Tradescantia Commelinaceae

Three distinct chemotypes were observed. Taxa from each of the three areas noted above exhibited unique combinations of the compounds and compound types, although there was a degree of variation within most groups, as one might expect. The North American chemotype was characterized by very high frequency of the sulfated cinnamic-acid derivatives, a frequency of flavonol derivatives of

Several species in the family Commelinaceae, of which Tradescantia is a member, have features particularly well suited for certain radiobiological studies. Effects produced by ionizing radiations which are easily studied include (1) chromosome aberrations in microspores, root tips, ovaries, and stamen hairs (2) somatic mutations in petals and stamen hairs in clones heterozygous for flower color (3) pollen abortion (4) loss of reproductive integrity in stamen hairs and (5) whole plant or seedling death. The stamen hairs of Tradescantia clone 02 have also proved...
