Abstract
The RNase activity, the acid-soluble, soluble N, RNA, DNA and protein contents have been followed in the shoot, the roots, the scutellum and the endosperm of germinating barley. A correlation between RNase activity and RNA content has been observed in the growing organs. Results suggest the existence of a transIocation of macromolecules associated with synthetic processes. Three phases can be recognized during the germination of barley seeds grown on water in the absence of photosynthesis :
1) a three days' period in which transIocation predominates ;
2) another three days' period in which synthesis takes over ; and
3) a long etiolation period associated with catabolic processes.
On the basis of our results the possible role of RNase as a morphogenetic
substance is suggested.
