stress management is considered as an important factor in nowadays landscape. therefore this research was conducted using a factorial experiment based on a randomized completely design with regulated deficit irrigation at four levels (100, 75, 50, and 25% of lawn irrigation requirement) and three replicates to evaluate some biochemical and physiological traits on four groundcover plants (lolium...

In this study, seven walnut populations (Rabor, Hanza, Sardoueih, Dalfard, Bidkhan, Dehbakri, and Baft) were selected from Kerman province and compared for drought stress tolerance. Water potential between 0 and -1.5 MPa was obtained by polyethylene glycol 6000 solutions. Germination percentage, leaf relative water content (LRWC), and growth parameter of seedlings diminished with increasing dro...

To evaluate deterioration of oat seeds during storage, we analyzed oxygen radicals, antioxidant enzyme activity, proline content, and gene transcript levels in oat seeds with different moisture contents (MCs; 4, 16, and 28% w/w) during storage for 0, 6, and 12 months (CK, LT-6, and LT-12 treatments, respectively) at 4°C. The germination percentage decreased significantly with higher seed MCs an...

water deficit stress permanent or temporary limits the growth and distribution of natural vegetation and performance of plants more than other environmental factors. in order to investigate the effect of drought stress and mycorrhizal-arbuscular fungi inoculation on the growth and yield of savory (satureja hortensis l.) a factorial experiment based on completely randomized design were conducted...

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 ...

When freshly isolated chick embryo tendon fibroblasts were incubated at 37” with [‘%]proline and 0.5 mM cy, CLdipyridyl, a ferrous iron chelator which inhibits prolyl hydroxylase, the labeled unhydroxylated procollagen molecules accumulated intracellularly. When pepsin digestion at 15” was used as an enzymatic probe of conformation, these molecules were shown to be non-triple helical, indicatin...

soil and water salinity is a major constraint in arid and semi-arid regions. in order to study the impact of water salinity on physiological characteristics and dry matter production of six linseed genotypes, a 4-replicate factorial randomized complete block pot experiment was conducted. salinity consisted of four levels: 0 (control), 35 (low salinity), 70 (intermediate salinity) and 105 mm (se...

In order to survey effect of salinity and cadmium on catalase and peroxidase enzymes activity , proline accumulation, Malondialdehyde and protein content variation in  Brassica oleracea an experiment was conducted in green house condition factorial design based on completely random block in 2014 year. The first factor was cadmium at four levels (0, 50, 100 and 200 ppm) and second factor was sal...

in this study, effect of different concentration of ascorbic acid (asa, 0, 2, 4 and 6 mm) on delaying senescence in cut rose flowers cv. royall class was investigated based on factorial design. the results showed that the greatest delay in senescence was obtained with 4 mm asa as compared to control (distilled water). therefore, fresh weight and diameter of flowers treated with 4 mm asa was mor...
