Abstract

|
This study was carried out to examine seed characteristics of Artemisia capillaris and the effects of different temperature and light on its seed germination, and of sowing date on its growth and yield. A seed of A. capillaris, 0.79 mm in length diameter, 0.39 mm in width diameter and 0.054 g in thousand-kernel weight, was extremely small, vertical pinstripes in the surface of seed, and long oval of dark brown in shape, and its maturity occurred September to October. A germination rate was superior at light conditions and 20 to 25^{circ}C in temperature. Although its germination became shorter as the higher temperature. Its emergence rate was the highest in sowing at March 30. But the growth and yield potential was the best when sowed at March 20. The earlier the sowing date, the higher yield.
