Abstract
The absorption and translocation of 65Zn by Satsuma orange leaves have been investigated. It was found that zinc was readily absorbed by the leaves and addition of calcium hydroxide to zinc solutions resulted in a marked reduction in absorption of zinc. Addition of other elements like boron, molybdenum, magnesium and manganese exhibited a quite irregular trend in inhibition or acceleration of zinc absorption. The absorption in the presence of EDTA was inhibited tremendously, whereas the translocation of absorbed zinc within the tissue was accelerated remarkably. Further, in the presence of a fruit, there was a notable accumulation of translocated zinc in the fruit, proving the formation of strong“sink”to zinc.
