Effect of growth regulators on flower and leaf yield of the calla lily (Zantedeschia Spreng.)

摘要

To assess the effect of a mixture of benzyladenine and gibberellic acid on the quality and yield of flowers and leaves of cvs Albomaculata, Black Magic and Mango, their tubers were soaked before planting for 30 min in a water solution with 100-600 ppmBA and 150 ppm GA_3. The BA + GA_3 mixture application resulted in 2.5-3.5 times as many flowers in comparison to the control plants, which did not affect the quality of flowers and the yield of leaves. The leaves, however, showed higher greenness indexand protein quantity.
