Comparative Wood Anatomy of 37 Woody Species of Tamaulipan Thorn Scrub, Northwestern Mexico and Its Relation to Adaptation and Wood Quality: A Synthesis
Journal Title: Journal of Plant Science and Research - Year 2018, Vol 5, Issue 1
Abstract
The paper gives a brief account of wood anatomy of 37 woody species of Tamaulipan Thorn Scrub at Linares, on the basis of transverse, tangential sections and maceration of fiber cells and xylem vessels characteristics. Some of these results are published. In transverse sections there exists large varia variations in distribution of xylem vessels, varying in size, arrangement in radial bands, groups or isolated which are the characteristics of the particular species, inter-specific. Many of the species possess narrow vessels which are reported by authors against occlusion owing to drought or cold, an adaptive trait. Some species poses high density of thick walled lignified fiber cells which I related to the production of strong furnitures, few having soft fibre cells which may be related to paper quality. In transverse sections, the species show variation in the type of axial parenchyma, paratracheal, apotracheal, etc, characteristics of the species. In tangential sections the species show variation in the types of ray parenchyma, uniseriate, long or short or multiseriate, long and short, Fiber cells show variation among species in the length, breadth, cell wall thickness which may be related to taxonomic determination and quality determinations of the species. Vessels show variation in length, breadth, inclination of end walls which may be related to evolutionary trends and taxonomic determination of the species. Therefore, wood anatomy plays an important role in taxonomic delimitation of the species, adaptation to environmental stresses and quality of wood and its utility.
