Abstract
Twelve cultivars of tomato were exposed to 40 pphm ozone for 1.5 hr in separate morning and afternoon exposures to determine differences in cultivar sensitivity. Nearly all of the cultivars exposed in the afternoon developed more injury than similar cultivars exposed in the morning. Cultivar ranking, however, was the same in morning and afternoon exposures. ‘Roma VF’ and ‘Red Cherry’ were among the most sensitive cultivars tested and ‘Heinz 1439’ and ‘VF 145B’ were the least sensitive of the 12 tomato cultivars tested.Keywords
