Abstract

Trials on the introduction and cultivation of Arnica montana L. (Asteraceae) in Bulgaria.

Abstract

The aim of the present study was to consider the possibilities for introduction and sustainable cultivation of Arnica montana in Bulgaria. The research was conducted on two experimental fields in different floristic regions of the country at 1 400-1 500 m altitude. The experiment was conducted with seeds of two origins: a natural population from the Carpathians (Ukraine) and the variety "Arbo" (Germany). Comparison between in vivo and in vitro propagated plants under field conditions was carried out. During four vegetation seasons the growth and development of the plants were monitored and the survival rate was evaluated. There were no significant morphological differences between the plants of both studied origins while in vivo and in vitro propagated plants had high parameters variation. The obtained results proved the possibility of sustainable cultivation of A. montana in the high-mountain regions of Bulgaria.
