TAILIEUCHUNG - Spectral reflectance indices as a rapid and nondestructive phenotyping tool for estimating different morphophysiological traits of contrasting spring wheat germplasms under arid conditions

The aim of this study was to investigate whether spectral reflectance indices could be used to estimate different destructive morphophysiological traits of a wide and diverse range of spring wheat germplasm in a rapid and nondestructive manner. | Turkish Journal of Agriculture and Forestry Research Article Turk J Agric For (2015) 39: 572-587 © TÜBİTAK doi: Spectral reflectance indices as a rapid and nondestructive phenotyping tool for estimating different morphophysiological traits of contrasting spring wheat germplasms under arid conditions 1,2, 1 1,3 Salah EL-HENDAWY *, Nasser AL-SUHAIBANI , Abd El-Azeem SALEM , 4 5 Shafiq UR REHMAN , Urs SCHMIDHALTER 1 Department of Plant Production, College of Food and Agriculture Sciences, King Saud University, Riyadh, Saudi Arabia 2 Department of Agronomy, Faculty of Agriculture, Suez Canal University, Ismailia, Egypt 3 Department of Field Crops Research, National Research Center, Giza, Egypt 4 Department of Botany, Kohat University of Science & Technology, Kohat, Pakistan 5 Department of Plant Sciences, Technische Universität München, Freising-Weihenstephan, Germany Received: Accepted: Published Online: Printed: Abstract: The aim of this study was to investigate whether spectral reflectance indices could be used to estimate different destructive morphophysiological traits of a wide and diverse range of spring wheat germplasm in a rapid and nondestructive manner. A total of 90 spring wheat germoplasms were evaluated under water shortage by applying only three irrigations during the growing cycle of germplasm with the amount of water totaling 2550 m3 ha–1. Ten selected spectral reflectance indices were related to the green leaf number per plant, green leaf area per plant, total dry weight per plant (TDW), grain yield per hectare (GY), leaf water content (LWC), leaf area index (LAI), and canopy temperature (CT). Significant genotypic variability was shown for all morphophysiological traits and the ten selected spectral reflectance indices. The broad-sense heritability of the normalized water index (NWI)-3, NWI-4, water band index (WBI), and normalized .
