[Objective] To study on the effects of NaCl solution on the physiological indices of Polygonum lapathifolium L. seedlings. [Method] Taking P. lapathifolium seedlings as the research materials, the contents of chlorophyll, soluble sugar, and MDA were detected under different treatments of NaCl solutions (0, 50, 75, 100, 125, 150 mmol/L), so as to determine the salt-resistant ability of P. lapathifolium. [Result] When NaCl concentration was less than 125 mmol/L, chlorophyll content increased as the NaCl concentration enhanced. But MDA content reduced significantly; and soluble sugar content firstly enhanced and then fell. When NaCl concentration was 150 mmol/L, chlorophyll content was significantly less than that in the CK; MDA content was significantly greater; and soluble sugar content was also greater than that in CK. [Conclusion] Within the range of 0-150 mmol/L, stress of NaCl on P. lapathifolium would start the self-defense mechanism of P. lapathifolium in order to adapt to the environmental stress. Thus, P. lapathifolium had certain salt-resistant ability.
