Lemma micro-morphological characteristics of MT-1 elephantgrass and its closely related varieties

Abstract

Abstract: Micro-morphological characteristics of lemmas of Pennisetum purpureum cv. MT-1 and its closely related varieties were investigated using scanning electron microscopy. An abundant polymorphism of micro-morphological characteristics of lemma was revealed among the elephantgrass varieties. The results showed that there were seven different kinds of epidermal cell, three of which, cross-shaped, dumb-bell-shaped, moniliform cell, were widespread. Eleven different types of indumentums were mainly seen in the middle of the elephantgrass lemma and two of them, microhairs with short basal cell and prickle-hairs were in common. Five elephantgrass varieties were divided into four groups according to different kinds of tubercles. Based on the differences of micro-morphological characteristics of lemma surfaces, MT-1 elephantgrass and its closely related varieties can be identified and distinguished.
