PRODUCTION OF GLORIOSA TUBERS FROM SEEDS |

| Abstract:
For the experiments carried out in the years 1981–1984, seeds and tubers of Gloriosa rothschildiana were used. In Poland it is the only species of Gloriosa used in commercial production. The studies dealt with the evaluation of pollen germination and the efficiency of the different pollination methods, the correlation between the leaf shape and the growth of seedlings, as well as the fertilization of plants from small tubers weighing 2–3 g. The influence of lowered temperature on the preservation of germination capacity of pollen was found after 60 days of storage. A higher yield of seeds was obtained in cross pollination than in self-pollination. The assumption that the growth of plants, particularly tuber yield is connected with the leaf shape has not been confirmed. Thus, this feature cannot be taken into consideration in the selection of seedlings. Regarding the tubers growth, the most favourable proved to be the basic fertilization in the amount of at least 250 mg N, 150 mg P and 250 mg K per 1 dm3 of substrate. | |
