Study on Leaf Epidermis Structure and Dust-retention Ability of Five Machilus Species
Journal Title: 河南科技大学学报（自然科学版） - Year 2019, Vol 40, Issue 2
Abstract
The seedling leaves of five Machilus species ( Machilus minkweiensis, Machilus parabreviflora, Machilus microcarpa, Machilus pauhoi, and Machilus yunnanensis) were taken as research objects.Morphological characteristics of leaves were observed. The leaf area, content of heavy metal element Pb, Cr, Fe, Cu, Cd, length and width of lower epidermal cell, and length of stomatal apparatus were measured to comprehensively assess and compare the dust-retention abilities of leaves. The results show that there are obvious differences in the leaves external morphology of five species Machilus, and their vein structures are different. The total amount of heavy metal element Pb, Cr, Fe, Cu, Cd in the dust on the unit leaf area from high to low is Machilus parabreviflora > Machilus microcarpa > Machilus pauhoi > Machilus minkweiensis > Machilus yunnanensis. The sizes of the leaf lower epidermal cells are various. Machilus minkweiensis is the largest, while Machilus yunnanensis is the smallest. The length of stomatal apparatus of Machilus pauhoi is the biggest, while Machilus yunnanensis is the smallest.
