The experiment was conducted in 2012 to evaluate the effect of salinity stress on oil percent, oil yield, seed yield and some physiological charactristics on three local populations of castor bean (Ricinus communis L.), at the University of Shahrekord, Iran. Experiment was carried out with three replications in a completely randomized design including five levels of salinity (1.2, 2, 2.6, 3.8 ...
Cantaloupe is one of the most important of vine crops in Iran that today its yield has been decreased due to reduction in the quantity and quality of water resources and also due to increased soil pH because of bicarbonate ion aggregation in the soil. In order to maintain the production quality of this plant, appropriate crop management techniques are needed. For this purpose, to investigate th...
Salinity of soil is a major abiotic stress limiting the crop production and growth of peppermint. The aim of study was assessment the plant growth regulators efficacy (salicylic acid (SA), jasmonic acid (JA), brassinosteroids (BRs), and non-application of hormone as control) on physiological traits of peppermint under salinity stress (0, 30, and 60 mM). The experiment was conducted using the co...
Salinity is a serious problem for expansion of agriculture, especially in arid and semi-arid regions. On the other hand, various benefits of soilless culture have caused the expansion of this system in these areas. In order to investigate the effect of different levels of salicylic acid and salinity stress on vegetative and physiological characteristics of eggplant, a factorial experiment was c...
Abstract: In this study, a greenhouse study was conducted to investigate the growth of Aloe vera with different content of nitrogen fertilizers. Treatments consisted of 0, 0.15, 0.29, 0.43, 0.57 and 0.71 g/pot ammonium nitrate and 0, 0.11, 0.22, 0.33, 0.43, 0.53 g/pot urea. Then the effects of nitrogen fertilizers on fresh weight, photosynthetic pigments and proline content were studied. The...
The paperaim of the was to study the effect of low temperature stress on Avena nuda L. seedlings. Cold stress leads to many changes of physiological indices, such as membrane permeability, free proline content, malondialdehyde (MDA) content, and chlorophyll content. Cold stress also leads to changes of some protected enzymes such as peroxidase (POD), superoxide dismutase (SOD), and catalase (CA...
Salinity is a major environmental factor limiting plant growth and crop productivity. Therefore many studies had been done to minimize the stress effects caused by salinity in agriculture and plant physiology. To access the effect of methyl jasmonate and salinity on peppermint, experiment was conducted as factorial based on a randomized complete design (CRD) with three replications. In this res...
In this research, effect of vermicompost and plant growth promoting rhizobacteria (PGPR) on physiological traits of lemon balm under drought stress condition was investigated in year 2012 at Karaj Research Institute of Forest and Rangelands. Experiment was conducted as split-split plot in a randomized complete block design with three replications. irrigation (normal: irrigated to field capacity...
to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...
in order to investigate the effect of hexaconazole (hex) on the increasing tolerance to water deficit stress of two soybean (glycine max l.) cultivars, an experiment was conducted in faculty of agronomy of tarbiat modares university as factorial experiment in randomized complete block design arrangement. factors examined in this study were included soybean cultivars (l17 and clark63), hex conce...
