Abstract : The report gives the results of an initial series of experiments in which cells from various organisms were vibrated at frequencies of 40 and 70 cps with 10 and 20 G's. Microspores of Tradescantia paludosa (Clone 3 of Sax), conidia of Neurospora crassa (L-prolineless clock-mutant, FGSC No. 491a), Neurospora crassa (N.R.C. No. 865A), and ova, larvae, and pupae of Drosophila melanogaster (wild type) were studied for chromosomal rearrangements. No influence was found of these vibration frequencies and accelerations on N. crassa, T. paludosa, and the p sub 1 generation of D. melanogaster, but there was observed the presence of body color and wing shape mutants among the F sub 1 generation of D. melanogaster. In future work these organisms will be subjected to other frequencies and displacements of vibration. (Author)
