The dynamics of preheating after inflation has not been clearly understood yet.In particular, the issue of the generation of metric perturbations during preheating on super-horizon scale is still unsettled. Large scale perturbations may leave an imprint on the cosmic microwave background, or may become seeds for generation of primordial black holes. Hence, in order to make a connection between ...

Reactive oxygen species cause to release of dormancy in many plants such as sunflower seeds. This study investigated in order to evaluation role of reactive oxygen species germination and lipid proxidation in sunflower seeds. This study was performed in two separate experiments, each in a completely randomized design with factorial design with four replications.  In both experiments, uses from ...

in order to evaluate genetic diversity among squash landraces from northwest iran by morphological and physiological traits, 18 squash landraces belong to pumpkin, ornamental and confectionary groups were planted in completely randomized block design with three replications in agricultural research center of urmia in 2013. morphological characteristics related of fruit, seed, leave and flower a...

BACKGROUND: The active oxygen species, despite the damaging effects they have useful roles in the body are living things. OBJECTIVES: This research was done to determine whether Reactive Oxygen Species (ROS) could mediate Cyanide and Methylviologen signal in seed dormancy alleviation and sunflower seed germination, more widely, to assess their putative ro...

sesame (sesamum indicum l.) seed and oil have long been used widely as healthy foods to supply energy and prevent aging. some of the main active anti-oxidative constituents in sesame seeds are γ-tocopherol and phenols. the purpose of this study was to investigate the relationship between roasting temperature and time with γ-tocopherol and total phenolic compounds (tpc) of sesame seeds when roas...
