title: Photoperiodic, induction of senescence in xanthium plants.
abstract: Xanthium plants placed under photoinductive conditions were accelerated in their senescence whether or not the plants had a capacity to produce flowers and fruits. Thus, the role of the mobilization influence of these organs on the senescence of certain monocarpic plants can be questioned.
