Propagation Technology of Paphiopedilum bellatulum

Abstract

Propagation Technology of Paphiopedilum bellatulum with 2 experiments were studied at Chiangrai Horticultural Research Centre during 2005-2009. The first experiment was aimed to find out the suitable media for seed germination and development of Paphiopedilum bellatulum. The second experiment was studied on the suitable media for seedling development. It was found that the best media for seed germination was ½ MS added with 2 mg/l of BA, 0.5 mg/l of NAA and 2 g of peptone while ½ Jittrapan II media gave the second rank. Round-white Protocorms sized 1.0 mm were exposed to 1,000 lux of light for 2-3 weeks. The whith protocorms then enlarged and changed to green colour and developed meristem. The green protocorms were transferred to the same media and after 3-4 weeks rearing 1-2 leaves were developed. Those protocorms were transferred to 2 media to find fit in well with the suitable media for seedling development. It was found that 2 modified media gave the same results for Paphiopedilum bellatulum development in terms of fresh weight, number of roots and root lengths after 6 months rearing.
