Given the fact that many of the seeds of medicinal and aromatic plants spring up very slowly and unevenly, at A.R.D.S. Secuieni were experienced in laboratory conditions, speeding up and improving germination in the species Hypericum perforatum L., Echinacea purpurea L. (Moench.) and Salvia officinalis L. Due to the research made at A.R.D.S. Secuieni was found that the optimum temperature for germination in the laboratory conditions to the seeds of the three species is 20 – 220C. The organic treatments made at seed led to shortening the period from when the seeds were put to germinate and until
they began to germinate, but also of the period from sowing to emergence. The most effective variant was the one where the seeds were soaked 48 hours and were kept in refrigerator for 12 hours at 40ºC, the period from sowing to emergence at the Hypericum perforatum L. was reduced to 9 days versus 48 days (in control variant - untreated). At Echinacea purpurea (L) Moench. still to this variant the period from sowing to emergence was reduced to 8 days compared to 45 days as it was in the control variant – untreated, and at Salvia officinalis L. this period was of 6 days.
