Abstract:
Amsonia tabernaemontana is a perennial species belonging to the flora of North America. It adapts well to temperate and cold climates. The plant is interesting because its leaves contain rutine in a concentration of about 4 – 5 %, and it could be grown extensively in marginal areas.

The seeds of A. tabernaemontana are characterized by slow and uneven germination. The present study aimed at investigating the best conditions for a good and uniform germination. Seeds of two populations from two areas around Piacenza were bred in dish and soil with three types of treatment (water + cold; GA3 1 mM; GA3 10 mM), plus one untreated test.

The treatment with the highest concentration of gibberellin proved to be the one which gave the best results for germination percentage (G %) and average germination time (AGT), both in new and one-year-old seeds.

The study also shows the preliminary results on the rutine content of several samples of A. tabernaemontana grown in our environmental conditions.
