Abstract: The preparation of β (1→3) glucan by the alkalilysis method from Saccharomyces cerevisiae was studied in this paper.It was indicated that β (1→3) glucan was the major component of the acquired products by IR analysis.It could make the cucumber plants resistance to B.cinerea when used for seed soaking.The plants resistance could be maintained for 14 days.The rates of the diseased leaf of the plants induced with 500 mg/L and 1000 mg/L glucan were 37 9%-57.9% and 38.4%-59 0% lower than that of the control,respectively.The relative immunization efficiencies were 75 0%-90 9% and 77 5%-92.1%,respectively.

Key words: β-(1→3)-D-glucan, Induced resistance, Gray mold
