| Abstract: | By using 1.0mg.L-1 sodium selenite to deal with the pear leaves before hand,after 4d stress them with High temperature.The in dividual figures were them taken after 5h.The result shows that using so- dium selenite in the density of 1.0mg.L-1 to treat the diseased pear leave can raise the activity of GPX,GX and POD,and reduce the activity of LOX. |
