Abstract

There has for some time existed a theory regarding organized or possibly unorganized formative substances which flow in different directions in the plant tissue and give to the supposedly polarized meristematic tissues of the plant the power to develop to maintain roots from one given or predetermined extremity and shoots from the opposite extremity only. According to theory – in case of the reversal of the position of these ends in relation to moisture, a corresponding reversal in type of plant organ produced will not ensue and persist. The experiment under discussion in this paper was carried out in an endeavor to determine the appliance of the foregoing hypothesis as regards some woody dicotyledonous Angiosperms – special emphasis being given to Salix Babylonica (the weeping willow).
