Overview

Experiments in small plots were performed to cultivate Hypericum perforatum L. var. angustifoliumDC on light soil and at a sunny location in Bratislava. In the 1 st year of vegetation the herb was notharvested. Harvests were made in the 2 nd and 3 rd years of vegetation and later plants died. In thecourse of the vegetation year it was possible to carry out three harvests on the rule. The 1 st one wasmade just prior to blooming or at the stage of the onset of blooming, and only the blooming top partswere collected. The yield of the dry tops varied in dependence on the vegetation year, conditions ofthe location, age of the plants, and the date of the 1 st harvest. From the two-years old plants,a whole-year yield of 8.12–14.87 kg.10 m –2 of dry tops and from the three-years old plants, 8 kg. 10 m –2 , was obtained. The content of hypericin varied from 0.06 to 0.13 %, and 60% ethanolextracted 21.7–27,9 % of substances.
