H?rtbarkeit und Auswahl von St?hlenmutation in this organism after treatments with several mutagens has been investigated. UV rays, X-rays, Diepoxybutane, 4-nitroquinoline-N-oxide and 8-methoxypsoralen+ UV-A were almost completely ineffective in raising the mutation frequencies over the spontaneous one. UV rays were tested in a varie
