An ontogenetic study with special reference to leaf development in C₃ and C₄ forms of alloteropsis semialata

Abstract

This ontogenetic study conducted at light and electron microscope level, describes several aspects of leaf development in C₃ and C₄ forms of Alloteropsis semialata. Emphasis is placed on the distribution and anatomy of vascular bundles as seen in transverse sections. The derivation of the specialized photosynthetic tissue of the Kranz sheath, which characterizes the C₄ form, is traced in the inner or mestome layer of the double bundle sheath.
