HOW DO INFLORESCENCES OF LUPINUS POLYPHYLLUS (FABACEAE) RE-ESTABLISH THEIR POSITION AFTER ARTIFICIAL BENDING?

The c orrect position of the inflorescence is vital for the pollination success. Many plants have physiological reorientation mechanisms based on the effects of hormone auxin, which is secreted in apical meristems and induces negative gravitropism. The younger the inflorescence is, the more important it is to restore its verti-cal position in the fastest possible way to maximize pollination success. Thus, we investigated the effect of the absence of inflorescence’s apical part and inflorescence age on its reorientation and position of bending point. As an object of investigation, the invasive Lupinus polyphyllus was chosen, since the position of the flowers along the axis makes the plant convenient for manipulation. Removal of the apex does not influence the restoration of orientation relatively to the ground. Younger inflorescence tends to have a greater part of them reoriented. The reoriented part of inflorescence mainly contained unopened or partly opened flowers at the moment of the initial bending by experimenters.
