Three combinations with equal grape stock (Berlandieri x x Riparia Kober 5BB) on which there were 3 different grape varieties (Red traminac, Merlot and Sauvignon) were used as objects of the investigation. On the other hand, the same grape variety (Red terminac) was applied to different stocks. A specific influence of the grape stock and of the grape variety on the concentration of ions was found. Variety had a much stronger influence on the N content in the leaves and shoots than the grape stock. Variety exerted a stronger influence on the P content in the leaves, while variety and stock had equal effects on the P content in the shoots. The grape stock exerted a stronger influence than variety on the K,Ca and Mg content in both examined plant organs, especially regarding the K content in the shoots. The content of the investigated ions in the plant material was the lowest when the nutrient solution lacked ions. The occurrence of the ion antagonism between N and K,Ca and P and Mg and P showed notably. Certain interaction was noticed among the nutrition variants, grape stocks and varieties, based on the contents in the leaves and shoots.
