Abstract: | 3H-thymidine incorporation and DNA-polymerase activity during early hours of wheat embryo germination at two viability levels
have been studied. The patterns of two biosynthetic activities, as well as the dependence of DNA synthesis on protein synthesis,
indicated the presence of a delay in the early phase of imbibition of the aged embryos with respect to viable germs. |
