Abstract

Abstract:

Postharvest strawberry (Fragaria ananassa Duch cv. Darselect) fruits were treated with 0.05% or 0.1% and the changes of superoxide dismutase (SOD), catalase (CAT) and ascorbate peroxidase (APX) activities, superoxide (O2·) production rate, hydrogen peroxide (H2O2) accumulation, VC content and respiration rate in treated fruits were investigated during storage at 4 ℃. Results indicated that both 0.05% and 0.1% 1-hexanol treatments significantly inhibited the respiration rate of strawberry fruits, maintained high levels of SOD, CAT, APX activities and VC content, reduced the production rate of O2· and the accumulation of H2O2, and thus the fruit senescence was delayed. Comprehensive evaluation demonstrates obvious superiority of 0.05% 1-hexanol treatment over 0.1% 1-hexanol treatment.

Key words: strawberry, 1-hexanol, active oxygen species, fruit senescence
