Inverted Polarity in Salix babylonica L.
Recueil des travaux botaniques néerlandais , Volume 31 - Issue 1/2 p. 210- 222
In a recent article, entitled: Eine botanische Polaritatstheorie, Went (1932) discusses the place of origin of the growth substance and the direction of its transport. He states that such transport can be due to: a. a pressure drop inside the plant b. a concentration drop of the growth substance c. a potential drop, in case the transported substance is ionised. He considers that the conditions which cause the polarity phenomenon are not likely to be influenced by external conditions and that polarity cannot be inverted and gives indeed the impression of having relied to a large extent on this assumption.
