EVALUATING DROUGHT RESISTANT WHEAT CULTIVARS BASED ON STEM ANATOMICAL CHARACTERISTICS
Journal Title: Journal of Experimental Biology and Agricultural Sciences - Year 2017, Vol 5, Issue 0
Abstract
Water stressed have vital effect on the various anatomical, physiological and bio-chemical processes, whichare controlled by genetic and prevailing environment. In present study, 25 wheat (Triticum aestivum L.)cultivars, which have been released over 40 years in Iran, were evaluated in terms of stem physiological andanatomical changes at Iran Agricultural Research Station. During growing season data were collected andfinally crop was harvested in June and various anatomical aspects like Thickness of stem (TS), Thickness offiber (TF), Tangential dimension of collenchymas cells (TDC), Tangential dimension of vascular bundle(TDVB), Radial dimension of vascular bundle (RDVB), Radial dimension of big xylem vessel (RDBXV),Tangential dimension of phloem bundle (TDPB), Distance between vascular bundle to Epidermis (DBVBE),Thickness of epidermal cell (TE) that are integral part of drought resistance were studied. Predominantlydrought resistant genotypes were recorded with anatomical aspects which play major role in imparting droughtresistance. Among the studied 25 genotypes, genotype number 7, 21 and 25 showed maximum droughtresistance characteristics collectively and these can be used as parent cultivars for future breeding programs.
