| Abstract | Goal. To find out the influence of initial germination of winter wheat seeds in sealed and unsealed containers in chamber and storage conditions depending on their moisture content on their quality during long-term storage. Methods. The research was conducted at the experimental farm of the Institute of Plant Physiology and Genetics with the winter soft wheat variety Bogdana selected by Institute of Plant Physiology and Genetics and the winter durum wheat variety Aisberg Odesskyi selected by the Institute of Breeding and Genetics during 2016–2021. The experimental scheme provided for the storage of seeds in sealed and unsealed containers in a storage and climate chamber with a humidity of 7,0–8,0 % and 10,9–13,0 %, which had an initial germination rate regulated by the standard of 92–95 % and a germination rate of less than 85–90 %. Results. It was found that seeds of Bogdana and Iceberg Odessansky varieties with an initial germination rate of 95 % were best stored in both sealed and unsealed containers in the storage and climatic containers. With a seed moisture content of 12.4 %, storage in leaky containers in the storage facility resulted in a complete loss of quality energy by 61 %, germination by 69 % and growth force by 66 %. Storage conditions and seed quality of both varieties before storage also affected the change in air-dry weight of sprouts and roots, which significantly decreased under all storage methods, except for storage in a sealed container and seed moisture content of 7.9 %. During storage of seeds with an initial germination rate of 95 % and moisture content of 7.9 % in sealed and unsealed containers, both in a climate chamber and in an air-dry storage facility, the dry weight of sprouts and roots did not decrease, but rather tended to increase. With an increase in seed moisture content to 11.5 %, these indicators decreased, especially in seeds with lower germination. Conclusions. Seeds with 95 % germination were best stored in sealed containers with a moisture content of 7.9 %. When storing seeds with the minimum permissible germination according to DSTU 92%, their quality significantly decreased both when stored in sealed and unsealed containers in a climate chamber and storage. A decrease in seed germination from 90 % to 85 % before storage, during long-term storage, the quality of the seeds lost regardless of storage conditions and, especially, at a seed moisture content of 12.4 %. | ||
