Alopecurus myosuroides Huds. (black-grass) has always been a major concern for cereal growers, and the development of herbicide resistance does not improve the situation. This review article summarizes the different traits involved in the dispersal pattern of herbicide resistant black-grass individuals within a susceptible field population. Therefore, the whole life cycle of black-grass is depi...

Background: Infertility is a problem that now affects many couples that are causing the disintegration of many families and as a psychological crisis, a lot of stress on couples has been entered. Cyclosporine (CsA), a cyclic undecapeptideof fungal origin, is a powerful immunosuppressive agent that has markedly improved graft survival rates in organ transplantation. The drug has adverse side eff...

Seed mass is an adaptive trait affecting species distribution, population dynamics and community structure. In widely distributed species, variation in seed mass may reflect both genetic adaptation to local environments and adaptive phenotypic plasticity. Acknowledging the difficulty in separating these two aspects, we examined the causal relationships determining seed mass variation to better ...

Soybean seed coat exists in a range of colors from yellow, green, brown, black, to bicolor. Classical genetic analysis suggested that soybean seed color was a moderately complex trait controlled by multi-loci. However, only a couple of loci could be detected using a single biparental segregating population. In this study, a combination of association mapping and bulk segregation analysis was em...

osting by E Abstract In this investigation, the effects of Sidr honey, Nigella sativa oil (black-seed oil) and Sidr honey and black-seed oil together on the ultrastructure of tegument, gastrodermis and testes of adult male Schistosoma mansoni harbored in albino mice were studied. The tegument of adult male S. mansoni recovered from mice treated with various types of treatments revealed apparent...

Red spruce (Picea rubens Sarg.) and black spruce (Picea mariana (Mill.) B.S.P.) are genetically and morphologically similar but ecologically distinct species. We determined intraspecific seed-source and interspecific variation of red spruce and black spruce, from across the near-northern margins of their ranges, for several light-energy processing and freezing-tolerance adaptive traits. Before ...

introduction during the last decades interest in organic production of seed specially for medicinal plants take into consideration because of higher quality of organic products (hermes, 2010). seed germination is one of the principal stages in the plant life cycle and seeds with higher quality and vigour resulted in more pronounced seedlings growth and development. therefore, investigation of a...

Using the solitonic solution-generating technique we rederived the one-rotational five-dimensional black ring solution found by Emparan and Reall. The seed solution is not the Minkowski metric, which is the seed of S-rotating black ring. The obtained solution has more parameters than the Emparan and Reall’s S-rotating black ring. We found the conditions of parameters to reduce the solution to t...

The connection between dark matter and giant black holes in the galactic nuclei is investigated. The joint evolution of dark and luminous matter in averaged self-consistent gravitational potential is considered. It is shown that the distribution of dark matter remains spherically symmetric even in presence of essential asymmetry of luminous matter in the galaxy. The kinetic equation describing ...
