Plant measurements and analytical results of direct and indirect iron deficiency of grapevine rootstocks

Iron deficiency causes severe symptoms of leaf chlorosis with many crop species. In many cases the stess situation is induced by high lime stone content in soils. This study analyzed the response of grapevine rootstocks to no iron availability (-Fe) and a reduced iron availability (+Fe+BiC) with the aim to differentiate the response reaction. Plants were grown as woody cutting in pots filled with sand and fertilized with an half-strength Hoagland solution. Mesurements taken and data were obtained from samples collected at the end of the experiment after 4 weeks.
