The production of copper, zinc and molybdenum deficiencies in crop plants grown in sand culture with special reference to some effects of water supply and seed reserves



The production of copper, zinc and molybdenum deficiencies in crop plants grown in sand culture with special reference to some effects of water supply and seed reserves



Plant And Soil 5(3): 205-222



A method is described for the production of acute deficiencies of copper, zinc or molybdenum in large scale sand cultures, by using rainwater treated with ion-exchange resins. Visual symptoms of copper, zinc and molybdenum deficiencies in large seeded leguminous crops, and in other species are summarized. Seed reserves play an important part in the incidence of copper and molybdenum deficiencies and to a lesser extent of zinc deficiency in pea, runner bean, dwarf bean and broad bean. "Deficient" seed, obtained from plants grown in the deficiency sand cultures, was compared with seed from complete nutrient sand cultures or from field-grown plants. Seed reserves of molybdenum are usually sufficient for a complete generation but reserves of copper or zinc requirements of the plants.
