The influence of silicon (Si, 3 mM), sodium chloride (NaCl, 135 mM), and Si, 3 mM + NaCl, 135 mM supply on chlorophyll content, photosynthetic activity (CO2 -fixation), the concentration of malondialdehyde (MDA) and H2O2, activities of superoxide dismutase (SOD), catalase (CAT) enzymes, free proline and protein contents were studied in maize seedlings leaves after two month of treatments. The r...

some of the morpho-physiological characteristics related to the leaf growth and development of phaseolus vulgaris l. genotypes have been studied in the field conditions at the seed and plant improvement institute (spii). the study was performed as split plot experiment in a randomized complete block design with four replications in well-watered and water deficit conditions with eight genotypes ...

The issue of high concentration salt in soil is not restricted to coastal areas, but also expands cultivated lands, complicating, or even intercepting, the growth plants. objective this paper study effect zeolite, compost and effective microorganisms (EM), seaweed extract, ceramic powder on MM106 apple (Malus domestica Borkh.) plants normal saline conditions. More specifically, weight dry matte...

The effect of two different copper conditions (deficiency and excess) on the amino acid composition in B. carinata xylem sap was analysed. When the Cu in the nutrient solution was increased from 0.12 to 2.5 or 5 microM, the concentrations of histidine, threonine, glutamine, proline, methionine, and glycine were much increased in the xylem sap. When Cu was made deficient in the nutrient solution...

The role of synovial fluid in providing nutrition to rabbit knee ligaments and menisci was evaluated by intraarticular injection of a labeled collagen precursor, tritiated proline. Incorporation of this substrate as tritiated hydroxyproline was measured in collateral and cruciate ligaments and menisci. The injectate volume (0.35 ml) did not appreciably change the overall joint pressure as measu...

Drought stress is a major factor in reduce growth, development and production of plants. Stress was applied with polyethylene glycol (PEG) 6000 and water potentials were: zero (control), -0.15 (PEG 10%), -0.49 (PEG 20%), -1.03 (PEG 30%) and -1.76 (PEG40%) MPa. The solutes accumulation of two maize (Zea mays L.) cultivars -704 and 301were determined after drought stress. In our experiments, a hi...

Salinity is a major yield reducing factor in coastal as well as arid irrigated rice production systems. Salt induced abiotic stress is an acute problem, interrupting the metabolic processes of plants, resulting in reduced growth and productivity. Proline is an amino acid which increases in plants under abiotic stress. Salinity stress affects the metabolism of plants leading to severe crop damag...
