Abstract
The frequency of mitomycin C induced somatic crossing over in variety L65-1237 of Glycine max is shown to be dependent upon the (physiological) age of the seed during post germination period. Effect of mitomycin C during the first four hr of germination is significantly lower than during later periods. This increase in the frequency of somatic crossing over is observed up to about 20–24 hr and is then followed by a decrease. These changes did not appear to be related to the onset and pattern of synthesis of DNA or/and proteins in the embryonic tissues. However, mitomycin C is effective even when no DNA synthesis is going on.Keywords
