MODULE BIOMASS STRUCTURE TRAITS OF THE ALIEN INVASIVE PLANTAGERATUM CONYZOIDES
摘要
Abstract
Ageratum conyzoides is one of the alien invasive plants distributied abroadly in Yangtse river drainage area and the south area of it in China. Biomass structure characteristic and correlation models among different modules ofA. conyzoidespopulation were studied at module level by sampling surveys. Their quantitative analysis and the relation between the characteristics and its invasiveness were also done in this paper. The results showed that the modules biomass ofA. conyzoideswas decreased in the sequence of stem, leaf, root, capitulum, and the biomass proportion of each module to the whole plant biomass was decreased in the same sequence. The biomass of each module had significant positive correlations, and all the correlations could be well expressed by linear model. Stronger phenotypic plasticity of eachA. conyzoides module greatly enhanced its invasive ability, and lower reproductive biomass allocation indicated the pertinence and efficiency for its control during flowering phase.关键词
