| Abstract:
The species is a very popularly used plant as woundwort. Leaves, top flowers and rhizomes are used. The objective of this work is a contribution to the germination study, photoblastism and more adequate temperature for reproduction of the species. The best temperature for the germination was found to be 20°C and no seeds germinated under continuous darkness, within 14 days; therefore, the seeds are positive photoblastics. The seed germination percentage was low, in relation to the mass of the achene produced, varying from 8,2 to 20,0%. The alternated temperatures of 20° and 30°C did not influence the seed germination and the average of the weight of 100 seeds was 0,026 1 g. | |
