Rhizobia and associative bacteria promote growth in rice plants
(Oryza sativa L.) through a series of mechanisms, but most studies on inoculation have
been performed based on inoculation with these bacteria in a separate or singular manner.
The objective of this study was to assess the efficiency of single/isolated inoculation and
inoculation combined with symbiotic rhizobia from forage legume and with Azospirillum
brasilense on promoting growth and the root colonization process in wetland rice. Two
rhizobia among four isolates from a greenhouse and a laboratory experiment were
selected that efficiently promoted seed germination and rice plant growth in a sterilized
substrate and in soil. The two most efficient isolates (UFRGS Vp16 and UFRGS Lc348) were
inoculated alone or in combination with a commercial product containing A. brasilense
in two field experiments using two wetland rice cultivars over two growing seasons. In
the field experiments, these isolates coinoculated with A. brasilense promoted larger
increases in the agronomic variables of wetland rice compared to the control without
inoculation. Confocal laser microscopy confirmed the presence of inoculated bacteria
tagged with gfp (UFRGS Vp16, UFRGS Lc348, and A. brasilense) colonizing the root
surface of the rice seedlings, mainly in the root hairs and lateral roots. |
