Recent reports have underlined the potential of gamma (γ)-rays as tools for seed priming, a process used in seed industry to increase seed vigor and to enhance plant tolerance to biotic/abiotic stresses. However, the impact of γ -rays on key aspects of plant metabolism still needs to be carefully evaluated. In the present study, rice seeds were challenged with different doses of γ -rays and gro...

In order to solve problems of lower seed-filling stability and wheat seed damage mechanical shooting seed-metering device, the filling structure device was optimized. The effects movement were obtained through analysing kinematics dynamics distributor. influence factors inner diameter distributor, rotational speed distributor inclination angle window. discrete element software (DEM) used simula...

In an attempt to understand the initial stage of seed imbibition-the wetting stage-we have examined water binding in dry soybean cotyledon tissue using water sorption isotherm curves. The sorption isotherms show three levels of water affinity: a region of strongly bound water at moisture contents below 8%, a region of weakly bound water at moisture contents between 8 and 24%, and a region of ve...

OBJECTIVE Mucositis is a serious disorder of the gastrointestinal tract that results from cancer chemotherapy. We investigated the effects of increasing grape seed extract doses on the severity of chemotherapy in a rat model and its coincident impact on chemotherapeutic effectiveness in colon cancer cells. DESIGN Female Dark Agouti rats were gavaged with grape seed extract (400-1000 mg/kg) or...

The effects of grape seeds extract and grape peels extract prepared from grape pomace on the activity of antioxidant enzymes, degree of lipid peroxidation in serum and liver tissue were investigated in rabbits fed on high cholesterol diet. New Zealand white rabbits were divided as follows ; 1) NOR (normal group); 2) CHOL (cholesterol group); 3) GSH (cholesterol + grape seed extract group); 4) G...

Reactive oxygen species (ROS) are key players in the regulation of seed germination and dormancy. Although their regulated accumulation is a prerequisite for germination, the cellular basis of their action remains unknown, but very challenging to elucidate due to the lack of specificity of these compounds that can potentially react with all biomolecules. Among these, nucleic acids and proteins ...

Seeds are in a natural oxidative context leading to protein oxidation. Although inevitable for proper progression from maturation to germination, protein oxidation at high levels is detrimental and associated with seed aging. Oxidation of methionine to methionine sulfoxide is a common form of damage observed during aging in all organisms. This damage is reversible through the action of methioni...

This study was performed to investigate the effect of storage conditions on seed germination performance of faba bean (cv. Shami). For this purpose, a three factors factorial experiment was conducted in laboratory of Seed Science and Technology, Faculty of Agriculture, Yasouj University, in 2013-2014, based on CRD design with five replications.  The experimental factors were storage temperature...

The article focuses on the prevention of seed damage in a gin machine and conducts research what parameters affect damage. Based analysis scientific this area, it was established studied that density raw material roller its rotation speed, as well release fibers from working chamber are factors influencing Scientific materials acceleration turnover have been analyzed. analysis, is based obtaini...
