Rapid non-destuctive methods for leaf size estimations of 16 droughted and irrigated barley (Hordeum vulgare) genotypes
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 3
Abstract
16 Barley (Hordeum vulgare) genotypes, namely G30, G54, G65, G74, G77, G83, G94, G98, G116, G119, G126, G127, G142, G144, G154 and G169, were subjected to adequate irrigation during their growing season and to drought only during spike development stage, to create new equations through regression for rapid leaf size estimation in field. The obtained equations were as below: Leaf size (cm3)= -0.3271+1.003(base leaf width), Leaf size (cm3) = 0.3212+0.9987(mid leaf width), Leaf size (cm3)=0.2502+0.002451(leaf L*W), Leaf size (cm3) =0.2502+0.002451(leaf L*0.5W), Leaf size (cm3) = 0.41+0.04464 (leaf L), Leaf size (cm3) = 2.647-0.14171(L/W)+0.002628 (L/W)2. L method was the most accurate method for estimating leaf thickness of irrigated and droughted barley. L, method was preferred for G30, G54, G77, G127 and G142. Mid W, method was the most accurate for G65, G74, G98, G116, G126, G144, G154, and G169. Triangle was the accurate for G83, G94, and G119. Each individual investigated irrigated and droughted genotype was mentioned its suitable estimation method.
