Abstract
Yao, B., and Tuite, J. 1989. The effects of heat treatment and inoculum concentration on growth and sporulation of Penicillium spp. on corn genotypes in storage. Phytopathology 79:1101-1104. The effects of heat treatment and inoculum concentration of Penicillium was greater for the resistant hybrids but the disease rankings among the brevi-compactum, P. cyclopium, and P. viridicatum on storability of corn genotypes remained. The heat-treated resistant hybrids did not support kernels were determined in separate tests for 10 genotypes of dent corn significantly more sporulation of Penicillium than the unheated, susand a visual flint (VF) selection. Hand-shelled corn grown during ceptible genotypes. In three tests, a total of I I corn genotypes were 1983-1985 was used. Kernels of B73 X Mo17 and Dekalb XL67, resistant, inoculated with 2 X 10' to l04 or 2 X 103 to l0' spores of Penicillium and H95 very susceptible and VF, moderately susceptible to storage spp. per gram of corn and stored at 13-14 C and 88% RH. Increasing Penicillia were heated at 80 C for 20 min, then inoculated with 2 X 103 the inoculum to either 104 or l05 spores/g generally had no significant spores/g and stored at 88% RH and 14 C for 49 days. Host reaction effect on relative resistance as measured by propagules and visible mold, was determined by a visible mold rating on individual kernels and number although there was an increase in propagules with an increase in the of propagules isolated after dilution on a modified potato-dextrose agar. amount of inoculum, particularly when 2 X 104 or 10 spores/g was used. Molding was substantially increased by the heat treatment as measured There appeared to be a more defined separation of hybrids with inoculum by propagules and less so by visible mold for all four genotypes. Increase at 2 X 104 and 105 than at 2 X 103 spores/g. Additional keywords: maize, storage molds.
