| Abstract: | The studies on seed germination of bearded iris that influenced by light and seed coat were carried out. The results indicated that the biggest expanding rate was 138% in 192 h with 77.35g of 1000-grains weight. The dark condition at normal temperature （average 20 ℃ ） could benefit seed germination, which reach 54.54%. |
