Large intercellular spaces were found in uniseriate as well as multiseriate cambial rays of Tectona grandis L., Azadirachta indica A. Juss., and Tamarindus indica L. During the period when the cambium is inactive, some of the ray cambial cells became oval to circular, resulting in the development of intercellular spaces. However, the cells were polygonal and compactly arranged during active growth of the cambium. Similarly, such spaces were also noticed in the rays of phloem and xylem. The occurrence of intercellular spaces in cambial rays is correlated with the phenology of trees and local climatic factors, and their possible significance is discussed. |
