The majority of my research has focused on growth and physiological responses of plants to water deficits under both greenhouse and field conditions. In so doing, I concentrate on the integration of physiological responses from the organ to the whole plant level. In particular, I focus on root responses to localized water, hydraulic redistribution, and herbivory all important issues surrounding woody ornamental horticultural crops. My lab investigates inherent root-system growth patterns in heterogeneous environments as often found in both containerized and field grown plant material. One major question my research aims to address is "how does water stress influence root allocation and survivorship along a gradient in whole plant water stress severity? " Particularly, how does localized water stress affect individual roots? A complementary component of my research deals with the effects of insect feeding on root population dynamics and function. Plant herbivory can cause severe loss of plant biomass as well as impair physiological function and cause shifts in carbon allocation. Differences in root system growth rate may affect the mechanism by which plants deal with herbivory including, diminished frequency of root infection due to high root growth rates or temporal avoidance. Thus, understanding how plants respond to herbivore pressure strengthens our ability to manage plant-herbivore interactions.
