BT23094Response of spiny cocklebur (Xanthium spinosum) and common cocklebur (X. strumarium) seed germination to environmental and soil factors
Information on factors affecting spiny cocklebur (Xanthium spinosum) and common cocklebur (X. strumarium) seed germination could help us determine their potential distribution in different regions and their effective control strategies. Maximum germination of both spiny cocklebur and common cocklebur was at neutral pH. Spiny cocklebur germination was less sensitive to high and low pH, salinity, flooding and surface burial than was common cocklebur germination, indicating that it may be better adapted to the broader range of conditions.
