Abstract

Woody trees increase in girth by the activity of meristematic tissue called vascular cambium. The vascular cambium comprises fusiform and ray initials, which give rise to vertically oriented elements that is, vessels, fibers, tracheids etc. and horizontally oriented elements that is, rays. The present study reveals that there is reduction in dimensions and proportions of fusiform and ray initials in Juglans regia growing under impact of cement dust pollution.

 

Key words: Vascular cambium, cement dust pollution, Juglans regia.
