Brachypodium sylvaticum: Developing a new model to study freezing tolerance in perennial grasses
The interest in perennial crops is increasing. In temperate climates, perennial grasses may be exposed to freezing stress, an important cause of crop damages and subsequent economic losses in Quebec. Our results suggest that some accessions of B. sylvaticum, a model plant and perennial grass, can cold-acclimate and subsequently acquire tolerance to freezing. B. sylvaticum is a powerful tool for the study these mechanisms in perennial grasses.

Predictive equations of forage nutritive value for use under Qu茅bec鈥檚 environmental conditions
The objective of my project has been to provide agricultural producers in Qu茅bec with a simple tool to help them determine the optimal time to harvest their forage crops. We tested the suitability of predictive equations developed in the United States for predicting forage nutritive value of alfalfa-grass mixtures in the Province of Qu茅bec. We found that some of the equations were directly applicable to Quebec, while others had to be modified to meet regional needs.

The effect of plant defense phytohormones on caterpillar herbivores
To protect themselves against caterpillar herbivory, plants activate the jasmonate (JA) biosynthetic pathway leading to the induction of defense compounds. My research focuses on determining the effect of defense phytohormones in the JA pathway on the development, mortality and pupal weight of the cabbage looper, Trichopluia ni, a facultative specialist on plants in the Brassicaceae family, and the beet armyworm, Spodoptera exigua, a generalist.
