There are complexes feedback mechanisms involving the relationship rootstock/scion, whick can positively or negatively affect the plant nutrient efficiency use. The goal of the present work was to evaluate the efficiency of uptake, translocation and utilization of Zn, Cu and Mn in coffee seedlings. The experiment was carried out in a greenhouse over 170 days using circulating nutrient solution in pots with sand medium. Four Coffea arabica L. genotypes were used as grafts: Catuaí Vermelho IAC 15 and Oeiras MG […]

Studies into the nutritional efficiency of grafted coffee plants is essential for the selection of graft/rootstock combinations for a maximum development and production. Our objective was the evaluation of the influence of rootstocks on the efficiency of uptake, translocation and use of Ca, Mg, and S in young Coffee arabica L. plants in hydroponic cultivation. The experiment was conducted in a greenhouse and lasted 170 days, using sand as substratum and circulating nutritive solution. Four genotypes of Coffea arabica L. were […]
