PGPR mediated Zinc biofertilization of soil and its impact on growth and productivity of wheat

Objectives: This study describes Zinc biofortification of wheat using a rhizospheric isolate, Pseudomonas fluorescens strain Psd. Methods: The strain was used as a bio-ionculant in soil deficient in zinc and the plant-growth promoting potential and biofortification was assessed using a number of phy...

Methods: The strain was used as a bio-ionculant in soil deficient in zinc and the plant-growth promoting potential and biofortification was assessed using a number of physical and biochemical parameters.

The application of a Zn-laden biomass of the strain in soil resulted in increased growth and productivity of wheat crop as demonstrated by pot experiments. The beneficial effect was also reflected in increased activities of some enzymes. In addition, grain Zn2+ content was enhanced by ~85% in comparison to wheat grown in Zn2+-deficient soil.info:eu-repo/semantics/openAccessChilean Society of Soil Science / Sociedad Chilena de la Ciencia del SueloJournal of soil science and plant nutrition v.15 n.1 20152015-03-01text/htmlhttp://www.scielo.cl/scielo.php?script=sci_arttext&pid=S0718-95162015000100017en10.4067/S0718-95162015005000017
