RESEARCH ON THE EFFECTS OF RADIATION ON "NICOTIANA." III. ASPECTS OF THE RADIORESISTANCE OF THE GENUS NICOTIANA (in Italian)

OSTI ID:4843058
The presence of species at different levels of ploidy in the genus Nicotiana was utilized to study correlations between polyploidy and radioresistance. Seeds were irradiated with x rays (doses from 2,000 to 64,000 r) or with fast neutrons (doses from 110 to 6,250 rep). Germination chromosomal aberrations and LD/sub 50/ at the 4 to 6 leave stage were the events considered. The experiment showed that the diploids are more radiosensitive thnn the polyploids, among them N. rustica is more resistant than N. tabacum Among the cultivators of this species V. bright, as pre viously observed, confirms its higher radiosensitivity.
