摘 要 ：为探明温度及成熟度对无花果贮藏期生理指标的影响,以新疆早黄无花果为试材,研究在常温和低温条件下,2种成熟度无花果的呼吸速率、乙烯释放、过氧化物酶(POD)活性、过氧化氢酶(CAT)活性、超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量的变化。结果表明,贮藏温度对无花果果实采后生理指标的影响有显著差异,低温可显著延长果实贮藏寿命和货架期,缓解有害代谢物MDA的累积,降低防御酶系的活性。不同成熟度的果实采后,过氧化酶活性及MDA含量无显著差异,但低成熟度果实呼吸及乙烯高峰出现时间与高成熟度果实相比推迟4~10h。因此,适当低温及低成熟度有利于新疆早黄无花果的采后保鲜贮藏。本研究为无花果的保藏运销提供了理论依据。

Abstract:To investigate the effects of temperture and maturation on postharvest physiology indexes of fruits, respiration intensity, ethylene evolution, POD activity, CAT activity, SOD activity and variations in MDA content were studied during the storage of two maturity Xinjiang Zaohuang fig fruits with room temperature and low temperature. The results showed that the effects of storage temperature on postharvest physiologies proved to be significant difference, low temperature can significantly prolong the fruit’s storage life and shelf life, relieve the accumulation of MDA and reduce the activity of defensive enzymes. There was no significant difference in peroxidase activity and MDA content with different post-harvest fruit maturity, but respiration peak and ethylene peak of low maturity fruit were 4 to 10h delayed comparing to higher maturity fruit. Therefore, low temperature and low maturity is propitious to postharvest preservation of Xinjiang Zaohuang fig fruits. This research would provides a important theoretical significance on the storage of fig fruit.
