MORPHOLOGICAL AND CYTOLOGICAL EFFECTS OF RADIOACTIVE PHOSPHORUS AND RADIOACTIVE SULPHUR IN SOME CEREALS AND LEGUMES

Published on

A study of the cytological and immediate morphological effects of treatment with
radioactive phosphorus (P3
2 ) and radioactive sulphur (S35) was undertaken to
evaluate the cytological effects of low doses of beta radiation and the claims of some
workers that low radiation levels stimulate crop growth. In addition, it was hoped
that such a study will provide useful data concerning the determination of dosage
thresholds to be adopted in large scale experiments for inducing mutations in these
plants. The importance of mutation breeding in solving specific problems facing the
plant breeder is well known; Gustafsson and Tedin (1954) and Gustafsson (1957)
have summarised the role of radiation in plant breeding.
