嘧菌酯处理对哈密瓜采后抗病性的影响
Effect of Azoxystrobin Treatments on Postharvest Disease Resistance of Hami Melon Fruit
摘要
Abstract
[Objective] Disease Resistance with 250 mg/L Azoxystrobin treatment was mainly studied in this paper, technical reference was provided for the control of posthavesr hami meilon. [ Method ] Xizhoumi26hao hami melon as materials, they were soaked with Azoxystrobin 50、150、250、300 mg/L for 3mins , and storaged at room temperature after nature dry, disease resistance mechanism of postharvest hami melon with Azoxystrobin treatment was studied . [Result] Test results showed that; decay rate,respiration and ethylene release quantity were restrained effectively, The lignin content,catalase (CAT), peroxidase(POD), phenylalanine ammonia - lyase ( PAL) and β - 1, 3 - glucanase ( GHU) were increased by 250mg/L azoxystrobin treatment at the latter of storage, and the decrease of Exo chitinase ( GHT) activity were restrained. [ Conclusion ] Therefore the results suggested that the enhanced disease resistance in harvested hami melon by azoxystrobin treatment could result from the activition of the disease - related defense enzyme activity.关键词
