          Abstract

          A análise das folhas das plantas revelaram que a absorção de Mg e de K aumentaram com a concentração do elemento respectivo na solução. O Mg não interferiu na absorção do K nos tratamentos correspondentes à omissão e dose 2 deste nutriente; nos tratamentos correspondentes à dose 1, 48 p.p.m. de Mg nas, soluções nutritivas estimularam a absorção de K. O K inibiu a absprção de Mg nos tratamentos correspondentes às doses 0 e 2 deste elemento: quanto na presença da dose 1, 234, p.p.m. de K nas soluções nutritivas determinaram maior concentração de Mg nas folhas. O K teve ação antagônica sobre o Ca; o Mg teve efeito semelhante só quando na presença da dose mais elevada de K. Na ausência desse elemento ou na presença de 234 p.p.m. dele o efeito do Mg foi quadrático.

          Translated abstract

          The present paper presents the results of a factorial experiment, Mg/K in hydroponic cultures in order to study the absorption on both elements by citrus trees. The treatments consisted of: Magnesium did not interfer with the content of K in the leaves when K was omitted or present in the nutrient solution at level 2 (704 p.p.m.). Magnesium in the nutrient solution (48 ppm) stimulated K absorption. Magnesium absorption was inhibited when K was present in the nutrient solution at levels 0 and 2. At level 1 (234 p.p.m. of K) there was an increase in Mg content in the leaves. Potassium-calcium antagonism was observed in all cases wheresas Mg-Ca antagonism was observed only the presence of higher levels of K. In the absence or presence 234 p.p.m. of K a quadratic effect of Mg was observed.
