annual resin output. The correlation coefficients were -0.907, -0.887, and -0.618, respectively. In variance analysis of the leaf length, there were significant differences among different individuals of P. massoniana (P<0.05). The three kinds of annual resin output of 76# with the least leaf length were the minimum. 13# and 14# with the largest leaf length (P>0.05) had higher resin yield of single knife and annual resin rate. In the variance analysis of the ratio of dry weight to fresh weight, there were significant differences among different individuals of P. massoniana (P<0.05). The three kinds of annual resin output of 76# with the largest ratio of dry weight to fresh weight were the minimum. 13# and 14# with the least ratio of dry weight to fresh weight had higher resin yield of single knife and annual resin rate. In conclusion, the leaf length and the ratio of dry weight to fresh weight affect the resin production capacity of P. massoniana.
