Foliar-application of Bacillus cereus caused some numerical, but not significant, differences in photosynthesis, stomatal conductance and transpiration. Dry matter accumulation was significantly influenced with reproductive organs being favored. Increases in various metabolites were also recorded, noticeably in myo-inositol. The bacterium seems to effectively influencing plant metabolism and growth resulting in improved carbohydrate partitioning to the reproductive structures. The mode of action appears to be via metabolites produced by the bacterium influencing the biochemistry of the leaf, particularly carbohydrate relationships, culminating in improved efficiency of translocation to the major sinks. The end product is improved dry matter partitioning to the fruit.
