Abstract

The effect of different combinations and concentrations of exogenous hormones on differentiation of floral buds from cells in different positions on the same perianth explants were studied, and the contents of internal IAA and Z+ZR in different of postitions of the same perianth were analyzed. The results of experiment showed that all cells in the upper, middle and lower parts of the sameperianth explant could be induced to differentiate floral bud, but with different frequencies under different concentrations of growth hormones or growth regulators.
