Experiments on the Cause of Dorsiventrality in Leaves

Nature volume 167, pages 651–652 (1951)Cite this article

Abstract

IN flowering plants, a leaf primordium may be initially centric in shape1; but on further growth it becomes dorsiventral, a phenomenon of which the mechanism is but little understood. Results from experimental treatments of the shoot apex of the potato, Solanum tuberosum, shed new light on this phenomenon. The leaves arise in spiral sequence, with an average divergence angle of 138°. Primordia visible at the time of the operation will be called P1 and P2; P1 being the younger. The first leaf to arise after the operation, but initially invisible, will be called I1.
