摘要:

研究采前一周喷施不同质量分数Ca(NO3)2溶液(1.0%、1.5%、2.0%)对贮藏期‘京欧1号’品种欧李果实腐烂率、糖酸含量及糖酸比值动态变化的影响。结果表明,采前喷钙降低了贮藏期欧李果实的腐烂率,增加了不同种类糖酸含量,特别是在贮藏45 d时,喷施1.5% Ca(NO3)2处理果实腐烂率为8.4%,并且果实中的蔗糖、葡萄糖、山梨糖醇、苹果酸、琥珀酸、酒石酸、柠檬酸和草酸含量以及糖酸比显著高于对照及其他喷钙处理。采前喷钙处理利于欧李果实的贮藏,以采前一周喷施1.5% Ca(NO3)2处理效果最好。

Abstract:

The effects of spraying with different concentrations of Ca(NO3)2 solution (1.0%, 1.5%, and 2.0%) at one week
before harvest on decay incidence and the contents of sugar and organic acid as well as their ratio in fruits of the ‘Jing’ ou
1’ cultivar of Chinese dwarf cherry (Cerasus humilis (Bge.) Sok.) were studied during storage. The results indicated that
preharvest calcium spray reduced the incidence of decay and increased the contents of sugar and organic acid during storage.
On the 45th day of storage, the decay incidence of the fruit treated with 1.5% Ca(NO3)2 preharvest was only 8.4% and the
contents of sucrose, glucose, sorbitol, malic acid, succinic acid, tartaric acid, citric acid and oxalic acid and sugar/acid ratio
in the treatment group were significantly higher than in the control and other calcium treatments. These findings suggest that
preharvest calcium treatment is helpful to preserve the quality of Chinese dwarf cherry fruits during storage and the best
application regimen is spraying 1.5% Ca(NO3)2 at one week preharvest.
