Preliminary results for Monarda bradburiana germination after 30 days

Two of the three species in Group A have completed their first 30 days in the growth chamber and have been moved to the greenhouse.

Group A species received no moist-cold stratification treatment. They were placed in the growth chamber at 24C immediately after imbibement. Preliminary results for this treatment of the three species is listed on the table below. Although the percent germination for Vernonia lettermannii is very low, it is higher than anticipated considering the 2% viability determined by the preliminary TZ test.

Monarda bradburiana had significantly higher germination rates than the other two species, which makes it a more likely candidate for seed mix production. Stratification treatments are already proving to improve germination rates for this species as well, with germination of 46% after 3 days in the growth chamber.
