以经秋水仙素处理后加倍的四倍体剌葡萄植株为试材,观察其叶片形态、枝蔓节间长度与粗度、叶片气孔、棚栏组织等的变化.结果表明,与二倍体相比,四倍体植株的叶片变厚,叶形指数变小,叶色变深,叶表面皱缩粗糙,节间变短,植株变矮;叶片气孔密度减小,保卫细胞增大,叶片栅栏组织增厚. The changes of leaf morphology, length and thickness of branches and leaves, leaf stomatal conductance and stem column organization were observed with the quadruplicate Sesame grapes doused by colchicine treatment.The results showed that with the diploid phase Compared with the tetraploid plant, the leaves became thickened, the leaf index became smaller, the leaf color became deeper, the surface of the leaf became thicker and wrinkled, the internodes became shorter and the plant became shorter. The stomatal density decreased, the number of guard cells increased, Tissue thickening.
