GROWING TECHNIQUES OF PERFORATE ST. JOHN’S WORT(HYPERICUM PERFORATUM L.)FOR PHOTOCULTURE

This paper discusses the productivity evaluation results (shoot length, shoot number, leaf size, and yields) of hy-droponically grown perforate St. John’s wort (Hypericum perforatum L.). Hydroponic technique enables year-round growing this medicinal plant preserving natural population in Khanty-Mansiysk Autonomous District -Yugra; wortis listed District’s Red Book as species that should be closely monitored its habitat. A vertical ebb-and-flow hydroponic unit was used for growing. The research target Optimist variety wort. Generally ac-cepted methods were applied. Phytopathological plantation re-vealed low level infestation with fusarium disease (less than 5%). experiment showed plants reached best values all growth indices when under white lights luminous flux 8000 lm, color temperature 4000 K, РРF 165 μmol s m2.
