[Studies on the plant hormones produced by 5 species of endophytic fungi isolated from medicinal plants (Orchidacea)].
OBJECTIVE
To study the plant hormones produced by 5 species of endophytic fungi isolated from medicinal plants and to illustrate the mechanism on endophytic fungi stimulating the growth of plants.


METHODS
Extracting plant hormones from mycelia and its culture solution with organic solvent, and detecting them by HPLC.


RESULTS
One or more plant hormones [GA3 (Gibberellin), IAA (Indoleacetic acid), ABA (Abscisic acid), Z (Zeatin), ZR (Zeatin riboside)] were detected from the mycelia and its culture solution.


CONCLUSIONS
The plant hormones produced by the endophytic fungi are important materials that may be used to reveal the mechanism of endophytic fungi stimulating the growth of medicinal plants (Orchidacea).
