摘要：

Chitosan has been proposed to elicit defense responses in plants. In this study, we evaluated the potential roles of chitosan as a fertilizer supplement to stimulate Begonia ?— hiemalis Fotsch ???Schwabenland Red??? growth and resistance to gray mold caused by the fungus Botrytis cinerea. We evaluated the effect of treatment with fertilizer containing various ratios of N, P, and K in combination with different concentrations of chitosan on plant growth and disease resistance. Of the sixteen treatments examined, the treatment consisting of an N:P:K ratio of 2.8:1.0:1.4 and chitosan concentration of 0.10 g?·L
