摘要
对3个不同采收期的瑞蟠四号桃进行冷藏,通过测定果实颜色、大小、硬度、可溶性固形物、可滴定酸、褐变指数等理化指标,以探索适宜蟠桃长期贮藏保鲜的采收期。结果表明,3个采收期桃的硬度、可溶性固形物、可滴定酸含量在贮藏过程中变化趋势相同,没有显著差异;瑞蟠四号桃在采收期2[硬度,(4.4±0.3)kg/cm2;可溶性固形物,(9.9±0.8)%;可滴定酸,0.1366%左右]采收有较好的果实品质,可贮藏长达2个月以上。
Influence of three harvesting time on peel color, mean fruit mass, flesh firmness, total soluble solids, titratable acid and internal browning of fiat peach No.4 cold stored was investigated to study best harvesting time of fiat peach for long storage. The results showed that three harvesting time had not significantly affected to change trend of flesh firmness, total soluble solids and titratable acid. Flat peach No.4 of the second harvesting time （Firmness, 4.4 kg/cm^2; TSS, 9.9%;TA, 0.1366%） had better quality and could be stored for two months.
