the use of natural compounds to control plant pathogens lead to reduction in using fungicides. chitosan with duble effects, control pathogenic microorganisms and activate inducing defence responses, has been shown to be a reliable nontoxic material in the plant-pathogen interaction. the aim of this research was to consider the effects of chitosan and calcium chloride on decay and quality attrib...

tolerance of two apple rootstocks (gami and m26) was evaluated at different concentrations of sodium chloride in vitro conditions. micro plants grown under ms medium culture were transferred to knoudson–c culture medium devoid of na and cl ions. concentrations of nacl in the knoudson-c culture medium were 0, 20, 40, 60, 80 and 100 mm/l. six weeks after culturing, data were collected. the result...

Salinity stress is one of the main limiting factors for optimum agricultural productivity of safflower, Carthamus tinctorius L., in arid and semi-arid regions. It could leads to significant changes in plant biochemical, physiological, and growth traits. Salinity induced endogenous rise in jasmonic acid and its methyl esters (MeJA) has been reported. In the present study, effects of salinity str...

The cultivation of tolerant species with low-quality irrigation water is one the main strategies to address lack availability water. In this work, effect salinity on plant growth, nutritional composition, and quality features Hedypnois cretica Urospermum picroides was tested. Fresh yield leaves roots both were severely decreased under high salinity, while mineral profile also showed a decrease ...

In current studies, the physicochemical properties of water, such as total dissolved solids, salinity, and electrical conductivity, are used mainly to investigate changes in surface water groundwater. our experimental study, we aimed introduce bodies into field paleoenvironmental changes. We employed property indexes sediment lixiviums two research sections sea–land interaction zone eastern mar...

The effect of soluble solids on the Zetapotential (ξ) of a cloudy apple juice was investigated. Apple juice was enzymatically treated with pectinolytic enzymes and diafiltred with a polysulphone UF membrane (100 kDa) to eliminate soluble solids. Most soluble solids were removed after 4 equivalent sample volumes (ESV) of washing water. During a second period, from 5 to 23 ESV, diafiltration rate...

Accumulation of soluble salts in arid areas which are similar to most regions of Iran is inevitable in soil surface and profile because of low precipitation and high evaporation. High concentration of soluble salts in soil profile caused severe problems for root water uptake thus plant growth stopped. Reducing soil salinity to optimized content by leaching and avoiding soil pounding must be con...

introduction: salinity is the most significant abiotic factor limiting crop productivity and several physiological responses, including modification of ion balance, water status, mineral nutrition, stomatal behavior, photosynthetic efficiency and so on. the gf677 (prunuspersica×prunusamygdalus) is widelyusedas rootstock for peach and almond. it is mainly used as a rootstock because of its resis...

With a mean precipitation rate, much lower than that of the world, Iran is among the countries that face severe water challenges. The present study has dealt with the evaluation of hydrochemistry of Faryab spring water in Hormozgan Province, Iran. Four different composite water samples have been analyzed to detect major anions, cations, total dissolved solids, electrical conductivity, pH, and s...
