Abstract

Effect of citronella essential oil (CEO) fumigation on sprout suppression and quality of potato tubers during storage was investigated. Potato tubers were treated under conditions of single-phase (30 μL L, 0-10 d) and dual-phase (30 μL L, 0-10 d; 30 μL L, 35-90 d) fumigation. Changes in germination rate, weight loss, starch, reducing sugar, gibberellins (GA), and α-solanine were measured. The results showed that CEO fumigation could control sprouting and improve the quality of potato tubers during storage compared to the non-treated tubers. CEO treatments inhibited the degradation of starch and the increase of reducing sugar content. The production of gibberellins (GA) was suppressed, and the levels of α-solanine in the skin and flesh of potato tubers were decreased by CEO fumigation. Dual-phase CEO fumigation had a better effect on sprout suppression than single-phase fumigation, and possesses potential for postharvest application.

摘要

研究了香茅精油（CEO）熏蒸对马铃薯块茎贮藏期间萌芽抑制和品质的影响。在单相（30μL/L，0-10d）和双相（30μL/L，0-10d；30μL/L，35-90d）熏蒸条件下处理马铃薯块茎。测量发芽率、失重、淀粉、还原糖、赤霉素（GA）和α-茄碱的变化。结果表明，与未处理的块茎相比，CEO 熏蒸可控制发芽并改善马铃薯块茎的贮藏品质。CEO 处理抑制了淀粉的降解和还原糖含量的增加。赤霉素（GA）的产生受到抑制，CEO 熏蒸降低了马铃薯块茎皮和肉中α-茄碱的含量。双相 CEO 熏蒸对抑制发芽的效果优于单相熏蒸，具有采后应用的潜力。
