The occurrence of flavanols in the nuclei of several tree species (Feucht et al. 2004) is highly debated. Microscopic studies using DMACA staining revealed flavanols in shoot tip cells of Tsuga Canadensis during the early anaphase and in prophase nuclei. Chromosomes could be stained for flavanols and artefacts could be excluded to the greatest possible extent, but the function of flavanols at this site remains obscure. ¶àл£¡ |
