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...
Among the chemicals that their effects on reducing chilling injury has recently been studied are salicylates and jasmonates. Therefore, in this study the effects of salicylic acid and methyl jasmonate on increasing the cold tolerance of bell pepper cv. Emily was examined. Experiment was done as a 7×2 factorial in the completely randomized design (CRD) with four replications. The first factor co...
abstract the purpose of this research was to transform two economically important cultivars of strawberry with p5cs gene, which encodes δ1-pyrroline-5-carboxylate synthetase (p5cs), the key enzyme in proline biosynthesis. shoots were obtained on ms basal medium supplemented with 2% glucose and 4 mg/l tdz for camarosa and kurdistan cultivars. for genetic transformation, a binary vector pbi121 co...
in this study, the effect of drought stress on morphological and physiological characteristics of wheatgrass and tall fescue was investigated in a factorial-split plot in time arrangement based on a completely randomized design with three replications. after turf establishment, half pots were exposed to drought stress and the half other were completely irrigated. based on the results tall fescu...
perenial rygrass (lolium perenne cv. “numan”)belongs to poaceae family as an important lawn in landscape design. the objective of this research was to evaluate effects of different concentrations of salicylic acid to enhance the growth and biochemical characteristics of lolium perenne l. under drought conditions. factorial experimental design was arranged in a completely randomized block design...
Water and soil salinity on environmental agents limit plant growth and its productivity in Iran. In order to reduce the adverse effects of salinity on plants, different compounds are used. In this study, the effects of salicylic acid and potassium silicate were investigated on wheat plants under salt stress. A factorial experiment in a randomized complete block was conducted by applying 100 mM ...
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...
introduction salinity has various effects on plant growth by affecting physiological processes. the decline in plant productivity under saline condition, frequently linked with the reduction of photosynthetic capability. it has been reported that efficiency of psii photochemistry (fv/fm) of numerous plant species have been decreased due to salt stress studies have shown that salicylic acid (sa...
Black cumin (Nigella sativa) is an annual flowering plant in the family Ranunculaceae that beside medicinal value was used as food and cosmetics products. Salicylic acid is a growth regulator with phenolic nature has main role in regulation of many physiological processes and resistance to environmental stress. In order to study effect of salt stress and salicylic acid on some growth parameters...
two field experiments were conducted at the research farm of the faculty of agriculture, university of tabriz, iran during 2009-2010 and 2010-2011, to evaluate the response of fennel (foeniculum vulgare l.) landraces to limited irrigation. experiments were arranged as split plot based on randomized complete block design in three replications with irrigation treatments (irrigation after 60, 90, ...
