A survey of endophytic bacteria from stem of tomato cultivars under cover with or without biostimulation treatment in seedling stage was realized in order to make changes in the management of an agro-ecological transition. Late tomato production and the redesign of the handlings for hedges were two determinants in this assay. Its ability to promote plant growth in vitro was determined and crop productivity was evaluated. No direct relationship between the amount, diversity and ability to promote plant growth of tomato stem endophytes and biostimulation was found, but these features would be related to tomato genotype.The platense tomato showed a greater biodiversity of endophytic plant growth promoters comparing to the BADRO hybrid and UCO variety, but as genetic line, it was not suitable for cultivation as late tomato. Instead, the BADRO hybrid and UCO variety showed good yields and responded to biostimulation.
