Abstract
Germination of conidia of Curvularia geniculata from 20-, 40-, and 60-day-old cultures increased as temperature was increased to 15C. At 25C, maximum germination occurred among conidia from 20-day-old cultures, but germination from 40- and 60-day-old cultures decreased at and above 25C. Number and length of germ tubes and primary germ-tube branches increased on all conidia as temperature was increased from 5C to 25C and decreased above 25C. Germination also was influenced by culture age. Total and rate of germination decreased among conidia from older cultures at all temperatures; number and length of germ tubes and germ-tube branches also decreased on conidia from older cultures. Pathogenicity of C. geniculata was not clearly established.
