The article brings the results of three-year studies of the
influence of the periods of sowing on productivity of
new varieties and lines of winter barley
The article presents data on the morphological and biological characteristics of Agrodeum varieties, the results of the competitive test were shown, as well as the adaptability of varieties to different conditions of cultivation and the main indicators of quality of new grain varieties
In cell biology, actinomycin D is shown to have the ability to inhibit transcription. Actinomycin D does this by binding DNA at the transcription initiation complex and preventing elongation of RNA chain by RNA polymerase. When soaking the seeds in a solution of actinomycin D, antibiotic blocks RNA synthesis and seed germination occurs at the expense of long-living RNA, available in the mature seed. In the article we present experimental data indicating that as storage seeds of winter barley are changing the action actinomycin D on the growth of coleoptiles. It is shown that actinomycin D at a concentration of 40 µg/ml in October reduced the growth, in December it was not authentically, and in February it was paradoxical amplified growing coleoptiles. We suggest the part of the actinomycin D fastened with growth inhibitor coleoptiles, whose structure changes during seed storage and increase the affinity of actinomicyn D to the inhibitors. At a concentration of 60 µg/ml actinomycin D effectively reduced of the coleoptiles growth. Suppression of seedlings roots growth was proportional to the concentration of the actinomycin D and exposure time
Results of three-years of examining the collection material of winter barley of different ecological-geographic origin are brought in this article. We have also allocated sources of high grain productivity, winter hardiness and precocity for further use in breeding programs
We have described the theoretical assumptions and methodological solutions in the present review. They are innovative possibilities in the development of laboratory methods for assessing biological features of grain during the selection process
