Abstract
The aim of present study was to investigate the effect of different storage temperatures on physiology, quality, antioxidant activity and shelf life of avocado fruits. The optimum mature avocado fruits were harvested (150 days after fruit set) from accession CHES-HA-I/I and CHES-HA-VII/I, and brought to the laboratory. These fruits were stored at 5, 9 and 12 °C with 90–95% relative humidity (RH) and at ambient condition (26–32 °C with 55–62% RH). The results showed that, low-temperature storage significantly reduced the physiologic and biochemical processes in the fruit. Lower physiologic loss in weight (PLW), slower rate of ripening, reduced respiration and ethylene production and higher carbohydrates, protein and crude fat content were recorded in low-temperature storage, whereas higher antioxidant activity in terms of total phenolic content (TPC), free radical scavenging activity (FRSA) and ferric reducing ability of plasma (FRAP) was found in avocado fruits stored at ambient temperature. It was also observed that chilling injury (CI) developed in fruits stored at 5 °C. From the present study, it is concluded that among different low temperatures, fruits stored at 9 °C had better storage life with more fruit quality, higher antioxidant activity and least spoilage as compared to other temperatures.
研究了不同贮藏温度对牛油果果实生理、品质、抗氧化活性和保质期的影响。从加入hes - ha -I/I和hes - ha - vii /I中收获最佳成熟牛油果(坐果后150 d),并带到实验室。这些果实分别在5℃、9℃和12℃、90-95%相对湿度(RH)和环境条件(26-32℃、55-62% RH)下保存。结果表明,低温贮藏显著降低了果实的生理生化过程。结果表明,低温贮藏的牛油果生理性失重(PLW)较低,成熟速度较慢,呼吸和乙烯产量减少,碳水化合物、蛋白质和粗脂肪含量较高,而在总酚含量(TPC)、自由基清除能力(FRSA)和血浆铁还原能力(FRAP)方面具有较高的抗氧化活性。在5℃贮藏条件下,果实也发生了冷害(CI)。本研究结果表明,在不同低温条件下,9℃贮藏的果实贮藏寿命较长,果实品质更好,抗氧化活性更高,腐坏率最低。
期刊介绍:
Acta Physiologiae Plantarum is an international journal established in 1978 that publishes peer-reviewed articles on all aspects of plant physiology. The coverage ranges across this research field at various levels of biological organization, from relevant aspects in molecular and cell biology to biochemistry.
The coverage is global in scope, offering articles of interest from experts around the world. The range of topics includes measuring effects of environmental pollution on crop species; analysis of genomic organization; effects of drought and climatic conditions on plants; studies of photosynthesis in ornamental plants, and more.
