salinity is the major limiting factor for plant growth and crop productivity. salt stress is effective on physiological characteristics, morphology, anatomy, chemical composition and water content of plant tissue. pulses are the second of food source after the cereals for human. among the pulses, the bean has special importance. in order to investigate the effect of silicon on the physiological...

We have analyzed the nature of RecA protein-RecA protein interactions using an affinity column prepared by coupling RecA protein to an agarose support. When radiolabeled soluble proteins from Escherichia coli are applied to this column, only the labeled RecA protein from the extract was selectively retained and bound tightly to the affinity column. Efficient binding of purified 35S-labeled RecA...

Reactive oxygen spesies merupakan radikal bebas yang apabila jumlahnya berlebih akan menyebabkan stres oksidatif. dapat dihilangkan dengan pemberian antioksidan enzim, seperti enzim superoksida dismutase. Tanaman memiliki aktivitas dismutase salah satunya adalah temu hitam (Curcuma aeruginosa Roxb.). Penelitian ini bertujuan untuk mengetahui kadar protein total dan persen inhibisi ekstrak kasar...

in order to study the yield and forage quality of intercropping barley (hordeum vulgare) and mustard (sinapis alba) in different planting dates, a factorial experiment based on randomized completely block design with three replications was carried out at farm research station, gonbad -e- qabus university. factors were included as three planting dates (15 november, 6 and 20 december 2006) and fo...

Borage is an important medicinal plant which must be cultivated commercially in order to meet the ever-increasing demand for pharmaceutical industry. This study was done under hydroponics condition. Seeds of Borage were obtained from Neka Research Center (North of Iran). After applying Benomyl fungicide, the seeds were rinsed with distilled water and planted in vermiculite. After germination an...

Objective: Salt stress is a world-wide problem and soil salinity is common in arid and semi-arid regions. This study was undertaken to investigate salt tolerance in Salsola orientalis in laboratory and natural conditions and recognize the mechanisms that allow it to tolerate these conditions. Methods: This study had two parts of greenhouse and natural habitats. The treatment s...

The low-level salt waste (LAW) associated with the production of nuclear materials at US Department of Energy (DOE) facilities will be disposed of in shallow land burial sites managed by the DOE. Two of the primary contaminants of interest are Tc-99 and I-129, both soluble and long-lived radionuclides. Cs-137, a short-lived, strong gamma emitter is also a soluble contaminant of concern. In addi...
