En forma muy especial quiero agradecer a mi profesora patrocinante Dra. Miren Alberdi Lag,
quien me permitió desarrollar este trabajo en el laboratorio que ella dirige y de quien siempre
recibí constante ayuda tanto teórica como práctica. Quien con su constante apoyo y dedicación
contribuyó al desarrollo de esta tesis como también a la formación de un potencial hombre de
ciencia. A las profesoras integrantes de mi comisión de tesis Dra. Susan Hess F. que con sus
consejos y enseñanzas aportó a este trabajo y con ello permitió que éste llegara a buen término y
Dra. Ilona Concha Grabinger por aceptar formar parte de esta comisión.
A Nancy Ulloa (Magíster en Ciencias, mención Botánica), quien formaba parte del grupo de
trabajo y de quien aprendí mucho, con respecto a la forma de trabajar en el laboratorio y abordar
los diferentes problemas.
También merecen un reconocimiento importante, los profesores Magdalena Romero del
Instituto de Botánica, Juan Carlos Paredes y Joel Pardo del Instituto de Química de esta
Universidad, de quienes recibí tanto críticas constructivas como voces de apoyo.
Este trabajo fue realizado en el laboratorio de Ecofisiología Vegetal del Instituto de
Botánica e Instituto de Química de la Universidad Austral de Chile y fue financiado por los
proyectos: DID-UACH S-20002-88 y FONDECYT No 1000610.
