thermonasty

/ ˈθɜːməʊˌnæstɪ /

noun

botany a nastic movement in response to a temperature change, as occurs in the opening of certain flowers

I shall presently describe the effects of both positive and negative thermonasty, in diurnal movements of flowers.

I shall for convenience distinguish the differential growth under temperature variation as Thermonasty proper.

Further tests will be given later, to distinguish the phenomenon of Thermonasty from that of Thermo-geotropism.

Two different classes of phenomena arise from variation of temperature—Thermonasty and Thermo-geotropism.
