- Abstract
We investigated the effects of shoot parts (stem and leaf) of B. Pilosa and leaf of Rudbeckia hirta (native specie) on chlorophyll fluorescence in P. multifida gametophyte. The gametophytes exposed to stem and leaf leachates of B. pilosa and leaf leachate of R. hirta decreased the chlorophyll fluorescence parameters than control, except for non-photochemical quenching. The inhibitory effects increased with increasing leachates concentrations of B. Pilosa, exhibiting the greatest inhibition at day 10. However, the chlorophyll florescence of Pteris multifida was lower with R. hirta than with B. pilosa leachates. It was concluded that B. pilosa negatively affected the chlorophyll fluorescence of P. multifida. The leachate from shoot parts of Bidens pilosa reduced the photosynthesis of P. multifida gametophyte. Thus the invasive species leachates may be harmful to native plants.
