[Biomass structure of exotic invasive plant Galinsona parviflora].
Galinsona parviflora is originated from South America, and has an eruptive invasion in Shenyang area. This paper studied the biomass structure of G. parviflora population at module level, with the correlation models among different modules biomass established and quantitatively analyzed. The results showed that the modules biomass of G. parviflora was decreased in the sequence of stem > leaf > capitulum > root, and the proportion of each module's biomass to the whole plant biomass was in the order of stem > leaf > root > capitulum. Stem- and leaf biomass had significant positive correlations with plant height, root biomass and capitulum biomass, and all the correlations could be well expressed by exponential model.
