Abstract
To study the effects of exogenous proline on seedling growth,photosynthesis and photosynthetic fluorescence characteristics in the leaves of melon under salt stress,two melon cultivars(Cucumis melo L.cv.Yuhuang and cv.Xuemei) with different salt tolerances were investigated in a nutrient solution culture system.The results showed that: ① Exogenous proline ameliorated the adverse effects of salt stress on plant growth,improved the chlorophyll a,b and total chlorophyll contents.② Salt stress markedly decreased the net photosynthetic rate(Pn),stomatal conductance(Gs),intercellular CO2 concentration(Ci) and water use efficiency(WUE).Exogenous proline markedly increased the Pn,Gs,Ci and WUE of Xuemei melon seedlings under salt stress.③ Salt stress significantly decreased PS Ⅱ actual fluorescence(Φ PSⅡ) and photochemical quenching(qP) of Xuemei which were raised by exogenous proline application,however exogenous proline couldn't changed the maximal quantum efficiency of PSⅡ photochemistry(Fv / Fm) and qN of two melon cultivars under salt stress(P 0.05).It is concluded that exogenous proline could alleviated the injury of melon seedlings under salt stress through improving the photosynthesis,however,these effects were cultivar specific.
