Abstract It is known that carbonhydrates are precursors of all bioactive substances we tried in thes paper work to do some investigation on these substances in the environmental area of Iasi. To observe the influence of some chemical mutagens substances on carbohydrates biosynthesis we conducted investigations on plant material (leaves) taken from the Calendula officinalis L species. We used this assay to examine the effects of the herbicide 2,4- dichlorophenoxyacetic acid (2,4-D), etidium br...

The most important argument of this experiment was to demonstrate an increased content of active principles under the influence of some substances (considered in the literature as mutagene), when used in low concentration, do not affect the environment. The purpose of this study was the selection of some treatment variants, which, during the experimentations show the same biosynthetic potential, stabilized or increased. The substances used in the experiment were ethidium bromide at the concentra...
