Impact of Preconditioning Temperature and Duration Period on Carpogenic Germination of Diverse Populations in Southwestern Australia.

The soilborne pathogen (Lib.) de Bary is the causal agent of Sclerotinia stem rot, a severe disease of broad-leaf crops including canola/rapeseed () that can result in significant yield losses. Sclerotia, the hard melanized resting structure of the pathogen, requires preconditioning before carpogenic germination can occur.
