Abstract: Pot experiment was used to study the effects of Burdock oligosaccharide on the growth,disease index and physiological index in watermelons. In order to ascertain the appropriate concentration of Burdock oligosaccharide inducing the resistance to Fusarium wilts in watermelon. The results suggested that after treated with Burdock oligosaccharide of concentration from 5 to 50 mg/L,the watermelon disease index decreased by the efficacy 22.48%. The fresh weight of per seeding,seeding height,CAT activity,POD activity and SOD activity increased by 4.83%-53.10%,0.14%-22.81%,9.89%-32.62%,24.69%-59.77%,6.19%-12.61% respectively. MDA content and O2· generation rate decreased by 2.63%-23.53% and 7.11%-18.53% after treated with Burdock oligosaccharide at the concentration range from 5 to 30 mg/L. But MDA content and O2· generation rate increased by 3.79% and 5.10% when the concentration of Burdock oligosaccharide was 50 mg/L. Comprehend all the data above,the appropriate concentration of Burdock oligosaccharide applied to watermelon was 20-30 mg/L.

Key words: Burdock oligosaccharide, Induced resistance, Watermelon, Fusarium wilts
