After this procedure, slightly dried rhizomes were planted into 20-cm pots. Rhizome soaking in BA at concentrations of 350每600 mg ℅ dm-3 for 60 minutes increases the yield of flowers 3每4 times in 'Black Magic', 'Mango', and 'Albomaculata'. BA at concentrations of 350每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每600 mg ℅ dm-3 it causes the formation of longer spathes in the cultivar 'Albomaculata'. In 'Black Magic' at a concentration of 350每600 mg ℅ dm-3 and in 'Mango' at a concentration of 100每600 mg ℅ dm-3, it causes the development of flowers with a smaller weight. %K Zantedeschia %K cultivation %K growth regulators %U http://pbsociety.org.pl/journals/index.php/aa/article/view/1351
