Abstract

 In order to study the effect of plant DENSITY on MORPHOLOGICAL AND PHYSIOLOGICAL CHARACTERISTICS in four CULTIVARs of DURUM WHEAT (Triticum turgidum var. durum) under dryland, a field experiment was conducted in Sarableh Agriculture Research Station of Ilam province during 1998-99 year. The experiment was factorial design based on RCB (Randomized complete) with four replications. The factors were CULTIVARs (Chalavandi Saymareh, Aconchi and Chenalter) and plant densities (300, 350, 400 and 450 plants/m2). Therefore, the effect of plant DENSITY and CULTIVARs on morphplogical and physiological characteristics such as, stem length, spike length, peduncle length, peduncle diameter, leaf area index, flag leaf area, dry matter cumulative, tiller process, YIELD and YIELD components, biological YIELD and harvest index, were evaluated. The results showed that CULTIVAR and plant DENSITY effects were not significant for grain YIELD, biological YIELD and harvest index. There was a significant difference between CULTIVARs related to YIELD components, stem length and peduncle length. The results showed that the plant DENSITY effects were significant for YIELD components, spike length and peduncle diameter, but the Interaction effects only for 1000-grain weight were significant. Chalavandi CULTIVAR at 300 plants/m2 with 38.2gr and Aconchi at 450 plants/m2 with 27.7 gr were given the highest and lowest 1000 grain weight respectively. Regarding comparison of the means using Duncan's approach, the highest Grain YIELD for Chenaltar CULTIVAR with 1317 kg/ha and lowest the DENSITY of 350 plants/m2 with 1347 kg/ha were obtained.
