| In order to study the effect of nitrogen and water stress on qualities of rice seedling the water planting and PEG imitated with water stress were carried out in greenhouse.The result showed: root/shoot,NR,root activity and root relative conductance were increased during short period and light water stress;with nitrogen enhancing,root/shoot was reduced.But NR and root activity were opposite; with extending of water stress,root/shoot trended to increase,NR and root activity were decreased.The effects of light water stress on content of chlorophyll,MDA of leaf,soluble sugar and N content of root,stem and leaf were not obvious. |
