Study of nutrient distribution in the rose bush for foliar diagnostic purposes
A study on the distribution of the mineral nutrients in the different parts of rose bush was carried out with the aim of chossing whichever of these might be most suitable as diagnostic tissue, the cultivar used being "Gabriela". Although for some nutrients (such as N, K) the leaf position on the stem does not seem to have a great effect on its foliar concentrations, in other cases (Ca, Mn, Cu) these concentrations vary widely according to the situation of the leaf. In general, the greatest concentration variations are noted in the youngest leaves, the maximum stability being shown by the first two leaves of 5 leaflets. This stabiliry of the mineral nutrient concentrations in these first two leaves of 5 leaflets makes suitable as samples for diagnostic purposes.
