Figure 1. Photosynthetic characteristics in stems of invasive plantMikania micrantha and three native plants on 20 days after
defoliation. (a) Net photosynthesis at PPFD of 800 μmol
m-2 s-1. (b) Day respiration. (c)
Gross photosynthesis. (d) The increase of gross photosynthesis in the
defoliation group relative to control group. Different letters above
bars indicate statistical significance (P < 0.05).
Abbreviations: Mm, Mikania micrantha ; Pn, Pharbitis nil ;
Ps, Paederia scandens ; Pl, Pueraria lobata ;P n, net photosynthesis;R d, day respiration; P g,
gross photosynthesis. △P g, the difference ofP g between the defoliated plants and normally
growth plants.
Figure 2. Chlorophyll contents, Fv/Fm and ETR in stems of invasive plantMikania micrantha and three native plants on 20 days after
defoliation. (a) Transverse section of the stems. (b-d) Chlorophylla , b and a /b ratio. (e) Maximal quantum
yield. (f) Light response curve of electron transport rate. (g) Electron
transport rate at PPFD of 1200 μmol m-2s-1. Different letters above bars indicate statistical
significance (P < 0.05). Abbreviations: Mm,Mikania micrantha ; Pn, Pharbitis nil ; Ps, Paederia
scandens ; Pl, Pueraria lobata ; Fv/Fm, maximal quantum yield;
ETR, electron transport rate; PPFD, photosynthetic photon flux density.
Figure 3. Growth rate (a) in stems of invasive plant Mikania
micrantha and three native plants after defoliation and the survival
rate (b) on 30 days after defoliation. Abbreviations: Mm, Mikania
micrantha ; Pn, Pharbitis nil ; Ps, Paederia scandens ; Pl,
