| 糙叶丰花草为海南本地常见的草本植物，适宜在热带果园作为草种生草栽培。为提高对糙叶丰
花草种子的认识，为引种栽培提供技术支撑，研究了其种子的特性和发芽规律。结果表明：糙叶丰花草种子
千粒重2.28 g，含水率22.93%，无硬实现象；种子存在初生休眠现象，休眠期长短不一；破除种子休眠的适
宜方法是采用浓度150～300 mg/L 赤霉素浸种24 h，而采用热水浸种的效果不明显；种子发芽最适宜的温度
为30～35℃，最佳土壤相对含水量为30%～50%，播种深度在6 cm 以上时出苗率较高。因此，建议在播种
糙叶丰花草前，预先采用浓度150～300 mg/L 赤霉素浸种24 h 处理，播种时避开低温季节，深度以6 cm 以
上为宜，同时避免浇灌过量，有利于种子萌芽出苗。 |

| Borreria articularis（ Linn.f.） F N Williams is a common herbaceous plant used widely in tropical
orchard china in Hainan Province，The paper studied the characteristics of germination of B. articularis（ L.f.） F.
N. Williams seed. Results indicated that：the 1000-seed weight was 2.28 g，the moisture content of the seed was
22.93%，and had no hard to cook phenomenon. The seed had primary dormancy，the dormant period varied. The best
method of sreak seed dormancy was that seeds treated with 150-300 mg/L GA3 for 24 hours，and the effect of soaking
seeds with hot water was not significant. The optimum temperiture for the seed sprouting was 30-35℃，the optimum
soil water content was 30%-50%，and the seedling rate increased with increase sowing depth up to 6 centimeters.
Therefor，it is recommended that soaded seeds priviously with 150-300 mg/L GA3 for 24 hours before sowing，
avioded low temperiture and excessive watering during sowing，it is also advisable to sowed seeds at the depth 6
centimeters and more，which was beneficial to seedling. |
