RESEARCH ON THE EFFECT OF TREATMENT WITH MUTAGEN CHEMICAL AGENTS OVER THE FORMATION PROCESS OF RED CLOVER NEOPLANTS.

The paper follows the study of the influence of DES and DMS over the formation process of red clover neoplants. There were made observations and biometric measurements concerning the biological material amenable to the treatment with mutagen agents in all the phases of developing in vitro, from the sampling of plantules under phenotypic aspect. DES manifest an mutagenic action over both types, according with the administered concentration. DES₁ type has a positive influence over this evolution phase of meristems, in the case of both types DES increases the neoformation capacity of neoplants from the meristem, at both types. In this phase DMS didn't stimulated the regeneration capacity of neoplants from the meristems indifferent of the applied dose, the differences being meaningful negative up to the witness, for both types. It was also found that the inhibitor effect of DMS₁ and DMS₂ over the rate of rootedness of resulted plantules through in vitro culture, effect that is added with the increasing of the agent mutagen concentration of this type.
