Abstracts |
In a two-year fi eld experiment we used leaf analysis to evaluate the eff ect of arbuscular mycorrhizal (AM) fungi on the content of some macro elements (N, P, K, Ca, Mg) and micro elements (Zn, Mn, Fe) in grapevine leaves at the beginning of so ening/veraison of grape berries. The contents of the individual elements diff ered which was caused both by the diff erent varieties of Rulandské modré (Pinot Noir) and Frankovka (Blaufränkisch), and by the eff ect of the conditions of the year (2010, 2011), and by the actual treatment of the experiment (untreated control, mycorrhizal /AM/ plants). In 2010 the contents of all the nutrients in leaves of the variety Rulandské modré (Pinot Noir) were optimal with the exception of the contents of Ca and Mg in 2011 and content of K in 2010. In the mycorrhizal plants in both years only calcium increased signifi cantly (3.50 % as against 3.29 % and 1.54 % as against 1.31 %, respectively). The contents of micro elements in the variety Rulandské modré (Pinot Noir) fl uctuated irregularly; only the content of Mn was higher in the control treatment in both years. The variety Frankovka (Blaufränkisch) showed a small to great Ca defi cit in the leaves in both years; in 2010 also a K defi cit and in 2011 a defi cit in Mg. The contents of N, K and Mn increased signifi cantly in the mycorrhizal treated plants both in 2010 and in 2011. |
