Sugarcane plant growth promotion by P. agglomerans 33.1. The strain was added to the substrate of acclimated variety SP80-1842 (A) and SP80-3240 (B)
sugarcane. The data are the average dried weights at 30 DAI. The bars represent the standard error of each treatment. **, values in the same tissue and varieties
are significantly different ( 0.01) from the control according to Student’s t test. (C) Sugarcane variety SP80-1842 without (left) and with (right) 33.1
inoculation. (D) Sugarcane resistance protein production. a, the index of enzymatic activity was calculated on the basis of the absorbance/ml of substrate/h. * and
**, values are significantly different from the control treatment (0.05 and 0.01, respectively) according to Student’s t test.
