At percent, Zn stress tolerance using novel genetic resources is an important mitigation strategy for plant breeding. In this study, thirty-five durum wheat genotypes with different growth habits were evaluated under normal (non-stress) and Zn deficient stress during the 2014-15 cropping season. A total of ten Zn stress tolerance indices including stress tolerance index (STI), relative zinc-def...

با توجه به اینکه کمبود آب یکی از مهم ترین عوامل محدود کننده تولید محصولات زراعی در مناطق خشک و نیمه خشک می باشد لزوم شناسایی ارقام مقاوم به خشکی و همچنین معیارهای مناسب برای انتخاب این گونه ارقام ضروری است. لذا به منظور بررسی عملکرد، اجزاء عملکرد ژنوتیپ های مختلف ارزن و تعیین متحمل ترین ژنوتیپ براساس شاخص های تحمل به خشکی تحت رژیم های مختلف آبیاری آزمایشی به صورت کرت های خرد شده در قالب طرح بلو...

In order to investigate yield, yield components and quality traits of P. ovata and P. psyllium under water stress and plant density, two experiments were conducted at the Agriculture Research Field, University of Tehran, Karaj, in April 2005 and 2006. Two Factorial experiments based on randomized complete block design with three replications were used. The treatments were three levels of water ...

To investigate the effect of drought stress and plant density on yield and yield components of maize KSc 301 hybrid, a two-year study (2007-2008) was carried out in Varamin Agricultural Research Center by using strip split plot randomized based on complete block design in three replications. Four water stress levels (before flowering, during flowering and grain filling stage and no stress) were...

The different regimes of flow when separating two solid rough surfaces in contact via a layer of a simple yield stress fluid are identified. Generic scalings for the adhesion energy and for the geometrical characteristics of the final deposits (after separation) as a function of the initial aspect ratio of the sample are found. We show that there is a strong pinning effect which might be at the...

In order to study of agronomic, physiological characteristics, drought tolerance and to identify  Agro-physiological traits associated with drought tolerance, 19 durum wheat genotypes consisting of 17 advanced breeding lines and two control cultivars (Saji and Zahab) were evaluated in a randomized complete blocks design with three replicated under both stress (rainfed condition) and non-stress ...
