Co-inoculation of Anabaena cylindrica and Azospirillum brasilense during initial growth and chloroplast pigments of corn

ABSTRACT Although the isolated effects of cyanobacteria Anabaena cylindrica and bacteria Azospirillum brasilense are well-known, co-inoculation both can promote other benefits to corn plants’ biological nitrogen fixation growth. The aim was evaluate initial growth chloroplast pigment levels hybrids co-inoculated with A. cylindrica. experiment conducted in greenhouse conditions using completely randomized design a factorial scheme 2 × 4 two hybrids, Balu 184 280 Pro, four inoculation treatments: no inoculation, cylindrica, brasilense, + brasilense. Co-inoculation resulted higher root dry mass aerial part hybrids; however, hybrid Pro presented responsivity. increased without altering photosynthetic levels.
