DETERMINATION OF BACTERIALLY DERIVED AUXINS USING A MICROPLATE METHOD

Rapid and efficient methods for determining the ability of soil and rh izosphere bacteria to produce key metabolites which are useful in grow th promotion or suppression of plant growth are needed. A microplate m ethod was developed and compared to a standard method for assays of au xin compounds produced by bacteria. The microplate method was similar to the standard method in accuracy of determination, required less che mical reagents, and considerably reduced the time required for analyse s.
