The soaking of rhizomes, 15–18 cm in circumference in the cultivars 'Black Magic' and 'Mango' as well as 20+ cm in 'Albomaculata', with leaf buds 0.5–2 cm in length, in solutions of benzyladenine at concentrations of 100, 350 and 600 mg × dm-3 lasted 30 and 60 minutes. After this procedure, slightly dried rhizomes were planted into 20-cm pots. Rhizome soaking in BA at concentrations of 350–600 mg × dm-3 for 60 minutes increases the yield of flowers 3–4 times in 'Black Magic', 'Mango', and 'Albomaculata'. BA at concentrations of 350–600 mg × dm-3 retards the flowering of the cultivars 'Black Magic', 'Mango', and 'Albomaculata'. However, at 100 mg × dm-3 it brings flowering forward in 'Mango' and 'Albomacu- lata'. BA at a concentration of 600 mg × dm-3 inhibits the growth of peduncles, while at a concentration of 100–600 mg × dm-3 it causes the formation of longer spathes in the cultivar 'Albomaculata'. In 'Black Magic' at a concentration of 350–600 mg × dm-3 and in 'Mango' at a concentration of 100–600 mg × dm-3, it causes the development of flowers with a smaller weight.
