Rhizobacteria in growth and quality of açaí seedlings

Abstract The success of any plant development relies on healthy and vigorous seedlings, the use rhizobacteria is a sustainable alternative for production high-quality seedlings as they positively interfere in development. Thus, objective this study was to evaluate effect growth quality açaí (Euterpe oleracea Mart.), native palm Brazil, which has significant ornamental value addition ecological economic role, mainly by providing sweet heart fruit pulp. experimental design entirely randomized. There were five treatments (Bacillus subtilis, Bacillus megaterium, amyloliquefaciens Azospirillum brasilense plus absence microorganisms - control); four replicates ten plants per plot. following characteristics evaluated: shoot height (cm), root length (cm); stem diameter (mm); number leaves; leaf area (cm2); shoot, well total dry matter (g). Shoot/root ratio determined Dickson Quality Index. data submitted variance analysis means compared using Tukey’s test at 5% probability. Pearson’s correlation matrix also determined. rhizobacterium subtilis provided higher while lower seedlings.
