摘要: 经1 000μg·mL - 1β - 氨基丁酸(β-aminobutyric acid, 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3 d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。

关键词: 辣椒, β - 氨基丁酸, PR蛋白, 酶活性

Abstract: Pathogenesis-related ( PR) proteins in the intercellular fluids of three pepper cultivars leaves were induced after treatments with 1 000 μg·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.

Key words: Pepper, β-aminobutyric acid, PR protein, Enzymes activity
