Application of a colour image analysis of kernels in evaluation of the infection of triticale grown in different cultivation systems

摘要

The usefulness of the computer analysis of the kernel colour images was evaluated with two triticale cultivars -- winter Ugo and spring Gabo, grown in 3 cultivation systems (ecological, integrated and conventional) following inoculation of spikes with Fusarium sp. pathogens. Image analyses were carried out using the MultiScan~(R) 4.01, set up and calculations were made using of MS Excel. With the applied technique it was possible to distinguish differences between inoculated and control (non-inoculated) grains and to determine the influence of the cultivation system on seed coat colour. The method described is very useful for a rapid evaluation of kernel colonization with Fusarium sp. pathogens, and can significantly support control of seed quality and grain quality for food and feed purposes.
