Abstract:
Under greenhouse conditions,with the leaf,stem,root of potted 1 year wild apricot as the test material,four levels of soil moisture treatment,respectively 100%,80%,60%,40%,under water stress treats 7 days,14 days,21 days later were set and determination of changes of proline,soluble sugar,starch contents,the relative water content,leaf area were studied.The results showed that with increasing of water stress,the proline content of wild apricot seedlings increased,but the accumulation of proline showed decline.The content of soluble sugar in the leaves decreased with the water stress time prolonging,but when the soil moisture content was 40%,the content of soluble sugars in leaves increased.The content of soluble sugar in the stem increased first and then decreased.The leaves and stems of starch content decreased first and then increased with the increasing of water stress,with the extension of stress time,starch content of each level decreased.With the water stress time prolonging and the deepening of water stress,leaf relative water content increased,the stem,root relative water content reduced.But when the soil relative water content was 40%,the relative water content in stem was increased with the deepening of water stress.In short,soil moisture of 1 year wild apricot seedlings was field capacity between 60%～80%.
