Frost/heat stress damage (FRHTS)

Description

Frost/heat stress is a subjective grading factor.

The kernel has a wrinkled to blistered appearance depending upon the stage of kernel development, the moisture content and the degree and duration of exposure to the extreme weather.

Frost/heat stress is reported in our grading system without differentiating the factor, since they are visually indistinguishable and have the same detrimental effects on quality.
