The determination of which of the two reproductive pockets of Lemna perpusilla will produce the first daughter frond under non-flowering conditions, or the flower under inductive conditions, is related to asymmetric gradients within the mother frond which may be the result of the asymmetric position of the axillary frond. Treatments that encourage vigorous growth of axillary fronds may overcome the normal situation of asymmetry and cause a morphological symmetry which is qualitatively different from the symmetry induced by treatments (TIBA) which prevent the development of axillary fronds. The origin and maintenance of asymmetry in Lemna are discussed.
