Abstract/Contents:"Saprophytic growth of Bipolaris sorokiniana (Sacc. in Sorok.) Shoem. was evaluated on the four youngest, visible, detached laminae of Poa pratensis L. Non-infected laminae and laminae infected with B. sorokiniana before detachment were used in all studies. Mycelial growth and sporulation from lesions on infected laminae and on non-infected laminae infested with B. sorokiniana was influenced by whether lamina tissue was killed, method of killing, and degree of sterilization. Mycelial growth generally was rapid on both non-infected laminae and infected laminae of all ages. Sporulation was rapid on non-infected laminae of all ages, but progressively slower on each older lamina of laminae infected preceding detachment. Total sporulation was greatest on both non-infected and infected laminae that were most extensively sterilized; less extensive sterilization resulted in fewer conidia being produced on all laminae. In all instances, however, total sporulation was greater on non-infected laminae than on infected laminae. The results suggest that the transition from parasitic to sarophytic development of B. sorokiniana on P. pratensis laminae is not passive. There is an interaction between B. sorokiniana and the host tissue during the parasitic stage of the organism that results in conditions detrimental to sporulation and the number of conidia produced. Mycelial growth generally was prolific on all laminae, and it is suggested that mycelial growth on lamina tissues may constitute an important source of inoculum for primary infections in P. pratensis monocultures."
