Abstract
Experiments were conducted to investigate possible protein changes in mature corn kernels caused by the corn earworm, Heliothis zea (Boddie). Our objectives were to determine protein content of mature corn kernels sampled from corn ears infested by the corn earworm at various times after silking, and to compare these levels with the protein content of corn kernels sampled from ears with simulated corn earworm damage and from those that were not infested. Protein content of the corn kernels was estimated by using near-infrared reflectance. Protein content of corn kernels from ears subjected to corn earworm damage early in kernel development, 0–3 d, was significantly higher than that of undamaged ears or ears with later earworm damage. The protein content of kernels from ears with kernel damage, either earworm or mechanical, was higher than that of corn with no damage or husk damage only. Finally, protein content of corn kernels was higher in corn grown in 1982 than from corn grown in 1981.
