Energy Stress in Relation to Germinability and Virulence of Root Infecting Fungi
A potentially important aspect of the survival of fungal propagules in soil is the effect of microbial (energy) stress on propagule vigor. The more rapidly propagule reserves are depleted by exudation and respiration during incubation in soil, the greater their debilitation would be expected to be. The stress imposed by the activity of soil microorganisms has been shown to result in accelerated nutrient deprivation, which may lead to decreased germinability (Adams et al., 1968; Bristow and Lockwood, 1975; Filonow and Lockwood, 1983; Hsu and Lockwood, 1973; Ko and Lockwood, 1967), attenuated virulence (Arora et al., 1985; Filonow et al., 1983), and death (Bristow and Lockwood, 1975).
