Response of corn (Zes mays L.) genotypes to boron fertilizatoin

Although 75 years have passed since that first evidence that boron (B) is an essential element for higher plants (Warington 1923), a definitive primary function of B in plants in not yet clearly revealed. B shows some of the most distinct and typical effects on cell elongation and cell division, tissue differentiation, menbrane permeability, pollen germination and pollen tube growth (Marschner 1990). In general, low B contents in soil are in connection with high levels of Ca, while B toxicity is a common problem in arid and semiarid regions of the world (Gupta 1979). B supply could be especially important for seed production of crops including those of moderate B needs, for example corn. Because of considerable response of plant genotypes to B (Mozafara 1989), we tested response of five corn genotypes to B fertilization. They were found considerable response of corn to B fertilization both on the level of genotypes and soil types. We recommend B fertilization for seed-corn crop, especially under conditions of moderate B supplies and/or growing of more susceptible genotypes.
