- The seeds of seven A. Montana and four R. rosea wild accessions, collected in different natural sites of Trentino (Italy), were used to carry out the trials. As regards arnica the seed germination varied from 34 to 91%, the mean germination time (M.G.T.) from 7.9 to 8.9 days and the thousand seed weight (T.S.W.) from 0.88 to 1.56 g. In the case of roseroot (seeds treated with 100 mg L-1 of GA3 to overcome the dormancy) the germination capacity varied from 85 to 96% and the T.S.W. from 0.11 to 0.16 g, while the M.G.T. was 9.7 days on average.
