ABSTRACT

There was estimated a susceptibility of grains of the naked oat cultivars: Akt, Cacko, Polar and the line STH 4659 collected at grain moisture content from 22.9 to 10.9% to mechanical damage caused by threshing at two cylinder speeds of the threshing device: 1.6 and 2.4 m·s^-1. The control samples were made up of hand-threshed grains. Macrodamage to the embryo, damage to the endosperm and to parts of grains were distinguished. The grain endosperm (7%) and the embryo (about 5%) were most strongly exposed to the direct operation of thresher elements. Damage occurring on the embryo, in the endosperm and, at the same time, on the embryo and endosperm were distinguished in the study of microdamage, and their share ranged from 10 to 40%. Highly significant relationship between the sum of microdamage classes and the number of damaged grains (r = 0.47), total damage area (r = 0.52) and the share of damage area (r = 0.55) shows the applicability of the computer image analysis to evaluate the mechanical damage of oat grains.

Key words: computer image analysis, naked oat, mechanical damage.
