The aim of this study was to evaluate the effects of the plant growth-promoting rhizobacteria (PGPR) Azospirillum brasilense Sp245 on vegetative development and phenological changes of young grape plants Vitis vinifera L. cv. ‘Colorino’ grafted onto two rootstocks 420A and 157/11 (V. berlandieri x V. riparia). Roots of the grapevine rootstocks were immersed in a bacterial suspension in water (107 CFU/mL) by dipping overnight, and transplanted into pots. The inoculated plants were distributed in two groups differently treated adding a fixed volume of inoculum: the first group received only one treatment (end of May), the second group was treated three times, from the end of May to July. Overall results revealed that A. brasilense Sp245 seems to have considerable potential in enhancing the root apparatus, vegetative development and plant survival.
