Abstract: | The integrity of ribosomal RNA (the percentage of complete, un-nicked molecules) in seeds was studied by electrophoresis under
denaturing conditions. Two batches of carrot seed, harvested at different stages of maturity, and four batches ofNicotiana seed stored for various times were used. Within each species, there was a correlation between the integrity of the rRNA of
the dry seed and the rate of germination of that seed. In carrot seed, there was extensive degradation of existing rRNA in
both the embryo and endosperm during the first two days of imbibition. |
