Abstract
Extract from onion bulbs and diffusate from roots of onion seedlings were fractionated by column chromatography. The stimulatory effects of the different fractions of onion extract on sclerotial germination ofSclerotium cepivorum were studied. The sugar fraction was the most stimulatory, whereas, the amino acid fraction was not effective. Paper chromatographic analysis revealed the presence of glucose, fructose and no amino acids in the root diffusate. These two sugars and 13 amino acids were identified in the onion extract. When various sugars and amino acids were supplied individually to autoclaved soil, only glucose, fructose, mannose and maltose effectively induced sclerotial germination. Partial stimulation occured in nonsterile soil amended with high glucose concentrations.
