Drought stress is a critical and inevitable phenomenon damages successful crop production in various intensity every year in different parts of the world during different times. This research was done to evaluate the effects of drought stress on some traits related to leaf (leaf weight, leaf area and chlorophyll content) root (root weight) and shoot (weight and length) further enzymatic antioxi...
In order to evaluation of influence of sulphur fertilizer on grain yield and the some of physiological indices of canola, an split plot experiment based on randomized complete block design was conducted in Research Farm Islamic Azad University, Ardabil branch in 2007. Factors were: sulfur fertilizer at four levels (0 as control, 25, 50 and 75 kg S/ha) in the main plots and canola cultivars at t...
this study was carried out in order to determine the leave characteristics of some chestnut genotypes in the central black sea region of turkey and also to determine whether the leaf morphometric characteristics could be used for differentiation of genotypes. in this study, seven chestnut (castanea sativa mill.) genotypes (sa5-1, se 3-12, se 21-2, se 21-9, 552-8, 556-7 and 556-8) and one cultiv...
Rose flower (Rosa hybrida) is appreciated for its beauty, fragrance and long period of flowering. To study the response of cut rose flower to bio-fertilizers, a factorial experiment was performed, with completely randomized design and four replications, in hydroponic greenhouse of Alandasht, Astane Ghods Garden, Mashhad, Iran, during 2009-2010. The first factor was six cultivars of rose flower ...
Identify the indices of leaf growth and development and study of phyllochron in commercial cultivars of sugarcane with the aim of better management of agricultural practices is very important. A field experiment was conducted in Amir Kabir Agroindustry in the south of Khuzestan, Iran in 2015-16 in randomized complete block design with three replications. The sugarcane cultivars included; CP69-1...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
A field experiment was carried out during the 2013-2014 growing season in Lorestan Province (Iran) to evaluate the effect of three planting densities (30, 55, and 83 plant.m-2) on growth indices and grain yield of four chickpea cultivars (Azad, Hashem, Arman and ILC482) under the fall dry land farming condition. The experiment design was factorial based on a randomized complete block design (RC...
The aim of this research was to investigate the root colonization percentage of grain sorghum cultivars by two species of mycorrhizal fungi and its effect on some of morphological and agronomic traits. Experiment was laid out as factorial based on randomized complete block design with three replications. Experimental treatments included three levels of fungi (F1: control without inoculation, F2...
In order to study the effect of drought stress on some growth indices of oil sunflower cultivars, a study was conducted in Isfahan. The experiment was conducted as split plots in a randomized complete blocks design with three replications in Isfahan (51° 48' E, 32° 40' N).Main plots were drought stress in four levels (80, 100, 120, and 140 mm evaporation from evaporation pan class A and cultiv...
this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
