Corm sections and shoots derived from plants in culture formed multiple shoots on Murashige and Skoog's (MS) medium supplemented with 10 mg benzyl adenine/litre. Subculture of shoot tips in fresh medium of the same composition increased the number of shoots produced with each culture cycle. Shoots cultured 1 mo in MS medium without growth regulators initiated roots and were readily transplanted in soil. With subculture every 2 mo, 200 000 plantlets can be derived from an explant in 10 mo
