NaCl对酸模叶蓼相关生理指标的影响
Effects of NaCl Solution on the Physiological Indices of Polygonum lapathifolium L
摘要
Abstract
[Objective] The aim was to study on the effects of NaCl solution on the physiological indices of Polygonum lapathifoliun L. Seedlings. [Method] Taking P. Lapathifolium seedlings as the research materials, the chlorophyll, soluble sugar, and malonaldehyde contents 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 ≤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. [ Conclusion ] Within the range of 0 - 150 mmol/L, stress of NaCl on P. Lapathifolium would start the self - defense mechanism of P. Lapathifolium to adapt to the environmental stress. Thus, P. Lapathifolium had certain salt - resistant ability.关键词
