摘要

Lecythis pisonisCambess, popularly known as sapucaia, has great economic and socio-environmental potential. The objective of this study was to evaluate the establishment andin vitromorphogenesis ofL. pisonisunder the effect of disinfecting agents, plant growth regulators, and thermal stress. The study was divided into three experiments: (i) development of the disinfection protocol by testing different concentrations and times of exposure to sodium hypochlorite (NaOCl) and different concentrations and methods of amoxicillin application, (ii)in vitrobudding induction by testing different concentrations of 6-benzylaminopurine (BAP) or kinetin (KIN) supplemented to Woody Plant Medium (WPM) and Murashige and Skoog (MS) culture media, and (iii)in vitroformation from plantlets by analyzing different concentrations of indole-3-butyric acid (IBA) with different exposure times to a thermal stress of 40 degrees C. The disinfection of stem segments was effective using 3% NaOCl and 3.0 g L(-1)amoxicillin solution. MS culture medium supplemented with 0.25 mg L(-1)BAP induced more shootsin vitro. One milligram per liter IBA promoted greater rootingin vitro, and it is not necessary for thermal stress tolerance.
