Abstract: Abstract: 【OBJECTIVE】Explore the effect of the Apple Fruit broth on inducing resistance of Strawberries to Botrytis cinerea.【METHOD】Sprayed with four strawberries processing, 5 days later Botrytis cinerea were inoculated.6 days after inoculating, disease resistance of different treatments and activity of peroxidase, polyphenol oxidase and β - 1,3 - glucanase were determined.【RESULTS】The results showed that the Tr2 could not only induce resistance of the strawberries on the Botrytis cinerea, its resistance to disease index reached 34.6%, which was significantly higher than the control. Difference between other treatments was not significant. Sprayed with Tr1,Tr2,Tr3, the activities of POD, PPO were higher than control, activity of β-1, 3 - glucanase appeared earlier. 【CONCLUSION】The mixed liquor of 100-fold diluted apple fruit fermentation broth and 0.02mol/mL salicylic acid could induce the better resistance of the strawberry on the Botrytis cinerea. The effect of 100-fold diluted apple fruit fermentation broth was not significant.
