| 英文摘要 | To investigate the effects of exogenous lanthanum (La) on Alternanthera philoxeroides (Mart.) Griseb under perchlorate stress, changes in the growth and physiological parameters were investigated in solution culture experiments under controlled conditions. Different concentrations of La (NO3)(3) were used in our study. It was shown that 0.1 and 0.5 mg/L La3+ alleviated the inhibition effect of perchlorate on A. philoxeroides, including relative growth yield, dry weight of different organs, leaf area and root activity. And La3+ prevented decline in the relative chlorophyll content and chlorophyll fluorescence parameters including F-v/Fm,Fv'/F-m',Phi(PSII) and ETR induced by perchlorate stress. Moreover, 0.5 mg/L La3+ showed an optimal mitigative effect, while excess La3+ (5.0 mg/L) led to synergistic effect on stress. Correlation analysis revealed a significant positive relationship between growth indexes and the chlorophyll fluorescence parameters, root activity and relative chlorophyll content (p<0.05). The results suggested that appropriate concentration of La3+ could effectively alleviate growth inhibition and injury of A. philoxeroides caused by perchlorate stress, and the mitigative effect of La3+ might be achieved by improving root activity, maintaining chlorophyll content and promoting photochemical efficiency of photosystem II of A. philoxeroides under perchlorate stress. |
