LABORATORIO DE ECOFISIOLOGÍA DEL ESTRÉS ABIÓTICO EN PLANTAS

El objetivo general del laboratorio es el estudio de mecanismos ecofisiológicos relacionados con los efectos y respuestas al estrés abiótico (i.e. inundaciones, sequía, salinidad, defoliación, deficits nutricionales), ocurriendo de manera aislada, combinada o secuencial, en plantas de interés agronómico.
Abordamos preguntas de interés y novedad en relación a la tolerancia del estrés abiótico en parámetros asociados con la germinación y desarrollo de plántulas, respuestas ecofisiológicas de plantas adultas y parámetros productivos a nivel de canopeo asociados con la supervivencia al estrés, la recuperación de las tasas de crecimiento post-estrés y la persistencia de las plantas en ambientes con limitaciones.
