The aim of the present study was to evaluate the antioxidant effects of aqueous fruit extract of Ziziphusjujuba on ethanol-induced oxidative stress and to examine its protective effects on sperm motility and plasma membrane integrity of male Wistar rats. Adult male rats (n = 28) were divided into four equal groups: the first group served as untreated controls, the second group of rats was given...

The inflation GI of a graph G with n(G) vertices and m(G) edges is obtained from G by replacing every vertex of degree d of G by a clique, which is isomorphic to the complete graph Kd, and each edge (xi, xj) of G is replaced by an edge (u, v) in such a way that u ∈ Xi, v ∈ Xj , and two different edges of G are replaced by non-adjacent edges of GI . The total domination number γt(G) of a graph G...

Flushing, i.e. cyclic fluctuations in fruit yield, is an important problem in sweet pepper production. These fluctuations result from cyclic variations in fruit set. Therefore, the relationship between fruit set and plant sink and source strength was investigated in several greenhouse experiments. A decrease in plant source strength by decreasing inter-plant distance or light intensity or by le...

Tropical trees may show positive density dependence in fruit set and maturation due to pollen limitation in low-density populations. However, pollen from closely related individuals in the local neighbourhood might reduce fruit set or increase fruit abortion in self-incompatible tree species. We investigated the role of neighbourhood density and genetic relatedness on individual fruit set and a...

Objective: The present study was conducted to investigate antibacterial properties of fruit and flower of Peganum harmala. Material and Methods: Column chromatography, followed by preparative thin layer chromatography (TLC) was used for final purification. The structure of pure alkaloids was determined using spectroscopic methods (1H-N...

iran is the center of origin as well as variation for pomegranate (punica granatum l.). also, iran is one of the most important countries in the world in terms of pomegranate culture and production. monitoring morphological and physiological changes which occur during fruit growth and development is an important determining in orchard management decisions. the aim of the present research was to...
