Seasonal Pattern of Cell Division in the Vascular Cambium of Some Tropical Timber Trees

Abstract

Seasonal pattern of cell division in a year in four deciduous (Albizzia lebbeck, Dalbergia sissoo, Tectona grandis and Terminalia crenulata) and three evergreen (Calophyllum inophyllum, Mangifera indica and Morinda tinctoria) plants is described in detail. The anticlinal division of fusiform initials were predominantly pseudotransverse although a few radial divisions in Dalbergia and lateral (or tangential) divisions in Albizzia were noticed. There was often a difference in the orientation of the anticlinal division spindles even in the adjacent fusiform initials in the different plants. The timing of both the periclinal and anticlinal and initial location of division were studied and recorded for all plants studied. © 1994, Japan Mendel Society, International Society of Cytology.
