Factors influencing the effects of host diversity on plant disease epidemics for wheat stripe rust and potato late blight

Creator:

Garrett, Karen A.

Abstract:

Most studies of plant disease epidemiology have focused on epidemics in host populations composed of a single genotype. But crop plant diversity can be a useful means of improving the deployment of resistance genes. In a series of experiments with wheat stripe rust and potato late blight, we studied factors...

The influence of induced host moisture stress on the growth and development of western spruce budworm and Armillaria ostoyae on grand fir seedlings

Creator:

Parks, Catherine G.

Abstract:

This greenhouse study evaluates the influence of separately and simultaneously imposed water stress, western spruce budworm (Choristorneura occidentalis Freeman) defoliation, and inoculation with the root pathogen, Armillaria ostoyae (Romagn.) Herink, on the growth and biochemical features of Abies .grandis (Dougl.) Lindi. Seedling biomass, plant moisture status, bud phenology, and allocation...
