Fungal endophyte isolates tested for production of IAA.
Endophytes were grown in liquid media in the presence (+) or absence of 0.1% tryptophan (Trp) for 21 days.
Indole-3-acedtic acid (IAA) detected in parts per million (ppm).
ND = not detected.
Ten, five day old seedlings nonsymbiotic (NS) or symbiotic with SaltSym or TempSym1were assessed for IAA.
