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...

wild jujube, ziziphus lotus, is a multipurpose xerophytic shrub of the rhamnaceae family widely distributed in arid and semi-arid regions of tunisia, where it occupies most soil types. the fruit is the edible part of the plant by local population. the reintroduction of this shrub requires the control of its multiplication in response to water shortage. this study aims to evaluate growth and wat...

introduction drought stress is the most important growth limiting factor for crop production. sugar accumulation under drought stress strengthens and stabilizes cell membranes and maintains the water absorption and turgid property. under stress conditions, proline will also maintain the turgor pressure and decreased the damages caused to plant membrane. although proline concentrations may have ...

in order to investigate the effect of cycocel on different growth aspects of two olive cultivars (mary and mission), a greenhouse experiment was conducted taking into account three factors of: cycocel at three levels (0, 500 and 1000 mg l-1), drought stress of three levels (irrigated at 5, 10 and 15 days intervals) and two olive cultivars (mary and mission) in a factorial experiment based on ra...

Silicon (Si) has been known to augment plant defense against biotic and abiotic pressures. Maize (Zea maize L.) is classified as a Si accumulator and is relatively susceptible to alkaline stress. In this study, seeds of maize were grown in pots and exposed to various concentrations of Na2CO3 (0, 25, 50, and 75 mM) with or without 1.5 mM Si in the form of sodium metasilicate Na2O3Si.5H2O for 25 ...

introduction dehydration is one of the limiting factors of crop production. it results from increasing the amount of water losses from leaf or inadequate water absorption rate or combination of both. zinc used in many enzymes of the plant tissues and have catalytic role in activation of some enzymes. zinc is involved in the synthesis and degradation of proteins and is an essential micronutrien...

among the environmental stresses, salinity is a major limiting factor in world legumes production is considered. in this study, sodium chloride and salicylic acid interaction on growth parameters were investigated in greenhouse with factorial arrangement in randomized complete block design with three replications. the plant consisted of three cultivars of lentil (kimiya, kermanshah and gachsara...

theeffect of salt stress on the pysiological and biochemical responses of the seedlings of eight eucalyptus species viz. e. kingsmillii, e. tetragona, e. salubris, e. occidentali, e. microtheca, e. camaldulensis, e. globules and e. sargentii was analyzed. four month-old seedlings grown in greenhouse were watered by five levels of salt solution (0, 50, 100, 150 and 200 mm of nacl) in five replic...
