SCIENTIFIC BASIS OF COTTON SEED GERMINATION IN THE CENTRAL REGION OF UZBEKISTAN
The responses of cotton (Gossypium hirsutum L.) seeds to germination depend upon the point in the germination-through-emergence sequence at which seed environmental conditions conclude to promote germination and seedling development. Temperature and genotype can influence seedling vigor in upland cotton and help identify promising genotypes that could perform well under different temperature extremes. In the presented research, the nature of the development of cotton seeds largely depends on temperature conditions and the growing seasons, which provide information that determines their uniformity based on the thermal regime of germination. The physical and biological diversity of cotton seeds has close relations to the pattern of plant development and the influence of certain environmental factors on them. In the presented study, sowing seeds of three local cotton cultivars, AN-Bayaut-2, Tashkent-6, and Armugon-2, transpired on two dates (April 17 and May 10). The nature of cotton seeds’ development, largely dependent on temperature and growing season and on the thermal regime of their germination, showed different indicators. A discovery revealed that the germination of seeds decreased in areas with later-sown kernels. In terms of germination energy and other physiological functions, the best results were notable in seeds at the lower and middle stages of plant development. The cultivar AN-Bayaut-2 is adaptable to various environmental factors according to seed germination and vegetation period compared with other local cotton varieties, i.e., Tashkent-6 and Armugon-2.
期刊介绍:
The SABRAO Journal of Breeding and Genetics is an international journal of plant breeding and genetics research and was first published in 1969. It is the official publication of the Society for the Advancement of Breeding Research in Asia and Oceania (SABRAO).
Its objectives are to: promote the international exchange of research information on plant breeding and genetics, by describing new research findings, or ideas of a basic or practical nature; and be a medium for the exchange of ideas and news regarding members of the Society.
The Journal gives priority to articles that are of direct relevance to plant breeders and with emphasis on the Asian region. Invited for publication are research articles, short communications, methods, reviews, commentaries, and opinion articles. Scientific contributions are refereed and edited to international standards.
The journal publishes articles for SABRAO members mainly. The Journal preferred strongly that at least one author should be a current member of the Society. Non-members may also publish in the journal.
