PRODUCTION OF BABIANA RINGENS CORMS FOR FORCING AS A FLOWERING POT PLANT
Production and flowering of Babiana ringens corms was assessed in three experiments. Flowering performance of nine corm weight grades (0.03, 0.12, 0.24, 1.0, 3.1, 5.2, 7.0, 9.1, 11.0 g), corm production from seed sown in a greenhouse and outdoors from December to May was assessed, as well as the effect on corm growth of three planting densities (112, 224, and 336 corms/m2) in the greenhouse, or outdoors. All corms ≥1 g flowered. The time to flowering for plants grown from corms ≥3 g averaged 153 days. However, the time to flowering increased for lower corm weights. The minimum corm planting weight for consistent forcing was ≥3 g. Seed germination was high for sowing dates from December to April, with an average germination rate of 75%. Corm weights were higher for plants grown from outdoor than greenhouse-grown seed, with corms reaching 2.4-2.9 g in the first year. When seed-derived corms were grown for a second season, all plants reached a flowering size. For outdoor grown plants a mean lifted corm weight of 10.4 g was achieved across all densities.
