Cultivation of immature embryos of sunflower (embryo culture) on nutrient media in conditions in vitro
The method of culture of immature embryos on sunflower is used to obtain distant hybrids, introduce desirable traits into cultivated varieties, and also to accelerate the development of new forms of this crop. Obtaining the additional generations per year can shorten the period required to bring the splitting form to a stable state. Under conditions of artificial cultivation on nutrient media it is possible to stimulate the development of the embryo bypassing the stages of rest and ripening, which can greatly accelerate the production of adult productive plants of the next generation. In studies, the possibility of obtaining sunflower plants from embryos 7, 12 and 20 days of age is considered. Differences in the frequency of plant output depending on the genotype, age of the embryo isolated from the seed and differences in the type of development of plants obtained from embryos of different ages are shown.
