“…For example, exposure of S. sclerotiorum to alternating wet and dry conditions (74), desiccation (H.C. Huang, unpublished), or freezing (41) caused injury to sclerotia. These injured sclerotia germinated myceliogenically, causing infection and wilt of sunflower (50).…”

“…A completely melanized rind is needed to prevent immediate myceliogenic germination and to foster dormancy of sclerotia. Myceliogenic germination is induced, however, by the presence of nutrients, either exogenous (2) or leaked from injured sclerotia (18,39,74). Sclerotial injury occurs following alternating wet and dry conditions (74), desiccation (H.C. Huang, unpublished), or exposure to sub-freezing temperatures (41).…”

“…This leakage would facilitate the removal of nutrients, which would induce rapid colonization by soil microorganisms and subsequent decay within a couple of weeks (Smith, 1972). Similarly, in the present study submerging in flooded soil and sublethal heating of S. rolfsii sclerotia may have enhanced nutrient leakage, resulting in increased invasion by anaerobic soil bacteria as observed in the light microscopy and SEM sections.…”

“…It has been shown that drying and wetting of sclerotia causes a release of exudates that promotes attack by microorganisms (Smith, 1972). However, in this laboratory-based system there was no drying and wetting of sclerotia, which would occur naturally in field or glasshouse situations.…”
