Pueraria lobata.
Figure 4. Survival rate, root length and ETR in stems of invasive plantMikania micrantha and three native plants after isolated culture
for 20 days. Abbreviations: ETR, electron transport rate; Mm,Mikania micrantha ; Pn, Pharbitis nil ; Ps, Paederia
scandens ; Pl, Pueraria lobata.
Figure 5. Change of morphology and stomatal behavior in stems ofMikania micrantha at day 20 of defoliation. (a, b) Change of the
stem morphology after defoliation. (c, d) Stoma on the abaxial and
adaxial side of leaves. (e, f) Stoma on stem surface of the control and
treatment. (g) Internode length and diameter of the stem. (h)
Anthocyanin content. (i-l) Stomatal density, length, width and
conductance. Different letters above bars indicate statistical
significance (P < 0.05). Abbreviations: ND,
non-detected.
Figure 6. Change of chlorophyll pigments (a, b), soluble sugar (c),
CO2 assimilation (d, e), electron transport rate (f) and
D1 protein and Rubsico in stems of Mikania micrantha during the
tress of defoliation. CO2 assimilation (e) and electron
transport rate (f) were measured on at day 20 of defoliation. Different
letters above bars indicate statistical significance (P< 0.05). Abbreviations: ETR, electron transport rate;
Pnet, net photosynthesis; Rday, day
respiration; Pgross, gross photosynthesis, PPFD,
photosynthetic photon flux density.
Figure 7. Change of subcellular structure in stems of Mikania
micrantha 20 days after defoliation. (a-f) Transmission electron
microscope image of leaves, control stem and defoliation stem. (g-i)
Change of length, width and lengh:width ratio in the stem after
defoliation. Different letters above bars indicate statistical
significance (P < 0.05). Abbreviations: CP,
chloroplast; CW, cell wall; SG, starch grains.
