Rapid non-destuctive methods for leaf thickness estimations of 16 droughted and irrigated barley (Hordeum vulgare) genotypes
Journal Title: International Journal of Farming and Allied Sciences - Year 2015, Vol 4, Issue 5
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 thickness estimation in field. The obtained equations were as below: Leaf thickness (mm) = 0.1039+0.5917 (base leaf width, Leaf thickness (mm) = 0.2186+0.0622 (mid leaf width), Leaf thickness (mm)=0.2502+0.002451 (leaf L*W), Leaf thickness (mm) =0.2502+0.002451(leaf L*0.5W), Leaf thickness (mm) = 0.0466+0.01668 (leaf L)- 0.000275 (leaf L)2, Leaf thickness (mm) = 0.3558-0.0027 (L/W). L: W was the most accurate method for estimating leaf thickness of irrigated and droughted barley. Mid W, method was preferred for G54, G119, and G144. L: W method was the most accurate for G74, G116, G126, G127, and 142. Rectangle was the accurate for G65 and triangle for G77. L method was the best G30, G83, G94, G98, G154, and G169. Each individual investigated irrigated and droughted genotype was mentioned its suitable estimation method.
