Grapevines form associations with arbuscular mycorrhizal (AM) fungi. These root-dwelling fungi have the potential to contribute to crop vigor, productivity, pathogen protection, and nutrient content in grapes. In this study the arbuscular mycorrhizal fungal communities of grapevines and the surrounding interrow and native vegetation are compared. We found(More)
In 1993, a serious epidemic of a tomato root disease resembling corky root rot occurred in commercial greenhouses throughout Canada. Pyrenochaeta lycopersici could not be isolated from diseased roots, but Humicola fuscoatra was commonly isolated. The objectives of our work were to determine if H. fuscoatra is able to infect roots of tomato and cause corky(More)
This investigation explores the relationship between increased energy levels and leaf morphology. It tests the idea that the causal agent of development is the dissipation of energy into transformed matter. The energy under which leaves developed was modified by increasing temperatures in grape cordons through wrapping them in clear plastic sleeves in the(More)
