| Abstract: | Under the low temperature conditions in the field, the effect of MET on the chilling-resistance of rape(Brassica napes L.)was studied from morphology, structure of leaf and leaf stalk and physiological effects in this paper. The experimental results showed that rape seedling treated with MET were creep, the bolting rate and freeze injury index reduced 8000 than that of control before winter. vascular differentiation of leaf stalk was accelerated, layer number of mesophyll was increased, relative permeability of leaf cell membrane reduced and the content of osmosis material such as soluble sugar and proline incrzased. It indicated that MET treatment can improve the chilling-resistance of rape. |
