Blooming of romanas rose (Rosa rugosa Thunb.) cultivated on ash dumps reclaimed with various techniques

This article presents the results of a study on the cultivation of romanas rose on ash, carried out between 2004 and 2006. The experiment involved two different substrata and five different fertile covers. The control group comprised of roses growing on native grounds and raw ash rock. The study measured the viability of the plants, number of flowers and fruit borne from these flowers. This study showed that the techniques of reclamation applied in this study significantly influenced the examined characteristics of romanas rose. Fertile covers increased the growth and blooming, however the most desirable results were obtained when the cover consisted mostly of mineral matter
