Cyto genetics of aquatic ornamentals part 4 effects of gamma irradiation on nymphaea rubra



Cytologia 42(2): 297-304



ISSN/ISBN: 0011-4545

Irradiation of N. rubra rhizomes by 2, 3 and 4 krad of .gamma.-rays induced morphological and cytological changes. The 5 krad and higher doses were lethal. Morphological changes concerning floral and vegetative parts of irradiated plants mostly belonged to the primary effects of radiation and were unstable. Change from toothed to entire leaf margin, numerical alterations in petals and stamens, induction of narrower or twisted petals with obtuse tips and changes in the contour of androecium and intensity of petal color were stable. Cytological alterations included formation of interchange multiples, fall in chiasma frequency and aberrations of chromosomes in the irradiated plants. Pollen fertility decreased after irradiation, and rhizomes treated with 3 and 4 krad became completely sterile.
