FIGUEIREDO, Guilherme Grodzki O.; LOPES, Valéria Rosa; B. FILHO, João Carlos  and  DAROS, Edelclaiton. Effect of substrates and plant growth promoting bacteria in the germination of sugarcane seeds. Rev. de Ciências Agrárias [online]. 2013, vol.36, n.4, pp.447-454. ISSN 0871-018X.

The aim of this work was to test different substrates with Plant Growth Promoting Bacteria (PGPB) inoculation on sugarcane seed germination. The substrates were sand, vermiculite and Plantmax®. The completely randomized factorial design 2x3, with 4 repetitions was used. The parameters estimated were speed of germination index, days for emergence, and 30 days after sowing the parameters: height of seedlings (cm), volume of roots (cm³), length of roots (cm), and the number of germinated plants. The application of PGPB promoted better development of seedlings, mainly roots. The Plantmax® presented the better conditions for germination and seedling development. Vermiculite had the worst results. No response to PGPB was observed in the sand. The use of Plantmax® and PGPB in germination of sugarcane seeds is recommended.

Keywords : PGPB; vigor; Saccharum spp.; seedling; Plantmax®.
