Abstract

NEDKOV, N., 2007. Research on the Effect of Pre-sowing Treatment on Seed Germination of Hypericum perforatum L. Bulg. J. Agric. Sci., 13: 31-37

Trials were carried out for improvement of seed germination of St. John’s Wort (Hypericum perforatum L.) based on studies of main sowing properties after treatments as follows: soaking, soaking and heating and combined seed stratification. Recommendations were made for the best pre-sowing seed treatment, 24 h soaking in cool water bath at room temperature and 7-day stratification at 0.5 °C.
