✦ Synopsis
The investigations on the nutritional requirements of the latent phase of Ceratocystis paradoxa causing ripe pineapple fruit rots were studied. The glucose, total protein and calcium ions levels were higher in ripe fruits than in unripe fruits. However, the ascorbic acid content was lower in the ripe fruits. All the carbon and nitrogenous compounds tested supported the growth of the fungus with D-glucose and casein hydrolysate providing the best carbon and nitrogenous snurceq respectively. The boiled extracts of unripe fruit rind at 60 "C and 80 "C were inhibitory to conidia germination. The carbohydrate and nitrogenous infusions at 1 "6 and 3 7; induced unripe pineapple fruit rots of C. paradoxa. All the infusions at 107; concentrations were inhibitory to the development of the fungal pathogen.
