NATURAL AUTOFLUORESCENCE IN OOSPORES OF PERONOSCLEROSPORA SORGHI AND THEIR VIABILITY

Peronosclerospora sorghi (Weston & Uppal) C.G. Shaw is a major problem for the production of sorghum (Sorghum bicolor (L.) Moench) and maize (Zea mays L.) in many parts of the world. The pathogen produces two types of spores, viz. conidia and oospores. An inverse relationship between natural aut...

Zusammenfassung:Peronosclerospora sorghi (Weston & Uppal) C.G. Shaw is a major problem for the production of sorghum (Sorghum bicolor (L.) Moench) and maize (Zea mays L.) in many parts of the world. The pathogen produces two types of spores, viz. conidia and oospores. An inverse relationship between natural autofluorescence in fungal spores and their viability was reported by Wu and Warren. The present study was undertaken to determine viability of the oospores of P. sorghi using fluorescence microscopy.
