-
Abstract
The relationship between the leaf construction and the freezing hardiness of the species Magnoliaceae, Michelia martinii etc is that the number of stomata per area is negative to the freezing hardiness and the thickness of cuticle of the upper epidermis and the thickness of the palisade mesophyll is positive to the freezing hardiness.
