To the purpose of the action of some drugs over the seeds’ germination

Abstract

The AA. studied the action of substances already known as bactericide or bacteriostatic over germination of some kinds of seeds: lettuce (Lactuca sativa L.); cabage (Brassica oleraceae capitata form); radish (Raphanus sativus L.); green kale (Brassica oleraceae acephalous form). They found that in concentrations such as 1:100, 1:1,000, 1:10,000 and 1:100,00, the formaldehyde and the mercuric cloride have inhibited action over the seeds mentioned before. The drugs act over the embryo determining the breeding incapacity; regarding the calcium propionate and nipagin (etilic ester of para-hidroxibenzoic acid) the inhibited action is a consequence of the presence of such substances. The seeds after 48 hours of contact with these agents were washed in water and showed themselves capables of breeding.
