Determining Resistance to Soft-Rot Fungi

摘要

A laboratory procedure is outlined that incorporates techniques found to promote soft rot by several fungi. This procedure employs either an agar or a soil substrate. Also presented are the principal findings of experiments underlying the procedure. Results of tests conducted according to the suggested procedure are illustrated. The overall decay resistance of the softwoods typically was greater than that of hardwoods. The levels of decay in softwoods, however, were substantially higher than previously obtained. There was a tendency for decay in soil to be somewhat greater than on agar; however, a particular preference for either substrate was indicated only in a few instances. (Author)
