Recent research has shown that the plant is a useful medicine for bacterial dysentery. Aviculare is een samenstelling van de woorden avi, wat ´vogel´ betekent en culare. Primary and secondary dormancy may be controlled by different molecu Many pioneer weed seeds associated with agricultural systems, such as Polygonum aviculare, require light stimuli to terminate dormancy and give way to the germination process (Baskin & Baskin, 1985; Taylorson, 1987; Benech‐Arnold et al., 2000).Light stimuli are perceived by seeds through photoreceptors, particularly those corresponding to the phytochrome family.
