Atypical growth, abonormal mitosis and polyploidy induced by ethyl-mercury-chloride

Journal Article:

Abstract

Experiments were performed to study the effect of ethyl mercury chloride upon the atypical growths of plants. Seeds of peas, flax, rye, and wheat were treated with 2% ethyl mercury chloride. The fungicide suppressed the development of the seedlings. Cytological studies revealed that the fungicide had also significantly affected the procedure of mitosis in most of the treated seedlings. The chromosomes did not become arranged into a proper equatorial plate when the nucleus membrane and the nucleolei disappeared, but occupied a position similar to that which they had during the prophase. The chromosomes split, then the centromeres divided so that from each one chromosome, two chromosomes originated, situated side by side without polar separation, chiefly due to the absence of normal achromatic figures. Thus, chromosome division without cell division takes place.
