Influence of plant growth regulators and tuber weight on sprouting and flower number of glory lily [Gloriosa superba (L.)]

Abstract

The research work was carried out to induce the sprouting percentage and number of flowers plant-1 through different growth regulators in glory lily. Before planting tubers are treated with different concentrations of growth regulators concentration viz., GA3 (250 and 500 ppm), CCC (500 and 1000 ppm), Ethrel (250 and 500 ppm), NAA (50 and 100 ppm), MH (500 and 1000 ppm) with control were applied on two different tuber sizes viz., W1 (average weight of 90-100 g tubers) and W2 (average weight of 140-150 g tubers). Among the various treatments were used, GA3 @ 500 ppm with an average weight of 140-150 g tubers was found to influence sprouting percentage (85.90 per cent) followed by GA3 @ 250 ppm with an average weight of 140-150 g tubers. Ethrel @ 500 ppm with an average weight of 140- 150 g tubers was found to have highest number of flowers plant-1 (41.50).
