Here are the results: cold mid-type w heat - is similar to cold type w heat and w arm mid type w heat is similar to w arm type w heat in the thickness of functional leaves, the interval of veins and the rate of transverse area of vascular bundle and leaf transverse area. Cold mid-type wheat compared w ith w arm mid-type w heat, there are smaller the , thickness of leaves and the interval of veins and higher rate of transverse area of vascular bundle and - . leaf transverse area in cold mid type w heat leaves Key words: Canopy temperature; M iddle type w heat; Leaf; M icro-structure , , , , , , ; , [ 14] ( ) , [ 9] 3 ( , ) , , ; ; ,
