ABSTRACT
Jasmonic acid is a native plant growth regulator produced by algae, microorganisms and higher plants. This regulator is involved in the activation of defence mechanisms against pathogens and wounding in plants. Studies concerning the effects of carbon: nitrogen ratio (C/Nr: 17, 35 and 70), type of inoculum (spores or mycelium) and the yeast extract addition in the media on jasmonic acid production by Botryodiplodia theobromae were evaluated. Jasmonic acid production was stimulated at the carbon: nitrogen ratio of 17. Jasmonic acid productivity was higher in the media inoculated with mycelium and in the media with yeast extract 1.7 and 1.3 times, respectively.

El ácido jasmónico es un regulador del crecimiento de las plantas producidopor algas, microorganismos y plantas superiores, que participa en laactivación de mecanismos de defensa contra patógenos y ante la presenciade heridas en las plantas. En este trabajo se estudió la influencia de larelación carbono:nitrógeno (rC/N: 17, 35 y 70), el tipo de inóculo (esporas omicelio) y la adición de extracto de levadura al medio de cultivo en laproducción de ácido jasmónico por Botryodiplodia theobromae. Los estudiosrevelaron que la producción de ácido jasmónico es estimulada a una rC/N 17.La productividad del ácido jasmónico fue mayor para la inoculación conmicelio y la adición de extracto de levadura al medio de cultivo en 1,7 y 1,3veces, respectivamente(AU)
