The following PGRS were searched for in the extracts of the
selected two isolates using the HPLC analysis employing the
method of Tien et al. (1979): auxins including indole-3-acetic
acid (IAA) and indole-3-pyruvic acid (IPYA), gibberellic acid
(GA 3 ), and the cytokinins isopentenyl adenine (iPa), isopente-
nyl adenoside (iPA) and zeatin (Z). Five independent replicate
flasks of each isolate were analyzed.
