Abstract

Radiographic technique developed at this Station for the determination of internal or hidden insect infestation in stored grain has proved to be useful for the detection of other physical anomalies in grains. Practical applications of this sort include the detection of cracked or broken kernels in rough rice (paddy) prior to milling as well as the extent of internal fracturing of certain grains such as maize due to uneven stresses arising from severe drying conditions. This communication deals with a condition of internal fissuring occurring in wheat due to weathering of the ripened grain in the field.
