Abstract Marked differential injury by air pollution to a group of sweet corn hybrids in 2 experimental field plantings in the Los Angeles Basin occurred in 1969. At Riverside, leaf damage ranged from nearly zero in 11 hybrids to slight to severe in 23 others. Damage was clearly related to cultivar and was associated with periods of high oxidant levels and high maximum temperatures. There was only a slight relationship between the market maturity date of a cultivar and its degree of damage.
