Growth Curves of the Gramineæ

Article metrics


IN my paper read at the Belgian Congrès National des Sciences at Brussels in 1930, I gave a short account of my measurements of the growth-energy of Triticum vulgare, Hordeum vulgare, Secale cereale, and Avena sativa, in accordance with growth (velocity) curves in general. I followed accurately each day, at the same time, all shoots which issued from one single seed. The curves plotted on rectangular coordinates always gave a straight line between the points of inflexion (arithmetical series), and the Archimedes spirals constructed revealed for each kind of plant, during the whole of its life, two distinct growth-waves.
