盐胁迫对不同菠菜品种发芽率及生理特性的影响
Effects of Salt Stress on Germination Rate and Physiological Characters of Different Spinach Varieties
摘要
Abstract
Using 3 spinach cultivars,Fulaite,Huangkang and Bolaiyin,as materials,the effects of dif-ferent concentrations of NaCl (0,20,40,60,80 mmol /L)on germination rate,leaf area,chlorophyll con-tent,photosynthetic parameters,activities of antioxidant enzymes,proline and soluable protein contents were studied.The results showed that 3 spinach cultivars all exhibited the highest germination rate,chlorophyll content,superoxide dismutase (SOD)and peroxidase (POD)activities under 20 mmol /L NaCl treatment. With the increase of NaCl concentration,the leaf area decreased,while the proline content increased,among which,the highest content appeared in Bolaiyin with the biggest change amplitude.The soluble protein con-tent had the similar tendency with that of proline.The net photosynthetic rate got the highest under 20 mmol /L NaCl treatment.The transpiration rate and stomatal conductance reduced gradually with the increase of NaCl concentration.Above all,lower NaCl concentration could promote spinach growth,and Bolaiyin showed higher salt resistance compared with the other two cultivars.关键词
