Hyphal growth from spores of the mycorrhizal fungus Glomus caledonius: Effect of amino acids

Abstract

Hyphal growth from spores of Glomus caledonius (Nicol. and Gerd.) Trappe and Gerdemann was stimulated by cystine, glycine and lysine at optimum concentrations of 4.6, 556 and 825 mg l-1 respectively. When all three amino acids were supplied together in water agar, five times more growth was obtained than in the controls. © 1983.
