Abstract: | Summary Boron, copper, iron, manganese and zinc concentrations were measured in sunflower leaves from plants grown hydroponically
in a closed continuous flow system and with boron concentrations ranging from deficient to toxic.
Leaves were analyzed at the stage of flower development. There was a highly significant inverse correlation between B concentration
in solution and Mn concentration in leaves.
Cu, Fe and Zn concentrations in the leaves were not changed by the different B levels, although the B concentration in leaves
increased with an increasing concentration in solution, showing a close correlation each other. |
