PLANT REGENERATION FROM SOMATIC CELLS OF VANILLA PLANIFOLIA
Young stems of Vanilla planifolia were cultured on Ms medium containing 1.0μg/mL BAand 5.0 
μg/mL NAA,and white calli occurred in 40 days,Such calli could be subcultured manytimes for 
propagation。The calli were transferred onto MS medium supplernented with 2-3 μg/mL BA 
and 0.5μg/mL NAA,and a large numberof protocorms were induced in 30 days.Theprotocorms 
subcultured on half strength MS medium containing 1.0μg/mL BA and 0.5 μg/mL IBA 
produced many plantlets in 30 days,and multiple shoot buds were regenerated from 
theplantlets.Rcots of the plantlets were induced in 20 days on half strength MS medium 
containing1.0μg/mL IAA and a 100% success was attained in field establishment,
