Initial Development of Hymeneae courbaril (Linnaeus.) (FABACEAE) under inoculation of edophytic bacteria from Bacillus and Herbaspirillum genus / Desenvolvimento inicial de Hymeneae courbaril (Linnaeus.) (FABACEAE) sob inoculação de bactérias endofíticas dos gêneros Bacillus e Herbaspirillum

Abstract

The rise of environmental problems and the need for recovery of degraded areas have caused interest in the knowledge of native Brazilian species. One of the major barriers to replanting native forests is the production of seedlings of species that can fuel reforestation programs. Hymenaea courbaril is a forest species, has great forest and environmental importance and is very suitable for plants in degraded areas, which can be restored by vegetation, recommended for silvipastoral, pasture afforestation and others. One of the major barriers to replanting native forests is the production of seedlings of species that can fuel reforestation programs. One solution is how growth promoting bacteria that are part of the plant's resident population and are not phytopathogenic. These bacteria can be used to treat micropropagated seeds, explants and seedlings incorporated into the plant substrate. Thus, due to the lack of studies with growth-promoting bacteria in tree species, the aim of this work is to evaluate or development of H. courbaril seedlings. Inoculants are inoculated with growth-promoting endophytes using biometric parameters such as plant size. collection, leaf number, plant height, root system length, biomass and dry matter of shoot and root system. In general the bacteria Herbaspirillum sp. the best result was obtained when an inoculation directly in the soil, presenting greater development of biometric characters. For the genus Bacillus sp. seed inoculation provided further development of the plants. This study contributes to future research and recommends the use of microbial agents to promote H. courbaril growth.
