Tissue Differentiation in the Embryo of Albizia Distachya Macb

Abstract

Emphasis in most embryological stuaies has been directed towards an investigation of wall patterns, formed during initial divisions of the zygote and the resultant daughter cells. Literature on early embryogeny of many plants has been treated comprehensively by several authors (Johansen, 1950; Maheshwari, 1950; Wardlaw, 1955). In contrast, as emphasized by Esau (1953) in her review of the subject, and Johansen (1950), very few investigations have been made of later embryogeny in the angiosperms with particular reference to the organisation of the systems of primary meristematic tissues (Mahlberg, 1960; Miller and Wetmore, 1945; Nast, 1941; Reeve, 1948).
