Abstract
BY smearing cotyledon buds of Phaseolus vulgaris (var. non plus ultra) sprouts with heteroauxin paste (C20H18O11N2 + lanolin) so that the cotyledon stalks also come into contact with it, we obtain a prolongation of life of these stalks, which grow longer and larger and remain fresh green, while the rest of the cotyledons afterwards shrivel and change colour (Fig. 1.).
