Abstract: | Responses to availability of nutrients vary between different species within the same genus, mainly because the different nutritional requirements, absorption capacity, translocation and use of nutrients, The purpose of this study was to evaluate the efficiency of absorption, translocation and use of micronutrients by different cultivars of Coffea arabica L. grafted into Apoatã IAC 2258 (Coffea canephora). The experiment was conducted in a greenhouse using cultivation in nutrient solution in a 7 x 3 + 2 factorial design: seven cultivars of Coffea arabica L. (Palma II, Catucaí 2 SL, Oeiras MG 6851, Obatã IAC 1669-20, Acauã, Topázio MG 1190 and Paraíso MG H 419-1), three types of seedlings (ungrafted, self-grafted and grafted on cultivar Apoatã IAC 2258) and two controls (Apoatã self-grafted and Apoatã foot-free). The results showed that the rootstocknegatively influenced the absorption of boron, iron and manganese. The translocation of the micronutrients boron and copper had the highest rates in the grafted seedlings. The cultivar Palma II, when grafted, showed the highest rates of use of nutrients, showing that it can be grafted. The rootstock proved to be suitable for grafting, for not being negatively influenced by both the grafting and the cultivars used. |
