MN DEFICIENCY AND FOLIAR ANALYSIS IN CONTAINER-GROWN YOUNG APPLE PLANTS. |
| Authors: | P. Fiorino, M. Tattini |
| Abstract:
In young apple plants (cv "Golden Delicious"), container-grown and fertilized by fertirrigation, a chlorosis apparently due to Mn-deficiency was observed; it involved 20–25% of plants, independently of the type of nutritive solution supplied. The analysis did not evidentiate substantial differences, as to the content of this element, between chlorotic and normal apical leaves. The non-homogeneity of the leaves sample used induced us to utilize as reference parameter the foliar surface. It followed a confirmation of the Mn-deficiency, while it appeared that the nature of the chlorosis might also be attributed to Zn and Mg. | |
