Abstract

Variations in abscisic acid (ABA) and indole-3-acetic acid (IAA) concentrations were studied in Funalia trogii (Berk.) Bondartsev & Singer and Phanerochaete chrysosporium Burds. ME446 subjected to salt stress. The levels of ABA and IAA were determined by gas chromatography (GC) and UV-VIS spectrophotometry. The levels of hormones vary in the regulation of growth and in response to stress. It was found that ABA concentrations were higher in the salt stressed groups than in the control groups, whereas IAA concentrations were lower. These results show that, in fungi, ABA concentrations are positively and IAA concentrations negatively correlated with salt stress.
