Abstract

Abstract: The leaf epidermal micromorphological pattern of six species of Rhododendron plants distributed in the Jiaozishan National Protected Area in Yunnan province were observed by the imprinting method.The leaf epidermal morphological index was measured in the software IT 2.00.The results showed that the stomata were distributed in groups in the six Rhododendron plants;and the significance test analyses exhibited that the average distance between the stomata within the stomatal group was significantly smaller than that between adjacent two stomatal groups.This phenomenon of stomatal groups is firstly found on the leaves of Rhododendron plants,and the physiological effects and formation mechanisms of stomata groups have been discussed.

Key words: stomatal groups, Rhododendron, Jiaozishan, leaf epidermis
