Sažetak
The possibility of substituting ions has lately been given particular attention; the possibility of total and partial substitution of Rb for K, Sr for Ca, and Na for K, has often been mentioned.
We have investigated the possibility of a total substitution of Sr for Ca and K in the following plant species: maize, sunflower, pea and cucumber.
The substitution of Sr for Ca and K has been investigated in comparison to three controls: complete nutritious solution, lack of K, lack of Ca in relation to the weight of dry matter and content of ions N, P, K, Ca and Sr.
According to the synthesis of organic matter of the overground part the results show that the substitution of Sr for Ca was the most effective in maize, next in cucumber and sunflower, while in pea a negative effect was obtained. Considering the root the situation is different, because maize and pea reacted most, sunflower was next, and least of all reacted cucumber.
An interesting fact is that it was possible to substitute Sr for K in relation to the weight of both overground part and root in pea. The other plant species, especially cucumber, do not show any effect.
The content of individual ions depends on the kind of nutrition and plant species.
