OSTI ID:7330187
Inflorescences of several clones of Tradescantia heterozygous for flower color have been treated with ionizing radiation and with the gaseous form of several known or suspected chemical mutagens. Pink somatic mutations were subsequently scored in the stamen hair cells of mature flowers and dose-/exposure-response curves constructed. Results indicate clearly that there is no evidence for a threshold for mutation response following x or neutron irradiation. Results so far obtained for gaseous chemical mutagens are less clear, but also suggest that there is no threshold for mutation response.
