Experimental and Analytical Studies of Pteridophytes XXXVI. Further Experiments on the Developmental Potentialities of Leaf Primordia in Dryopteris aristata Druce

Abstract

The curve of growth in area of Pelargonium leaves against time is strongly asymmetrical, and cannot be fitted by the usual logistic curve. It is shown that the Gompertz curve provides an excellent fit, and the significance of its parameters is discussed.
