Abstract

SUMMARY crop types with respect to their weed flora. (3) The weed flora was closely related to crop types. In particular, there was a close relationship between the growth period of crops and their weed flora, especially the frequency of therophytes. The results are discussed in relation to the growth period of the crop, the life form of the weed species and agricultural practice. (4) It is concluded that numerical methods are a useful tool in understanding the phytosociology and ecology of weed flora.
