Differential Susceptibility of Sweet Corn Hybrids to Field Injury by Air Pollution1

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.

Protecting Horticultural Plants from Atmospheric Pollutants: A Review1

“…'Great Lakes' and 'Black-seeded Simpson' lettuce and 'Icicle' lettuce were the least sensitive (56). In field plantings, sweet corn hybrids were reported to show differential injury resulting from oxidant pollutants (11).…”
