中文摘要：

经1000μg·mL^-1 β-氨基丁酸（β-aminobutyricacid，BABA）诱导处理后，3个辣（甜）椒品种叶片细胞间液的蛋白质电泳分析表明，寄主植物经BABA处理3d后病程相关蛋白（PR）被诱导产生。对叶片中β-1，3-葡聚糖酶、几丁质酶和过氧化物酶活性动态测定表明，升高幅度辣椒品种高于甜椒品种。

英文摘要：

Pathogenesis-related （PR） proteins in the intercellular fluids of three pepper cuhivars leaves were induced after treatments with 1 000μg·mL^-1 β-aminobutyric acid （BABA）. The results of enzymic assays showed that activities of β-1, 3-glucanases, chitinases and POD were heightened in hot peppers more than that in sweat peppers.
