Sugar beet (Beta vulgaris L.) - one of the most important crop in the world.
In Kazakhstan, it is a traditional and major source of domestic sugar. The
industry of cultivation and production of sugar beet is one of the priority
areas of agricultural development of the country. In this paper, we studied
the regeneration ability of different genotypes of sugar beet explants on
selective media with the culture filtrate of the pathogen fungus F. oxysporum
var. orthoceras. From the roots and shoots of sugar beet the pathogen
Fusarium root rot was isolated. Was obtained pure cultures of the isolated
pathogen. As a result, of morphological and cultural descriptions, as well as
microbiological analysis it was revealed that the isolated pathogen is
Fusarium Oxysporum. The results showed the pathogenicity of the fungus. For
regeneration in vitro of the sugar beet genotypes resistant to the pathogen
the culture media was optimized to the culture filtrate of the fungus F.
oxysporum var. orthoceras. The frequency of shoot regeneration, depending on
the genotype, was 1,0-12,5 %. On these explants the multiple shoot formations
were observed.
Sainfoin (Onobrychis Mill.) is a valuable forage plant of the legume family
(Fabaceae). In Kazakhstan the sainfoin introduced as field fodder in the 50s
of the XX century and because of its biological features widely spread as a
promising crop for forage resources increasing. The electrophoresis of seed
storage proteins of Onobrychis viciifolia, Onobrychis arenaria and Onobrychis
transcaucasica species was carried out. Considerable diversity of the number,
mobility and intensity of components was determined.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
