There was no significant difference in LL/LW, P/S, epidermal thickness and stomatal density along the elevation gradient.

叶长宽比、P/S的比值、表皮厚度与气孔器密度无明显差异。

Results:The thickness of epidermis layer was reduced obviously in diabetic skin, with morphological characteristics of obscuring of multiplicity of epidermal cell layers.

结果：糖尿病皮肤表皮细胞层次欠清晰，部分表皮缺乏复层排列，棘细胞数量明显减少，表皮层厚度明显变薄；

Both pubescence density and soluble sugar were negatively related to non-preference, while the free amino acids and thickness of epidermal cell positively.

叶毛密度和可溶性糖含量与不选择性呈负相关，游离氨基酸和表皮层细胞厚度与不选择性呈正相关。
