ABSTRACT

Three populations of Fusarium oxysporum were tested for their pathogenicity to tomato seedlings. The isolates were collected from three soil environments of tomato: conventional cultivation (no cover crop), in field pea mulch and in rye mulch. Tomato plants of cv. Rumba were grown in a growth chamber in standard substrate with a pathogen inoculum prepared as described by Wagner (1997) or without the fungus. Pathogenicity was determined using the disease index, and the parameters of chlorophyll fluorescence were measured with PAM fluorometer. Results proved the effect of cover crops on F. oxysporum pathogenicity and some correlation between disease severity and photosynthetic capacity of tomato plants.

Key words: photosynthesis, cover crops, Fusarium oxysporum, tomato.
