Research on Keeping Quality of Different Flesh Types of Prunus persica L.Niu Liang, Wang Zhiqiang, Liu Shu'e, Song YinhuaAbstract: Effects of post-harvest cold storage and Modified Atmosphere Package on fruit hardness, weight losing and soluble solid content of different peach or nectarine varieties were investigated. The results showed that:(1) There were obviously differences of fruit hardness among varieties of different flesh types. In room temperature, FH of '24-30' and 'Zhongtao No.2' went down slower than 'Zhongyoutao No.5' and 'Zhongyoutao No.10'. In cold storage, '24-30', FH of Zongyoutao No.5' and 'Zhongyoutao No.10' descent quickly after 2 weeks of storage while that of 'Shuguang' and 'Zhongtao No.2' quickly descent just after storage.(2) MA package could effectively slow down the decreasing of FH. There were obvious differences among different varieties while 'Zhongyoutao No.10' was less sensitive than others.(3) Soluble solid content went down after harvest and the procedure was slower in lower temperature. In room, MA package seems accelerate the descendent of SSC.
采用不同肉质类型的桃、油桃果实为材料,对采后低温和自发气调包装等对果实硬度、失重和SSC含量等的变化进行了研究,结果表明:(1)不同类型桃、油桃采后果实硬度变化差异较大,常温下24-30和中桃2号果实硬度下降较慢,而中油桃5号、10号较快,在冷库低温条件下,24-30、中油桃5号和中油桃10号两周后硬度出现迅速下降,而曙光和中桃2号在贮藏后即迅速下降,带皮硬度与去皮硬度之间有一定差异,但变化趋势基本一致;(2)MA包装能有效地延缓采后桃、油桃果实硬度的降低,在常温及低温条件下均是如此,不同肉质类型间差异明显,曙光和中桃2号非常敏感,而中油桃10号则不太敏感,即MA包装对其果实硬度降低的延缓没有其它品种明显;(3)采后桃、油桃果实的SSC含量均有一定的降低,低温下该过程较慢,MA包装在常温下有加剧SSC下降的趋势,低温下则不明显,这可能与常温下采后立即进行MA包装不利于&田间热&及呼吸热的及时散发而加剧呼吸有关。

Huang-hua' pear fruit was a typical climacteric fruit after harvest, and the fruit senescence-related factors, such as LOX activity, 02" content, AOS activity, ACC synthase activity, ACC content, ACC oxidase activity and ethylene production, changed with peaks at 20 "C. The activities of LOX, AOS, ACC synthase, ACC oxidase and the accumulation of O2 ", ACC content and ethylene synthesis were inhibited when stored at 1癈. And the severity of flesh floss and fruit decay was lightened. Low temperature combined with polyethylene film bag packing (PEF1 and PEF2) could further decrease the rate of weight loss, flesh floss, and fruit decay and keep preferable freshness. When PEF1 and PEF2 packing fruits were transferred to shelf life at 20 "C after storage at 1癈. The activities of LOX, AOS, ACC synthase, ACC oxidase could be suppressed and the accumulation of 02 , ACC content and ethylene production were slowed down to a certain extent, especially during the shelf life after 60 d storage. PEF1 and PEF2 packing fruit could maintain higher firmness as well, and the effects became more distinct along with the storage period, there existed no significant difference between PEF1 and PEF2 treatments.
试验结果表明,在20℃下,LOX活性、O2-水平、AOS活性、ACC合成酶活性、ACC含量、ACC氧化酶活性及乙烯的生成,均呈峰形变化;1℃处理可抑制LOX、AOS、ACC合成酶、ACC氧化酶的活性和O2-、ACC的积累,抑制贮藏果实的乙烯合成,减轻果肉发绵和果实腐烂。1℃下贮藏的果实,若结合不同聚乙烯薄膜袋(PEF1和PEF2)小包装,可以进一步降低果肉发绵率和果实腐烂率,保持果实新鲜度;当果实经过一段时间贮藏后,转移到20℃下,在货架期间,PEF1和PEF2对果实成熟衰老各个相关因子均有不同程度的抑制效应,主要表现在贮藏60d后的货架期间,同时维持较高的果实硬度,对硬度的影响随着贮藏时间的延长愈加明显,PEF1和PEF2处理效果之间无显著差异。

