Bu araştırma, bazı arpa çeşitlerinde başaklanma döneminde ölçülen fizyolojik özellikleri ile verim ve verim unsurları arasındaki ilişkileri değerlendirmek amacıyla yapılmıştır. Arazi çalışması, Şırnak ekolojik koşullarında 2015-2016 yetiştirme döneminde tesadüf blokları deneme desenine göre dört tekrarlamalı olarak yürütülmüştür. Materyal olarak iki sıralı Barış, Pandora ve altı sıralı arpa çeşitleri kullanılmıştır. Çalışmada, yaprak alanı indeksi YAI , SPAD, normalize edilmiş vejetasyon indeksi NDVI , bitki örtüsü sıcaklığı BÖS , protein içeriği, hektolitre ağırlığı, bin dane ağırlığı, nişasta içeriği ve tane verimi özellikleri değerlendirilmiştir. Araştırma bulgularına göre genotipler arasındaki farklar protein içeriği, nişasta içeriği, verim, bin tane ağırlığı ve hektolitre ağırlığı açısından önemli bulunmuştur. Arpa çeşitlerinde incelenen özelliklere göre SPAD değeri 30.85-35.43, YAI değeri 1.70-2.30, NDVI değeri 0.505-0.533, BÖS değeri 15.45 °C -17.85 °C, tane verimini 1958-3093 kg ha-1, bin dane ağırlığı 32.55-46.27 g, hektolitre ağırlığı 66.35-73.40 kg hL1, protein içeriği% 8.1-9.1, nişasta içeriği % 63.13-66.49 arasında bulunmuştur. Tane verimi ile bitki örtüsü sıcaklığı arasında önemli r = 0.989 ** ilişki bulunmuştur

Evaluation of Relationships Between Yield and Yield Components with Physiological Parameters in Barley Hordeumvulgare L. Genotypes

This research was carried out to assess the relationships between yield and yield components with physiological traits which measured at the heading stage of some barley cultivars. The field experiment was arranged as the complete block design with four replications during the 2015-2016 growing seasons under Sirnak ecological conditions. Six-rowed and two-rowed Baris, Pandora barley cultivars were used as a material. Leaf area index LAI , SPAD, Normalized Differences Vegetative Index NDVI , Canopy Temperature CT , Protein Content, text weight, thousand kernel weight, starch content and grain yield were evaluated. According to the findings of research, differences between genotypes were found significant for protein content, starch content, yield, thousand kernel weight and test weight. The investigated traits ranged between 30.85-35.43 in SPAD, 1.70-2.30 in LAI, 0.505-0.533 in NDVI, 15.45°C-17.85 °C in CT, 1958-3093 kg ha-1 in grain yield, 32.55-46.27 g in thousand kernel weight, 66.35-73.40 kg hL-1 test weight, 8.1-9.1% in protein content, 63.13-66.49% in starch. Grain yield showed significant r=0.989** relationships with canopy temperature
