Abstract

Abstract Radish (Raphanus sativus) and Swiss Chard (Beta vulgaris) seedlings, grown hydroponically, exhibited significantly greater increases in height and weight in medium containing α-mannoside supplemented with calcium and manganese salts, than in control treatments lacking one or more of those components. Furthermore, seeds sown on medium containing α-mannoside plus Ca2+and Mn2+showed accelerated germination. Calcium and manganese are necessary to maintain the protein conformation of mannose-binding lectins. In the presence of those cations, glycosides displace specific sugars bound to lectins, making them available to support plant growth. Keywords: plant growthseed germinationlectinglycosidecalciummanganese ACKNOWLEDGMENT We greatly appreciate the clarity of expression contributed by our colleague and past co-author in the series, Professor Emerita Valrie A. Gerard. Elucidation of concepts is brought to the forefront by her profound understanding of the field.
