摘要:
为深入了解南川木波罗构件种群生物量、比叶面积及叶干物质含量随苗龄叶龄的变化规律,以南川木波罗幼苗(1~5年生)为研究对象,分析其根、 茎、叶等构件种群的生物量、SLA、LDMC差异及动态变化。结果表明:(1)单株生物量随着苗龄增加而增加,且差异达显著性水平;(2)各构件生物量增加的幅度不尽相同,其中枝条生物量增长幅度最大,5年生幼苗与2年生幼苗相比达477.23倍,其余构件生物量为主干>叶>根;(3)枝条和主干的生物量比率总体上呈上升趋势,所占根比率变动较小而叶逐渐下降。表明植物体对各构件生物量投资的不均衡性,主要偏向于枝和主干;(4)SLA随着苗龄的增加呈先上升后降低的趋势,且当年生叶大于1年生叶; 幼苗叶片干物质含量(LDMC)随苗龄增加而增加,且1年生叶均高于当年生叶。
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. nanchuanensis 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 ratio 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.
