Änderungen im gehalt an phenolischen substanzen in regenerierenden zellen des lebermooses Riella helicophylla

Abstract

Summary A recently developed microanalytical method made it feasible to determine the phenolic content in small regenerating fragments during the first 72 hours of regeneration. The regenerating fragments elevate their content with steadyness and very quickly, reaching a level of about 300% at 72 hours after fragment isolation. This effect is specifically caused by the regenerating cells of a fragment. The non-regenerating fragment cells accumulate less phenolics. It is estimated that regenerating cells reach a phenolic level similar to that in meristematic Riella cells just at a time when they reinitiate DNA-synthesis.
