Effect of Enhanced UV-B Radiation on Stress Physiology of Mentha piperita L.
The stress physiology of Mentha piperita L.under enhanced UV-B radiation(natural light conrol 0、light UV-B radiation stress 0.15 W/m^2 and heavy UV-B radiation stress 0.35 W/m^2) was studied.The result indicated that Mentha piperita L.made adaptation physiological reaction under enhanced UV-B radiation.The content of proline,soluble sugar and three antioxidases increased while the content of soluble protein decresed under 0.15 W/m^2 UV-B radiation.The content of proline and CAT activity rose firstly,then went down later;the content of soluble sugar and SOD activity rose firstly then stabilized;while the content of soluble protein,MDA and POD activity went down firstly then rose.Though the variation of all the indexs was different under enhanced UV-B radiation,all the indexs except the content of soluble protein were increased compareing to themselves under natual light control.
