Rapid non-destuctive methods for leaf area 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 area estimation in field. The obtained equations were as below: Area (Cm2) = 29.98( Mid leaf width)- 5.987; Area (Cm2) = 31 (leaf base width)– 6.539; Area (Cm2) = 1.472 (leaf length)– 12.25; Area (Cm2) = 0.8062 (mid leaf width * leaf length) +2.474; Area (Cm2) = 1.612 (0.5 mid leaf width* leaf length) +2.747; Area (Cm2) =91.04 – 5.15 (laf length: mid leaf width) + 0.1013 (laflength:mid leaf width)2. The most accurate estimation for irrigated barley was that based on triangle and for droughted that based on rectangle. Rectangle method was preferred for G30, G65, G126, and G154. Mid leaf width method was pfreferred for G54, G83, G94, G98, G119 and G169. Leaf length method was suitable for G77, G116, and G127. Triangle method was best for G74, and G144. Interaction was mentioned in this study.
