A 10 to 20% stimulation of growth in Lemna gibba L. G3 occurred following the addition of 0.5 to 3 m M glycolate or glyoxylate, although concentrations of 5 m M or higher were inhibitory. Glyoxylate gave a higher stimulation than glycolate. The stimulating effect on growth was obtained in media with or without 2% added sucrose. A higher stimulation was obtained when the plants were cultivated in open flasks in comparison to cultivation in flasks plugged with cellulose stoppers, which presumably retarded gas exchange.
