采后钙处理对冬枣生理和贮藏品质影响的研究

Study on the Effect of Calcium Treatment to Physiology and Fruit Quality in Storage of the Postharvest Dong Jujube

研究了采后钙和钙+赤霉素处理对冬枣贮存过程中品质和生理指标的影响,结果表明:钙处理可降低腐烂率,延缓果实VC含量下降,并有效抑制MAD含量升高,保持SOD、POD、CAT活性;钙与钙+赤霉素处理对冬枣采后品质和生理影响差异不明显。采后钙处理是提高冬枣贮藏品质的有效措施。

The effect of calcium treatment and calcium +GA3 treatment on physiological index and the quality of Dong jujube during storage were studied in this paper. The results showed that calcium treatment could reduce rotten rate, delay the decreasing of VC content, retard the rising of MAD efficiently, and maintain the activity of SOD, POD and CAT. The effect of calcium and calcium +GA3 had not shown any obvious difference. Calcium treatment was an effective measure to raise Dong jujube storage quality.
