摘要

The effect of ten different doses of nitrogen (N), phosphorus (P) and potassium (K) was studied on growth and flowering of micropropagated bulblets of Lilium sp. (Asiatic hybrids, cultivar 'Gran Paradiso' and 'Sanciro') for two growing seasons. A ratio of 10: 20: 20 NPK showed the highest growth of bulblets and flowering percentage. Tissue culture-raised bulblets grown on optimal dose of NPK (10: 20: 20) exhibited better growth and higher flowering percentage (50) compared to 25 percent flowering in conventionally raised bulblets. A long tradition of growing flowers exists the world over. It is, however, only recently that economic aspects of growing flowering plants have been exploited both in the domestic and in the international market. Till recently, raising of flowers has been by the traditional farmers, but in an unorganized market, profits are comparatively low. As a result, very little effort was made for improving the quality of the planting material. Further, traditional methods of propagation are far too slow resulting in long gestation period between the release of the variety and those being commercially available to the farmers. Tissue culture plays an important role in propagation of plants that are constantly in high demand, bulking-up stocks of recent introductions, multiplication of pathogen-free stocks and for cloning of mother plants for hybrid seed production.
