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