Comparison of disease development on Solanum lycopersicum and Solanum lycopersicoides. (A) Lesion development on S. lycopersicum and S. lycopersicoides was observed at 0, 24, 48, and 72 hours after inoculation (hai) with B. cinerea. White bars represent 10 mm. (B) Lesion diameter and (C) ergosterol content were measured to quantify disease development and fungal growth, respectively, on S. lycopersicoides (Blue) and S. lycopersicum (Red). (B) For lesion diameter, values represent the mean diameter of 32 individual lesions, and error bars indicate standard error. (C) For ergosterol content, values represent the mean of 3 separate leaves, and error bars indicate standard error. Both fungal growth and lesion diameter increased in S. lycopersicum compared to S. lycopersicoides at 72 h after inoculation.
