Content of flavone is the hightest in browning callus. It is supposed, that suppose which the last pace of synthesize flavone is in brovwing callus. SDS-PAGE cataphoresis electrophoresis show protein has big change from differentiating callus to browning callus. The change may has relation with change of enzymire activiation of control flavone synthesize.

Influence of the concentration of Cr in the leachate and quantity of Pb(CH3COO)2 of Pb(NO3)2 on the reaction of synthesizing yellow chrome was also studied. Finally, according to the criterion and standard method in GB3184-82, some yellow chrome synthesized in the experiments was sampled and the concentration of PbCrO4 in these samples was determined. The following conclusion can be drawn from these experiments.
