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 ‘Albomaculata’. 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.
The effect of BA and GA3 on the yield and the quality of flowers and leaves of Zantedeschia was assessed in researches. The aim of the present research was to assess the effect of a mixture of benzyladenine and gibberellic acid in a solution used for rhizome soaking as well as of various duration times of this practice on the growth and flowering of the ‘Albomaculata’ and ‘Black Magic’ cultivars. In the experiment water solution containing benzyladenine at concentrations of 100, 350 and 600 mg·dm-3 was used combined with gibberellic acid at a concentration of 150 mg·dm-3. Rhizomes, 15–18 cm in circumference in 'Black Magic' cultivar and 20+ cm in 'Albomaculata' cultivar, with leaf buds 0.5–2 cm in length, were soaked for 30 and 60 minutes. Rhizome soaking in a BA and GA3 mixture increased the yield of flowers in the ‘Black Magic’ and ‘Albomaculata’ cultivars, but delayed their flowering, and the flowers developing from rhizomes had shorter peduncles. Besides, in ‘Black Magic’ cultivar the weight of flowers decreased. The application of a BA and GA3 mixture reduced the yield of leaves in ‘Albomaculata’ cultivar. However, they had a higher greenness index and a higher protein and sugar content.
