Effects of Jatropha curcas oil inLactuca sativa root tip bioassays Anais da ABC (AABC)
ANDRADE-VIEIRA,LARISSA F.; BOTELHO,CAROLINA M.; LAVIOLA,BRUNO G.; PALMIERI,MARCEL J.; PRAÇA-FONTES,MILENE M..
Jatropha curcas L. (Euphorbiaceae) is important for biofuel production and as a feed ingredient for animal. However, the presence of phorbol esters in the oil and cake renders the seeds toxic. The toxicity ofJ. curcas oil is currently assessed by testing in animals, leading to their death. The identification of toxic and nontoxic improved varieties is important for the safe use of J. curcas seeds and byproducts to avoid their environmental toxicity. Hence, the aim of this study was to propose a short-term bioassay using a plant as a model to screen the toxicity of J. curcas oil without the need to sacrifice any animals. The toxicity of J. curcas oil was evident in germination, root elongation and chromosomal aberration tests in Lactuca sativa. It was...
