以韓國之真珠草(Shatterstone，Phyllanthus urinaria L.)種子為材料，進行種子萌芽試驗。未處理直播之萌芽率介於35-50%之間；種子採照光與否、漂水及層積三個因子之複因子處理，三種處理均可明顯影響萌芽率；播種於黑暗中之萌芽率較光照下者為佳；漂水處理對萌芽率略有抑制的趨勢，層積前漂水之萌芽率低於不漂水者，但未達5%之顯著差異水準，而層積後漂水則明顯降低萌芽率；層積處理可提高萌芽率，其中以層積2週之處理促進效果最佳，層積4週者促進效果反而下降。建議真珠草較佳的種子處理為：種子先水選消毒後層積於5℃下兩週，並播於黑暗中或播種後覆土。

The study was to investigate the germination rate of Shatterstone(Phyllanthus urinaria L.) seeds, imported from Korea, on different treatments. The germination rate of untreated seeds was between 35% and 50%. Light, rinse and stratification affect significantly the germination rate of Shatterstone. Seeding in dark prove the germation rate; Seed rinse would restrain it; Stratification significantly increase germination rate of Shatterstone. The better stragification duration is 2 weeks, 4 weeks would decrease the improvement, instead. Suggest seed treatments of Shatterstone is, stratification for 2 weeks after water-selected and disinfection, sow in dark or mantle with soil.
