Under intermittent mist, single leaf stem cuttings taken from one or two months old green house grown Dioscorea floribunda vines and treated with 1 ppm 2, 4-D and 0.1 ppm benlate or benlate alone gave 80–100 per cent rooted plantlets. The mother plants raised from tuber pieces under green house conditions was found capable of producing 20–30 single leaf stem cuttings at monthly intervals. The plants obtained through this method produced about 10 leaves in a period of two months and the stem cuttings taken from such plantlets gave 90–100 per cent rooted plantlets under the experimental conditions described.
The rooting ability of single leaf stem cuttings taken from field grown vines was found to be unsatisfactory for mass multiplication of D. floribunda plants.
