Abstract

The level and type of fungal infection on grains varying in hardness at different stages of development over 2 seasons was studied. Hard grains showed less incidence of grain moulds than soft grains during development. Microscopic examination showed more intense deposition of protein bodies in hard than in the soft grains. The presence of fungal hyphae in the endosperm of soft grains and pitted starch granules was clearly visible microscopically. Extracts of immature and mature hard and soft endosperm were inhibitory to Fusarium moniliforme growth. These inhibitors were heat labile and non-dialysable indicating that protein factors may be involved. The activities of inhibitors to serine proteinases were comparatively higher in endosperm of hard grains during development. The endosperm of hard grains contained more protein and prolamine than that of soft grains. A role for proteins in resistance of fungal infection in low tannin lines is presented.
