摘要:

考察外源硝普钠(sodium nitroprusside,SNP)处理对茄子品质的影响。结果表明:12.5、25、50 μmol/LSNP处理可有效保持茄子的感官品质、延缓营养物质的下降,其中以25 μmol/L SNP处理最佳。25 μmol/L SNP处理能够减缓茄子萼片的褐变度,延缓果肉相对电导率的上升,抑制果肉中VC、可溶性蛋白、总酚含量的下降,提高过氧化氢酶(CAT)、过氧化物酶(POD)活性。

Abstract:

The effect of sodium nitroprusside (SNP) solutions at concentration levels of 12.5, 25 and 50 μmol/L on the
quality of eggplant was investigated. SNP at 25 μmol/L significantly reduced the browning of sepals and inhibited the
decrease in relative conductivity and the contents of VC, soluble protein and total phenols. The activities of antioxidant
enzymes, including catalase (CAT) and peroxidase (POD) were induced by SNP treatment.

Key words: sodium nitroprusside, eggplant, VC, soluble protein, catalase
