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.

High frequency direct shoot proliferation was induced from the shoot tip explants derived from the in vitro grown seedlings of a critically endangered and horticulturally important ground orchid Phaius tancarvilleae (L'Her) Blume. Shoot tip explants cultured on solidified MS with alone or combination of various concentrations of NAA and BAP produced shoots and multiple shoots. The maximum number of healthy shoots was observed on MS with BAP (1.0 mg/l) with an average of 13.3 shoots per culture in 20 weeks; where shoot multiplication was initiated after 4 weeks of culture. Regenerated shoots rooted on MS with various concentrations of NAA, IAA, IBA. MS with NAA (0.5 mg/l) was the most appropriate condition for rooting. The well developed in vitro rooted plantlets were hardened successfully in the potting mixture containing cocopeat and sphagnum moss in the ratio of 2 : 1.   Key words: Mass propagation, Phaius tancarvilleae, shoot multiplication   D.

In Vitro Shoot Regeneration

An efficient and reliable protocol of in vitro shoot regeneration must be first established to have a successful genetic transformation. As a member of legume family, alfalfa is very difficult for direct shoot regeneration. There is no published information on direct shoot organogenesis, although success has been well documented on embryogenesis, which must go through callus stage. Different plant growth regulators at various concentrations were evaluated for callus initiation, development, and direct shoot regeneration. Multiple shoots were produced directly from each individual explant. This will provide an efficient means for production of transgenic alfalfa plants. Therefore, genetic transformation of Medicago germplasm will be significantly expedited.
