Abstract
Abstract Two sweet corn hybrids, ‘Bonanza’ and ‘Monarch Advance’ ( Zea mays L.) were evaluated for their relative susceptibility to ambient photochemical air pollutants (principally ozone) in outdoor chambers at Riverside, Calif. The plants were exposed daily to ambient or activated carbon filtered air, from seedling emergence to fresh market harvest. Plant height, tiller number and length, and air‐dry weight of stalks were reduced by pollutants in both cultivars. However, the number and fresh weight of marketable primary ears and the number of fully developed kernels were much more severely reduced in ‘Monarch Advance.’ Some acute leaf tissue collapse and premature yellowing and senescence of leaves were prominent in ‘Monarch Advance’ but nearly absent in ‘Bonanza.’ These foliar symptoms agree with previous data on the behavior of the two cultivars in the field.
