南川木波罗幼苗构件生物量和叶片特征随年龄增长的变化
Leaf traits and biomass dynamics of modular population in different age classes Artocarpus nanchuanensis seedlings
摘要
Abstract
SLA,LDMC and modules dynamics of Artocarpus nanchuanensis in Chongqing were studied systematically. The results showed that with the increase of A .nanchuanensis seedling ages,the biomass of the single A .nanchua-nensis increased significantly,in which the difference of branch biomass was the biggest,the disparity even to 477.23 times between 2 and 5 age seedlings.The reserved modules biomass generally allocated in the order:branch biomass>leaf biomass>root biomass.The average biomass distribution rate of stem and branch increased generally,leaf rati-o decreased,root ratio changed small.It showed that the chance to receive biomass varied among different modules. Branches had priority over stems in this aspect.With the increase of A .nanchuanensis seedling ages,the trend of SLA change was increased firstly,then decreased,and SLA of one-year-old leave was higher than those of two-year-old.At the same time,LDMC increased generally,but LDMC of current year leave was higher than those of one year.关键词
