  • Title: [Spontaneous and induced sterility by ethyl methanesulfonate (EMS) in Nigella damascena L].
    Author: Gilot-Delhalle J.
    Journal: Cellule; 1976; 71(2):217-28. PubMed ID: 186186.
    Abstract:
    EMS-induced sterility could be very partially due to chromosomal aberrations appearing during male and female meiosis or even to mechanical abnormalities of the double fertilization. The sterility could be also related to diplontic origin (lethal factors or small deficiencies appearing in homozygous state on account of self-pollinization). Owing to our histological and genetical data, a female gametophytic origin could be mainly ascribed to EMS induced sterility. It could arise from a damage of the feeding function of the nucellus.
