Salicylic acid (SA) is a phenolic compound and its foliar application shows regulatory effects on plants. In this research, Ajowan (Carum copticum) plants were treated with 0, 0.5, and 1 mM SA and proline, total phenol, chlorophylls, carotenoids, soluble sugar, N, P, and K contents were studied. Results showed that application of SA affected both quantitative and qualitative traits of ...

in order to study the effects of pgpr application methods on proline and soluble sugars content of yarrow (achillea millefolium l.) under drought stress conditionsan experiment was performed at islamic azad university, yadegar-e-imam khomeini (rah) shahre-rey branch. this experiment was carried out in a split plot arrangement with randomized complete block design in three replications. experime...

abstract in order to study the effect of different water potential on anethum graveolens two experiments were conducted for germination and vegetative stages. this study was carried out as a factorial experiment based on completely randomized design with three replications. in the first experiment, response of dill seeds germination to levels of drought stress including to drought potentials ze...

studying the physiological responses of linseed genotypes to water deficit stress may be helpful in recognizing the linseed resistance mechanisms to the latter stress factors. therefore, a split plot rcbd field experiment was conducted with three replications to explain interrelations of leaf chlorophyll, proline and soluble carbohydrates content and grain yield of six linseed genotypes under t...

this study was conducted to determine the combined effects of salicylic acid (sa) and arbuscular mycorrhizal fungi (amf) (glomus mosseae) symbiosis on the growth of pistachio seedlings (pistacia vera ‘abareqi’) grown in the greenhouse under different drought stress (ds) levels. the arbuscular mycorrhizal fungi (amf) colonization or exogenous sa treatment could increase ‘abareqi’ pistachio seedl...

Osmotic adjustment was studied in cultured cells of tomato (Lycopersicon esculentum Mill cv VFNT-Cherry) adapted to different levels of external water potential ranging from -4 bar to -28 bar. The intracellular concentrations of reducing sugars, total free amino acids, proline, malate, citrate, quaternary ammonium compounds, K(+), NO(3) (-), Na(+), and Cl(-) increased with decreasing external w...

environmental stresses such as drought have important effects on plant growth and development. in order to evaluate the effect of drought tolerance, 12 chickpea genotypes were treated with drought stress in hydroponic condition in greenhouses. treatments were a control and two stress treatments -3 and -6 bar that was created with polyethylene glycol in hydroponic condition. two weeks after the ...

The effects of grafting on the morphology, physiology, and aerenchyma balsam pear aboveground under waterlogging stress were studied using a two-factor randomized block design. At 8 16 days, degree reduction grafted was lower than those self-rooted pear, although height leaf number pears remarkably reduced stress. Compared with considerably decreased malondialdehyde content leaves but substanti...

freezing injury is an important limiting factor in the production of pomegranate in iran.the aim of the present study was to evaluate the effect of paclobutrazol (pbz) on cold hardiness of pomegranate (punica granatum l.) cv. ‘malas saveh’. different concentrations of pbz including 0 (control), 31, 62, 125 or 250 mg l–1 were sprayed on one-year-old plants in august and the electrolyte leakage o...
