Rapid non-destuctive methods for leaf weight estimations of 16 droughted and irrigated barley (Hordeum vulgare) genotypes
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 4
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 weight estimation in field. The obtained equations were as below: Leaf weight (g)= -0.1532+0.5653(base leaf width), Leaf weight (g)= -0.1559+0.5717(mid leaf width), Leaf weight (g)=0.00509+0.01539 (leaf L*W), Leaf weight (g)=0.00509+0.03077 (leaf L*0.5W), Leaf weight (g) = -0.2647+0.02768(leaf L), Leaf weight (g)= 0.6431-0.006207(L/W). Mid W method was the most accurate method for estimating leaf weight of irrigated and droughted barley. L, method was preferred for G77, G83, and G94. Mid W, method was the most accurate for G54, G98, G126, and G154. Triangle was the accurate for G30, G74, G119, G127, and G144. Rectangle was the most suitable for G65, G116, G142, and G169. Each individual investigated irrigated and droughted genotype was mentioned its suitable estimation method.
