to estimate plant resistance to cadmium chloride (cdcl2) stress for phytoremediation purposes, the effect of cadmium (cd) phytotoxicity was assessed on total soluble protein, chlorophyll (chl) content and antioxidant enzymes in the leaves of three different brassica napus (b. napus) cultivars; mohican, reg.cob and okapi. plants were exposed to three levels of cdcl2 (0.75, 1.5 and 2.25 mm) in ir...

abiotic stresses including salinity are the major limiting factors of growth and crop production worldwide. microbial endophytes as the most important soil microorganisms, by modifying plants at genetical, physiological and ecological levels increase their yield per area unit and provide the possibility of crop production in saline and arid soils or climates with biotic and abiotic stresses. th...

Nitric oxide (NO) is involved in numerous physiological and stress responses in higher plants. Tomato is one of the most important vegetable crops in the world and previously it has been reported that salinity induced an oxidative stress affecting its redox and NO homeostasis. Using tomato plant exposed to 120 mM NaCl, it was studied whether the exogenous application of NO could ameliorate the ...

in order to study the effect of salt stress at different growth stages on physiological characteristics and enzyme superoxide dismutas (sod) activity in wheat genotypes a green house experiment was conducted at the agricultural research greenhouse, agricultural, medical and industrial research school, nuclear science and technology research institute of karaj. a split factorial design on the ba...

basil (ocimum basilicum l.) belongs to the lamiaceae family as a medicinal plant used in traditional medicine in iran. the purpose of this test is to evaluate the effect of nano fe-chelate under salinity levels on the plant physiology and morphology characteristics. in this experiment  investigated the effect of nano fe-chelate and salinity stress on growth parameters, photosynthetic leaves rat...

This study investigated thiram fungicide-induced-stress effects in tomato plants and the possible protective role of 24-epibrassinolide (24-EBL) response to (tetramethyl thiuram disulfide) toxicity. Tomato seedlings pretreated with 0, 10-11, 10-9 10-7 M 24-EBL were treated 6.6 mM thiram. leaves harvested 5 11 days after treatment (DAT) used for analysis. Thiram application caused oxidative stre...

Methyl jasmonate (MJ) is an important plant growth regulator, involved in plant defense against abiotic stresses, however, its possible function in response to metal stress is poorly understood. In the present study, the effect of MJ on physiological and biochemical changes of the plants exposed to arsenic (As) stress were investigated in two Brassica napus L. cultivars (ZS 758 - a black seed t...
