细胞能量与果实的成熟、衰老、生理紊乱和收获后的抗病性密切相关。以南果梨果实为材料，在100 mg L-1酸性苯并拉尔- s -甲基（ASM）中浸泡10 min，室温风干，20℃贮存12 d，研究ASM对果实能量代谢相关酶活性的影响。本研究还研究了ASM对接种膨胀青霉的梨果实损伤发育的影响。用蒸馏水作对照。结果表明，ASM浸渍处理显著降低了白蜡菌侵染后梨果实的损伤直径。ASM浸渍处理提高了梨果实ATP含量、能量电荷、H+-ATP酶、Ca2+-ATP酶、细胞色素C氧化酶和琥珀酸脱氢酶的活性。上述结果表明，采后ASM处理通过调节能量代谢诱导南果梨果实抗病。
Cellular energy is closely related to fruit ripening, senescence, physiological disorder and disease resistance after harvest. Nanguo pear fruit were immersed in 100 mg L-1 Acibenzolar-S-methyl (ASM) for 10 min, then air-dried at ambient conditions and stored for 12 d at 20 degrees C to investigate the effect of ASM on the activity of enzymes involved in energy metabolism. The effect of ASM on lesion development of the pear fruit inoculated with Penicillium expansum was also investigated in this study. Same treament with distilled water was used as control. The results demonstrated that ASM dipping treatment significantly decreased lesion diameter on the pear fruit inoculated with P. expansum. ASM dipping treatment enhanced ATP content, energy charge, the activity of H+-ATPase, Ca2+-ATPase, cytochrome C oxidase and succinic dehydrogenase in pear fruit. These results suggest that postharvest ASM treatment induced disease resistance in Nanguo pear fruit through mediating energy metabolism.
