PHOTOPERIODIC ADAPTATION TO LATITUDE IN XANTHIUM STRUMARIUM [PDF]
Photoperiodic responses of collections of Xanthium strumarium L., grown from seed obtained in nature at various localities in North America between latitudes 20° and 45.5° N, were examined. The critical night length was found to vary noticeably with latitude of origin, from about 7.5 hr in the northernmost strains to above 10 hr in the southern strains.
