摘要/Abstract

摘要： 为研究叶面喷施草酸、水杨酸(SA)和BTH对甜瓜植株防御酶活性的影响，在甜瓜二叶期用不同浓度的草酸、水杨酸(SA)和BTH对甜瓜植株进行处理。结果表明：经草酸处理后，甜瓜植株体内的β-1,3-葡聚糖酶和POD活性均较对照植株有明显升高，在处理后9天达到高峰，β-1,3-葡聚糖酶活性与对照相比提高了2.7~3.9倍，POD活性比对照提高了3.5~4.8倍。但草酸处理并没有引起PAL活性的提高。用水杨酸(SA)和BTH处理植株，甜瓜植株体内的β-1,3-葡聚糖酶、POD和PAL活性较对照植株也有明显的提高，在处理后7天均达到高峰，其中β-1,3-葡聚糖酶活性比对照提高了1.9~3.8倍；POD活性提高了3~5.5倍；PAL活性提高了1.8~5.2倍。

Abstract: In order to research the activities of defense enzymes in muskmelon, the oxalate, salicylic acid and BTH were used to treat 2-leaf muskmelon leaves in different concentrations. The results showed that after treated by oxalate, the activities of β-1,3-glucosidase and peroxidase (POD) in 2-leaf muskmelon leaves were higher than that in the control. And the β-1,3-glucosidase activity increased 2.7 to 3.9 times, POD activity increased 3.5 to 4.8 times 9 days after the treatment. But PAL activity could not be induced by oxalate. After treated by SA and BTH, the activities of β-1,3-glucosidase, POD and PAL were higher than that of the control obviously. And the β-1,3-glucosidase activity increased 1.9 to 3.8 times, POD activity increased 3 to 5.5 times and PAL activity increased 1.8 to 5.2 times 7 days after the treatment.
