Isolation sources of micro and macro elements among connection rice samples the creation of drought-resistant forms

Metals content affects not only for nutritional value of plants, but also their resistance to stress. So it was revealed that cationic composition changes hydration cytoplasm. Hydration cytoplasm positively correlated with alkali metals, a representative which is potassium, and negatively amount alkaline earth metals (calcium, magnesium). Variability rice collection samples in terms sodium, calcium, magnesium, ammonium cations has been studied. Sources are recommended be used breeding programs the creation drought-resistant forms highlighted. The potassium varied from 40 90%. In 18 samples, its did exceed 70%, 13 above 80%, makes possible recommend them as sources these trait: Olymp, Ivushka, Dozhdik, Berezka, Rapan, Aurora, Fisht. study relationship between showed presence sodium - 0.87, 0.45, calcium magnesium 0.35.
