X-ray of seeds in breeding of berry crops

Abstract

The article is devoted to the use of x-rays to determine the quality of hybrid seeds of berry crops such as raspberries, blackberries, strawberries, strawberry, blueberries, red currants and gooseberries. All examinations were performed with the use of x-ray equipment PRB-02. For detailed examination of small seeds, an x-ray microscope RM-01 was used. It was revealed that even visually full-fledged seeds of berry crops have internal hidden defects, such as rotting of the seed, detachment of the shell from the cotyledons and failure. Microfocus radiography of the seeds of gooseberries and currants showed that the shells of these seeds reacted poorly to x-ray irradiation in the sense that the outlines of the cotyledons and the embryo had no clearly defined boundaries. The method of microfocus radiography can be successfully applied in the selection of berry crops to determine the quality characteristics of seeds and their viability.
