Abstract
Trehalose is a non-reducing disaccharide and a common sugar in fungi, bacteria, and invertebrate animals.
Trehalose also regulates carbohydrate metabolism in higher plants.
We analyzed effects of exogenous applications of trehalose on sweet alyssum (Lobularia maritima), tomato (Lycopersicon esculentum) and muskmelon (Cucumis melo) seedling hypocotyl and root growth.
Seedlings were grown in rolled paper towels in an incubator, germination blotter paper in a growth chamber, or in trays containing potting media moistened with 0, 15, 50, 100 or 200 millimolar concentrations of trehalose.
Tomato hypocotyl and root growth was generally stimulated by trehalose.
Root and hypocotyl growth of alyssum and muskmelon were reduced by roughly 15% by 15 millimolar trehalose, consistent with reports of growth inhibition by trehalose in Arabidopsis thaliana. Exogenously applied trehalose may be useful as a natural growth retardant for bedding plant production.
