Abstract

To investigate the expansion and adaptation mechanisms of the invasive plant Solanum rostratum Dunal in heterogeneous habitats, this study examined populations in two typical habitats—grassland and landfill—in Baicheng City, Jilin Province. Population samples were collected during the maturity period in 2023, and their structural characteristics and biomass distribution patterns were analyzed. Results showed that the proportion of biomass allocated to reproductive organs was significantly higher in the grassland population (53.27% ± 14.12%) compared to the landfill population (46.63% ± 9.97%), while the vegetative allocation showed the opposite trend. The coefficient of variation (CV) for all biomass components was markedly higher in the landfill populations, with the greatest variation observed in fruit mass (CV = 225.68%). These findings reveal that Solanum rostratum Dunal displays pronounced phenotypic plasticity and divergent biomass allocation strategies between habitats. The study provides a theoretical basis for predicting potential invasion risks, monitoring dispersal dynamics, and developing ecological control strategies for this invasive weed in Jilin Province.
