| Abstract: | The present paper deals with the developmental zero and effective accumulative temperatures of the worst weeds, Paspalum thunbergii Kunth ex Steud、Polygounm lapathifolium Linnaeus、Digitaria sanguinalis (Linnaeus) Scop、Stellaria aleine Grimm、 Cyperus rotundus Linnaeus and Conyza canadensis (L) Cronq., on their germinating and emergence in tobacco fields. The results show that the developmental zero and accumulative temperatures are 6.05、3.05、1.49、3.65、3.93℃ and 42.34、53.13、125.96、47.69、78.29DD，7.73、8.23、6.78、7.86、7.86℃ and 46.01、46.96、56.97、39.72、39.07DD， 7.49、6.51、6.70、6.83、6.96℃ and 50.18、57.31、77.92、60.20、51.91DD during absorption to protrusion, germinating and emergence stages, respectively. |
