Efeito das deficiencias de macro e micronutrientes na composicao mineral do cupuacuzeiro (Theobroma grandiflorum)


, : Efeito das deficiencias de macro e micronutrientes na composicao mineral do cupuacuzeiro (Theobroma grandiflorum). Cientifica (Jaboticabal) 26(1-2): 95-111

This experiment was carried out to study the effects of nutrient deficiencies on the mineral composition of leaves of Theobroma grandiflorum, and to estimate the content of both macro and micronutrients in the organs of plants grown in nutrient solution. It was shown that whenever a given element was not added to the substrate there was, in general, a decrease in its leaf concentration. Several interactions were found, namely: KXCa, KXMg and FeXMn.
