Abstract

In this work are presented preliminary results of a nursery growth of different clonal populations of Artemisia arborescens L. in man-made substrata. The final goal of this study is to evaluate the potential use of these substrata in rehabilitation of areas polluted by heavy metals due to the past mining activity. Man-made substrata were created by mixing several raw materials. These materials were characterized for mineralogical composition and textural classes. Different substrata were studied for physical-chemical parameters. Evaluation of substrata functionality, was carried out measuring growth differences (height) of different Artemisia specimens. On the basis of empirical growth curves, were calculated growth theorical curves. The comparison of these curves allowed to define the influence of the genetic variable on the growth of different clonal populations planted in the same substrata and the influence of different substrata on the same clonal population. Differences between coltural conditions, were highlighted by measuring the content of A, B and total chlorophyll too
