galvanotropismn.

/ˌɡalvənəʊˈtrɒpɪz(ə)m/

Etymology: < galvano- comb. form + Greek τρόπος turning + -ism suffix.

The phenomenon of curvature produced in growing plant-organs by the passage of electric currents through them; movement produced in plants or animals by the stimulus of an electric current.

ΚΠ

1885 S. H. Vines in Encycl. Brit. XIX. 60 These phenomena are spoken of as ‘galvanotropism’.

1895 Science Progress IV. 101 There is in many cases a remarkable orientation in relation to the current—‘galvanotropism’.

1918 J. Loeb Forced Movements iv. 42 Phenomena of galvanotropism can be observed also in infusorians.

1959 T. H. Savory Instinctive Living iii. 28 Some of them are synonyms—e.g. electrotropism and galvanotropism.

Derivatives

ˌgalvanoˈtropic adj.

ΚΠ

1895 Science Progress IV. 100 The essential fact upon which the galvanotropic effect turns is that current down the animal has a quieting action, current up the animal an exciting action.

1895 Science Progress IV. 101 Fertilised frog's eggs..exhibit remarkable galvanotropic effects.

1918 J. Loeb Forced Movements iv. 41 Galvanotropic reactions are found throughout the whole animal kingdom.

1936 Discovery June 198/1 The planarian Leptoplana variabilis is negatively phototropic and kathodically galvanotropic.
