Nature of Growth-promoting Activity associated with the Culture Filtrates of Fusarium oxysporum f. lycopersici (Sacc.) Snyd. and Hans.

Abstract

THE growth-promoting activity of the filtrates of the genus Fusarium has long been recognized1–5. Using a bioassay test for auxins, and distilled water as control, Hirata2 detected indolyl-3-acetic acid (IAA) in concentrated filtrates, whereas Venkata Ram3 reported its absence. Their media, in addition to the basal medium (g/1. KH2PO4, 1.5; MgSO4, 1; FeCl3, 0.01; glucose, 25 and nitrogen source, either ammonium sulphate at 2.0 g, or asparagine at 1.99 g and water 1 l. (ref. 5)), were used to culture the fungus to determine indole production.
