Determination of Uni-and Trifoliolate Leaf Form in Fenugreek

Abstract

The leaves of the Trifolieae are trifoliolate except for the first which usually is single (unifoliolate). Hereditary deviations from this pattern have recently been described by Bingham (1966).t He described Medicago 8ativa L. plants in which all leaves were unifoliolate, and others in which all leaves, including the first, were trifoliolate. This communication reports some observations on fenugreek, Trigonella foenum-graecum L., which bear on the physiological conditions favouring one or the other developmental pathway.
