        Physical and Physiological Dormancy in Black Henbane (Hyoscyamus niger L.) Seeds

        C¸lrak, Cu¨neyt,Kevserog˘lu, Kudret,Sagˇlam, Birsen 한국식물학회 2004 Journal of Plant Biology Vol.47 No.4

        Aim of this study was to investigate the nature of dormancy in black henbane (Hyoscyamus niger) seeds which have low germination rate under normal laboratory conditions. To do this, before placing the seeds in Petri dishes, they were soaked in 5, 10 and 15 ㎎/L GA; 1, 2 and 3% H₂SO₄,15 ㎎/L GA + 1% H₂SO₄, 0.01 M KNO₃ solutions, tap water, 40, 50 and 60°C hot water for 30 min. The study was performed under both continuous illumination and darkness in growth chambers to evaluate the effect of light on germination rate. The results showed that H₂SO₄ and GA treatments were the most important factors affecting seed germination and their germination enhancing effects were more evident in darkness. The results also suggested that black henbane seeds exhibit double dormancy involving a hard seed coat and a partially dormant embryo and have a partial dark requirement to germinate.
