摘　　要：收集并整理2014~2016年从黄埔和南沙口岸进境美国高粱中截获的杂草种子,对截获频次进行统计,并对截获频次较高的9种检疫性杂草、14种非检疫性杂草进行萌发试验,结果表明,供试杂草种子几乎均能萌发,且萌发率较高,如长芒苋和裂叶牵牛萌发率达58%以上、糙果苋19.17%、假高粱和豚草的萌发率也达到7.50%和5.00%。因此要重视美国高粱中携带的杂草种子检疫以及杂草监测工作,防止这些杂草种子的定殖传播。Weed seeds intercepted from imported American sorghum from 2014 to October 2016 in Huangpu and Nansha port were collected and seed germination experiment by using 9 quarantine weeds and 14 non-quarantine weeds with high intercepted frequency showed that all most of the intercepted weed seeds can germinate with high germination rate,such as Amaranthus palmeri and Pharbitis nil were more than 58%,Amaranthus tuberculatus were 19.17%,Sorghum halepense and Ambrosia artemisiifolia were7.50% and 5.00%. So we should pay attention to the weed quarantine and monitoring of imported American sorghum and prevent the weed spreading.
