Effect of Exogenously Applied L-Tryptophan on Allelochemical Activity of Plant-Growth-Promoting Rhizobacteria (PGPR)

Abstract

The effect of L-tryptophan on root elongation of lettuce seedlings (Lactuca sativa), as well as on allelochemical activity of three species of root growth promoting rhizobacteria (PGPR), was studied under controlled axenic conditions. L-Tryptophan exhibited an hormonelike effect, promoting root elongation of lettuce seedlings at 10−5 and 10−3 mM by ca. 20… (More)
