S. Gunasekaran et K. Muthukumarappan, BREAKAGE SUSCEPTIBILITY OF CORN OF DIFFERENT STRESS-CRACK CATEGORIES, Transactions of the ASAE, 36(5), 1993, pp. 1445-1446
Breakage susceptibility (BS) of different kernel stress-crack categori
es (single, double, and multiple) were tested for two varieties of cor
n using the Wisconsin and Stein breakage testers. The single category
had the lowest BS, followed by those of the double and multiple catego
ries the relative breakage susceptibility values calculated based on t
he BS of the single category indicates that the increase in the BS due
to increase in stress-crack level is in the range of 5 to 43%, depend
ing on the corn type and BS test device used. The whole sample BS is u
sually lower than that of the single category, but the actual value de
pends more on the proportion of kernels in different stress-crack cate
gories than on the total stress-cracked kernels in the sample.
