Abstract

Labelling of the nuclear cycle with ³H-thymidine and the determination of the minimum mitotic cycle by means of colchicine have shown that a 0,4% v/v concentration of ethyl alcohol given to root tips of Allium cepa for two hours induced a mitotic delay of 13 hrs. The S phase is delayed 6 hrs, and the delay of G, is calculated to be about 7 hrs; G₂ and prophase are not aifected by the treatment.
