Improvement of micropropagation protocol of Phalaenopsis sp. for the method of direct shoot regeneration from nodes of floral spikes

This paper succesfully investigated the possibility of modification of the micropropagation protocol of Phalaenopsis sp. with an aim to simplify the procedure and reduce the costs. The obtained results show that some medium components can be succesfully omitted (coconut water, glutamine, 2-morpholinoethanesulfonic acid) and some of them (peptone) can be replaced with a cheaper constituent (soy flour) while preserving the quality of the obtained microplants. The multiplication rate was 7,6 shoots per explant after the period of 150 days of cultivation in vitro. On the same medium 60% of explants were rooted and roots were mostly well developed.
