The investigation covers the causes of changes in the biological activity of embryos during development and maturation as well as germination of wheat and triticale caryopses. It was shown that transcriptional activity of embryos changes in the course of grain development in the rythmical way and the main regulating factor seems to be abscisic acid. Big changes both of quantity and quality were also observed in ribosomal proteins of embryos in the course of grain development. The susceptibility of embryos to abscisic acid decreased with the development and maturation of caryopses, which is another evidence that the acid takes an active part in the induction of dormancy of caryopses but not in the process of maintaining the state of dormancy.
