Autoradiography with Ca45 has been used to obtain information about the relation between calcium and chromosomes. Labelled pollen from the Easter lily, Lilium longiflorum, was allowed to develop into pollen tubes between 5 and 6 cm. long in the style

THE lack of calcium in Tradescantia microspores and in barley seeds has been demonstrated to increase the frequency of X-ray-induced chromosome aberrations above similarly irradiated material grown with optimal calcium1,2. Mechanisms by which the lac

MANY chemical and physical treatments have been used for producing non-heritable changes in development. When such changes resemble known mutants, they are called phenocopies. A variety of phenocopies has been induced by metals or metal-inhibiting co
