摘要: Rice is inherently low in micronutrients, especially iron, which leads to severe malnutrition problems rice-consuming populations. Different plant growth promoting rhizobacterial strains (PGPRs) (viz. Pseudomonas putida, fluorescens , and Azospirillum lipoferum from a microbial collection B 15, 17, 19, BN 17 30 isolated the rhizospheric soils) were applied field grown rice plants with an aim increase iron content of grains. 16S rRNA gene sequence showed that isolates belong Enterobacteria species. param eters related show enhancement upon treatment PGPRs. Treatments P. 19 almost doubled grain content. Besides this, translocation efficiency roots shoots grains was also enhanced It therefore concluded application PGPR important strategy combat problem deficiency consecutively human masses.
