Ineffectivity of metallic salts in induction of somatic crossing-over and mutations in Glycine max L. (Merrill)

Abstract

Seeds of variety L65-1237 of Glycine max (soy-bean) were soaked up to 28 h in aqueous solutions of AlK(NO 3 ) 2 , CuSO 4 and FeSO 4 and their different mixtures, in concentrations ranging from 1–50 p.p.m. Analysis of the two simple leaves and the first compound leaf (for chlorophyll development) in the heterozygous ( Y 11 y 11 ) and homozygous ( y 11 y 11 ) plants indicated that the chemicals tested do not increase the frequency of mutations or somatic crossing-over a studied by spot counts on the leaves.
