Leaf Length and Ratio of Dry Weight to Fresh Weight: Effect on Resin Production Capacity of Pinus massoniana
摘要
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.关键词
