Abstract

Galinsona parviflora (Asteraceae) is a widespread annual weed that is invasive, colonizing new ground where it is able to persist. We studied the biomass structure of the G. parviflora population at the module level by using the methods of field plot investigation and weighing at 10 sample plots. Modular biomass was calculated and used for analysis of relationships between various modules. The results show that there was a positive correlation between plant height and modular biomass, between stem biomass and root biomass, stem biomass and capitulum biomass, aboveground biomass and underground biomass, and lastly, stem biomass and leaf biomass. The preferred model which measured all the relationships was a power function model with absolute coefficients(R2) ranging from 0.6303 to 0.9782.
