摘要：对3个不同采收成熟度的‘八月脆’桃在0～1℃低温条件下进行贮藏15d和随后回温3d处理,通过测定果实颜色、硬度、可溶性固形物、失重率和腐烂率等品质指标,以探求桃果实满足冷链贮运和货价期要求的最佳采收成熟度。结果表明,在冷藏15d后,3种成熟度均能保持较高的硬度,SSC变化不明显,成熟度Ⅲ出现轻微褐变和腐烂。在回温3d后,成熟度Ⅰ能够保持较高的硬度,腐烂率最低,但表面着色程度不够,且出现轻微褐变;成熟度Ⅱ的硬度(13.13N)与第Ⅰ组差异不显著(P>0.05),SSC(9.64%)显著高于第Ⅰ组(P<0.05),同时着色充分,腐烂率和褐变率较低,不易失水;成熟度Ⅲ果实软化迅速,色泽发暗,褐变严重,腐烂率高达43.75%,显著高于其他两组。综合评定成熟度Ⅱ(外观绿色稍微减退,阳面少量着色,SSC9.72%,硬度<18.05±0.3>N)的贮运性和货架期的商品率较高,为最适宜的采收成熟度。
Influence of three maturity degree on hardness, soluble solids content, peel and flesh color, internal browning and decay of ‘Bayuecui’ peach during 15days storage at 0℃ and then 3 days shelf-life at 25℃ was studied to ascertain best harvesting maturity degree of peach for the long distance transports .The results showed that hardness and SSC of peach fruit in different maturity degrees were not significantly changed during low temperature storage, but completely mature fruits（fruits at maturity gradesⅢ） were easy to internal browning and decay. During 3 days shelf-life, immature fruits （fruits at maturity grades Ⅰ） kept higher hardness, lower rate of decay, but colored insufficiently on the surface, and also showed slight internal browning. Compared with fruits at maturity grades Ⅰ, the hardness （13.13N） of fruits at maturity grades Ⅱwere not significantly changed, but SSC （9.64%） changed remarkably （P〈0.05）, and colored enough, lower rate of decay and browning, also not easy to lose fruit weight. Fruits at maturity grades Ⅲ＇progress of aging accelerated, colored darkly, internal browning badly, and the rate of decay reached 43.75%, which are remarkable significantly higher than other two. Assessed generally, the rate of commodity of the behavior of storage and transport and shelf-life of fruits at maturity grades Ⅱ（ green fade slightly; colored a little on the surface, SSC 9.72%, hardness 18.05±0.3N） are higher, and it is the optimum harvest maturity .
