| 摘 要： | 研究了不同浓度的水杨酸处理对番茄后熟衰老影响。实验结果表明:与对照相比,0.5mmol/L的水杨酸处理可有效降低果实的乙烯释放量和呼吸强度,并可增加番茄果实的抗坏血酸过氧化物酶(APX)和过氧化物酶(POD)活性,降低相对电导率和腐烂率,保持果实原有颜色和硬度,从而延迟衰老进程;而1mmol/L的水杨酸处理尽管也在一定程度上增加了果实抗病相关酶活性,却刺激了呼吸代谢,加速果实转红和衰老进程。

| Abstract: | In this paper,the effects of different concentration of salicylic acid treatments on postharvest ripening and senescence of tomato were investigated.The results indicated that compared with control,0.5mmol/L salicylic acid treatment effectively inhibited respiration rate and ethylene production,increased APX and POD activities,decreased the relative conductivity,maintained fruit color and firmness.Therefore,it delayed the senescence process.However,1 mmol/L salicylic acid treatment increased disease resistance related enzymes,stimulated the respiration,accelerated the rate of turning red,ripening and aging. |

| Keywords: | tomato salicylic acid enzymes related with disease resistance afterripening and senescence |
