| Summary: | The effects of rhizobacteria inoculation in
modified MS medium containing boron (1 and 10 lM) on
the biochemical components, physiological characteristics
and mineral content of the in vitro banana plantlets were
carried out. The presence of rhizobacteria in the medium
supplemented with boron at two concentrations: 1 and
10 lM resulted in an improvement in growth and root
biomass compared to the control (uninoculated). Rhizobacteria
inoculation also produced an increase in protein,
nitrate, soluble nitrogen and chlorophyll contents of the
plantlets cultured in MS modified medium containing
boron. An increase in percentage of growth ([295%) was
shown when boron was applied into medium inoculated
with Bacillus sphaericus UPMB10. The effectiveness of inoculation is increased when associated with boron,
nitrogen or carbon into the medium. Thus, these bacterial
strains could be used as a bioenhancer for growth of in
vitro banana plantlets. |
