中文摘要：
为确定贵州省主要栽培蓝莓品种果实的贮藏性,有利于产地合理选择栽培品种,延长供应期,以‘粉蓝’、‘圆蓝’、‘提芙蓝’、‘灿烂’、‘顶峰’、‘杰兔’、‘巴尔德温’、‘S13’这8个蓝莓品种果实为试材,研究采后冷藏过程中品质变化。结果表明：8个蓝莓品种果实在冷藏期间的贮藏性存在较大差异,腐烂率和质量损失率随着贮藏时间的延长而增大,各品种果实间差异极显著（P〈0.01）;可溶性固形物含量稍有变化;果实的呼吸高峰出现时间有先后且峰值以‘巴尔德温’值最大;还原性糖含量先增加后下降,以‘粉蓝’含量较高且变化平稳,除‘粉蓝’与其他品种差异不显著外（P〉0.05）,其余各品种差异极显著（P〈0.01）;VC含量贮藏前后有较大的提高,‘灿烂’与‘提芙蓝’、‘顶峰’差异极显著（P〈0.01）;果实果皮的花青素相对含量在贮藏期间不稳定,波动变化;整个贮藏期间,以‘灿烂’腐烂较少、VC含量高且呼吸高峰最晚出现,故‘灿烂’是相对最耐贮藏的蓝莓品种,其次是‘顶峰’。
英文摘要：
The quality changes of 8 blueberry cultivars introduced in Guizhou during cold storage were compared and their perservabilities were determine for producer’s selecting of optimal blueberry cultivars and prolonging its supply time.The results showed that there were big differences in the preservability among the blueberry varieties during refrigerated storage and the decay rate and the mass loss rate of the samples increased with the extension of storage time.However,slight changes occurred in the content of TSS while the peak respiration value varied among different cultivars,and ‘Baldwin’ had the highest.An increase followed reduction in the reducing sugar content was observed,and ‘Powderblue’ possessed the highest with slight changes with the exception of ‘Powderblue’ which no significant difference was found compared with other cultivars（P 0.05）.The VC content increased and ‘Brightblue’ showed marked difference from ‘Tifblue’ and ‘Climax’.There was a fluctuation in the content of total anthocyanins during cold storage.Of the investigated cultivars,‘Brightblue’ showed lowest decay index,highest content of VC,and the longest peak respiration time and thereby,has the highest postharvest quality.The best cultivar suitable for storage is ‘Brighblue’ No.1 followed by ‘Climax’.
