application of salicylic acid (sa) as a phytohormone has been increased due to resistance to stresses such as drought. the main goal of this experiment was to evaluate the effects of sa on morphological and physiological characteristics of cucumber seedlings under drought stress. for this purpose a factorial trial based on completely randomized design was conducted with 5 levels of sa (0 (contr...
rapid germination is an important factor determining the final yield. the most important abiotic stress threatening lentils is drought and temperature. therefore, this study was performed with the aim of investigating effects various thermal treatments (5, 10, 15, 20, 25 and 30°c) and four levels of drought (0, -4, -8, -12 and -16 bar) on percentage and germination rate of lentil genotypes. a s...
چکیده: پژوهش حاضر به بررسی تطبیقی اعتماد اجتماعی در بین دبیران زن و مرد مقطع راهنمایی شهر ایلام می پردازد. امروزه در جوامع شاهد گسترش ارتباطات هستیم و با توجه به این که دامنه کنش های اجتماعی از حد روابط با آشنایان و دوستان فراتر رفته و به تعامل با کنشگران غربیه و نا آشنا گسترش یافته است، لزوم وجود اعتماد، بیش از پیش احساس می شود. اما با توجه به نقش دبیران در نهادهای آموزشی، در انتقال ارزش ها و...
This research was carried out in a factorial split plot experiment based on a randomized complete block design with four replications in Semnan Agriculture Research Center, Bastam, central Iran, in 2019. Experimental treatments included irrigation as the main factor at three levels of 100, 75 and 50% of water requirement and sub-factors including cultivar at three levels (Titicaca, Q26 and Q29)...
Salt and drought are two major environmental stresses that affect growth and development of plants. In order to study the effects of sodium chloride and polyethylene glycol (6000) on germination characteristics and early seedling growth of redroot pigweed (Amaranthus retroflexus), two completely randomized designs with 4 replications were conducted at Weed Research Laboratory of Bu-Ali Sina Uni...
to evaluate the growth regulatory effect of chlormequat chloride (ccc) under drought stress conditions on three barley cultivars, a field study was conducted under badjgah agro climatic conditions (altitude 1810 m, longitude 52° 46´, and latitude 29° 50´) during 2003-2004 growing season. a randomized complete block based split- split plot of four replications was employed with two moisture leve...
Plant growth is greatly influenced by environmental stresses including water deficit, salinity and extreme temperatures. Therefore, the identification of genes, especially regulatory ones whose expression enables plants to adapt to or to tolerate these abiotic stresses, is very essential. MYB proteins, a superfamily of transcription factors, play regulatory roles in developmental processes and ...
Drought stress is the most important factor restricting both growth and crop yield formation under arid and semi-arid conditions. In a field experiment, the effects of foliar application of growth regulators of auxin at three levels (0, 20 and 40 mg/L) and cytokinin at three levels (0, 50 and 70 µmol) at pollination stage on yield and yield components of a bread wheat (Shiraz cultivar) and duru...
drought, withnegative impacts on plant growth and development, isa major abiotic stress. in order to decreasing drought stress injuries and recognizing red peppers tolerance physiology against drought stress in greenhouse conditions, an experiment with three levels of drought stress (irrigation at 100, 60 and 30% of field capacity) and four concentrations of 5-aminolevolinic acid ((ala; 0, 0.25...
In order to investigate the effect of drought stress and nitrogen application on growth and some physiological characteristics of sorghum genotypes, an experiment was conducted in a split-split plot with randomized complete block design in three replications at Research farm of collage of agriculture, Isfahan University of Technology. Experimental treatments consisted of two irrigation regimes ...
