摘要
研究不同浓度水杨酸(SA)、茉莉酸甲酯(MeJA)和壳聚糖(CTS)对番木瓜防御酶活性的影响。结果表明:SA、MeJA、CTS能提高番木瓜叶片相关防御酶的活性,其中喷施SA处理的POD、PAL、PPO、几丁质酶以及β-l,3-葡聚糖酶的活性高于喷施MeJA和CTS的处理。同一处理中,0.5 g/L SA、0.05 mmol/L MeJA和1%CTS处理的POD、几丁质酶以及β-l,3-葡聚糖酶活性较高。
The effects of exutory on papaya relative defense enzymatic activities were studied.The results showed that the relative defense enzymatic activities increased by salicylic acid（SA）,methyl jasmonate（MeJA） and chitosan（CTS）.The activities of POD,PAL,PPO,chitinase and β-1,3-glucan enzymatic of SA were higher than that of other treatments.The activities of POD,chitinase and β-1,3-glucan enzymatic of the treatment 0.5 g/L SA,0.05 mmol/L MeJA and 1% CTS were the highest in the same exutory treatments.
