Subjects of research: Crambe orientalis L. - mczoserophyte type perennial polycarpic grassy plant of family Brassicaceae.
Purpose of work: investigation of the biological features of eastern spurdog and estimation of the possibilities their cultivation in the condition of South Near Aral sea region.
Methods of research: traditional methods of ontogenesis, morphogenesis, flowering specifics, seed efficiency and introduction successfulness evaluation study were used in the dissertation.
The results obtained and their novelty: firstly, the characteristics of eastern spurdog growing in Karakalpakstan conditions were determined. I was marked, that it has relatively high (38-40%) index of ground germination at autumn seeding. It was established, that in the plant culture full cycle of ontogenesis development is being passed and begins generative period at 2-nd and 3-rd year of vegetation. Features of phenology, anthccology, fructification, seed efficiency and chemical composition at South Near Aral sea region conditions were determined.
Practical value: the obtained results have importance at creation of artificial eastern spurdog agrophytoccnoses at arid conditions of Karakalpakstan. Eastern spurdog may be successfully used as feed, medicinal, melliferous and decorative plant.
The obtained results may be also applied at lecture on botanical disciplines for students of high educational institutions and during writing of textbooks and monography.
Degree of embed and economic effectivity: the results arc used at lectures on “Botany”, “Geobotany”, “Ecology and protection of nature”, “Ecology of plants” at the Nukus State pedagogical institute (act №1, 25.01.2010), at Nukus municipal administration of rehabilitation and verdurization (act from 14.02.2010), at Association of Republic of Karakalpakstan farmers (act №1, 25.02.2010), at Mahpakul farmer association of Tahtakupir region (act №4, 5.03.2010).
Field of application: introduction, ecology, biology.
