摘要

本研究采用多效唑(PBZ)和脱落酸(ABA)处理山楂植物，分析其酶促和非酶促抗氧化反应的变化。非酶抗氧化剂如抗坏血酸在ABA处理的植物中下降。但在PBZ处理的植物中，它增加了。虽然PBZ和ABA处理均显著提高了-生育酚含量，但PBZ处理植株中-生育酚含量更高。酶促抗氧化剂如抗坏血酸过氧化物酶和超氧化物歧化酶也增加了处理。与对照植物相比，两种生长调节剂均显著提高了过氧化氢酶活性。总之，我们的研究结果表明，低浓度的PBZ和ABA可以作为增加药用植物防御机制的潜在工具。

Antioxidant potential of Ocimum sanctum under growth regulator treatments

In this study, Ocimum sanctum plants were treated with paclobutrazol (PBZ) and Abscissic acid (ABA) to analyze the changes in the enzymatic and non-enzymatic antioxidant responses. Nonenzymatic antioxidants like ascorbic acid decreased in the ABA treated plants. But it increased in the PBZ treated plants. Although both PBZ and ABA treatments considerably increased the -tocopherol content, it was more in the PBZ treated plants. Enzymatic antioxidants like ascorbate peroxidase and superoxide dismutase were also increased by the treatments. Catalase activity was increased by both growth regulators to a significant extent when compared with the control plants. In conclusion, our results indicated that the PBZ and ABA applications at low concentrations could be used as potential tools to increase defense mechanisms in medicinal plants.
