In order to evaluate the grain yield stability of 21 oat genotypes, 13 experiments carried out during 6 years (from 2009 to 2015) and across 4 environments in the west of Iran. Five of them were carried out by the author of this thesis during 2013-2015 using a completely randomized block design with three replications under three conditions including irrigated, drought stress and rainfed at the...

In order to study the response of rice genotypes to different levels of nitrogen (N), an experiment was conducted to evaluate growth and development of 28 selected rice genotypes (improved and local from north of Iran, and cultivated in Central Iran) under two levels of N including 2.85 mM (N concentration of Yoshida solution) and 1.42 mM (half the N concentration of Yoshida solution) from ammo...

This study was conducted to investigate the frost status in the 11 commercial cultivars, three newly introduced cultivars and two genotypes of olives. After the occurrence of frost at the Tarom region of Zanjan province in February 2019, three trees from each cultivar were selected. Frost symptoms were recorded based on observational indices. Gas exchange traits (stomatal conductance, transpira...

Drought stress is one of the most important abiotic factors which adversely affects growth, metabolism and yield of crops worldwide. The goal of the research was identify drought tolerate canola genotypes using the different drought tolerance indices. The experiment was conducted as split plot based on randomized complete block design with three replications at the experimental farm of agricult...

.Salt stress is one of the major abiotic stresses especially in arid and semi-arid regions. This investigation was conducted to evaluate the effects of the salt stress on Ascorbate Peroxidase (APX) and Superoxide Dismutase (SOD) activities in safflower genotypes based in on a factorial experiment as a Completely Randomized Design (CRD) with three replications. The experimental factors were six ...

Two-spotted spider mite) Tetranychus urticae) is one of the most important pests of common bean (Phaseolus vulgaris) in Iran. Common bean seedlings are susceptible to the mite and greenhouse is a suitable environment for two spotted spider mite reproduction. Accordingly, to evaluate the mite resistance, 19 common bean genotypes were planted in a completely randomized design arrangement with t...

To determine the ideal genotypes in terms of the quantity and quality of fruit, 32 genotypes of greengage were evaluated in a randomized complete block design with three replications at the research station of Horticultural Research Institute in Karaj during two cropping seasons 2018 and 2019. To evaluate the genotypes and to determine the ideal genotype, 26 traits related to fruit, fruiting an...

   In order to evaluate of lentil landrace genotypes response via germination and seedling traits to drought and salinity stress, one factorial experiment with three factors (drought, salinity and genotypes) on bias Completely Randomized Design was conducted with three replications at the laboratory of agricultural faculty of Islamic Azad University of Tabriz branch. The levels of factors were ...
