The drought tolerance of wild Axonopus compressus germplasm resources was studied and the drought resistance of each A. compressus plant was found to have a direct relationship with its habitat. The A. compressus plants which had better drought tolerance were usually distributed on sloping ground, waysides etc., while plants which had poor drought tolerance were usually distributed in damp habitats such as river banks and bottoms.