Golden pear could keep high quality over 100 days if stored at 5 centigrade, because the low temperature had influenced it in many aspects:(1) Made weight loss ratio lower than normal, and no fruit rot appeared;(2) Keep high fruit firmness all through the storage;(3) Respiratory climacteric came forth later than that which stored at room temperature, and the peak was lower than normal;(4) Activity of LOX and PG were inhibited, so the process of fruit senescence was delayed effectively.
7.5℃低温贮藏可以使黄金梨果实贮藏期延长至100天以上,并长期保持其优良商品特性,主要在以下几方面对果实产生影响:(1)降低黄金梨果实的失水率、防止烂果的发生;(2)延缓果实硬度下降的进程;(3)延迟果实呼吸峰的到来,并使峰值降低;(4)有效抑制黄金梨果实中LOX、PG的活性,从而延缓果实的衰老过程。

Through the result we know that it is lower on the firmness and higher on the rot, there is a big difference between the upper(0-40cm)and middle and floor(40-120cm)in the stack, so if controlled the height of stack about 60cm, and shorten the time in the stack ,there is a little decline on fruit rot.
另外本文还对车厢内果实的硬度和腐烂率进行了初步的研究,结果表明,随堆放位置的下降果实硬度下降,果实腐烂率则相反呈上升趋势,且车厢上层(0-40cm)与车厢中下层(40-120cm)果实的硬度和腐烂率之间有显著性差异,因此建议降低装车高度(60cm左右),减少果实在车厢内的堆放时间,可大大降低果实的腐烂率。

In Fuji apple, Starking apple and Feicheng peach, 1-MCP slowed the conversion of TA content and SSC, maintained the ratio of sugar to acid and reduced the flavors loss in later storage time. 1-MCP also reduced the chilling rate and fruit weight loss of Feicheng peach stored at 0℃, but accelerated the decay of Feicheng peach and the detachment of grape berry from peduncle stored at 20℃. The effect of 1-MCP on the decay of strawberry was related to temperature: alleviated at 20℃ and enhanced at 0℃.
在富士、红星和肥城桃果实中,1-MCP处理都延缓了果实可滴定酸和可溶性固形物含量的转化,维持了果实贮藏后期糖酸比,抑制了果实贮藏后期风味的损失。1-MCP处理还减轻了O℃贮藏的肥城桃果实冷害的发生和果实失重,但促进了20℃下肥城桃果实的腐烂和巨峰葡萄的脱粒现象。1-MCP对草莓果实腐烂发生率的影响则与温度有关:20℃下减轻,0℃下加重。

MCP could effectively delay the softening of climacteric fruit, such as Starking and Fuji apples and Feicheng peach, but as different fruits had different softening mechanism, the mechanism of 1-MCP inhibiting different fruit softening was different: in Starking apples, the key enzyme to the softening is endo-and exo-PG, while during Feicheng peach fruit softening, the key enzyme was EGase before the 20th d and endo-PG after 20th d during storage at 0℃. 1-MCP inhibited fruit softening mainly by inhibiting PG activity in Starking apple while in Feicheng peach, by inhibiting the activity of EGase in the earlier storage time and endo-PG in the latter time. It was also found that LOX accelerated the initiation of the softening and was regulated by ethylene and 1-MCP in apple and peach.
2.1-MCP能较好的延缓红星、富士和肥城桃等跃变型果实硬度的下降,但是不同品种/树种的果实软化机理不同,1-MCP抑制其软化的机理也不一致:在红星果实中,对软化起主要作用的酶一直为内切和外切两种PG,而在肥城桃软化过程中,前20d以纤维素酶活性起主要作用,20d后软化以内切PG为主。1-MCP主要通过抑制红星果实中PG酶活性来抑制果实硬度的下降;在肥城桃果实中,1-MCP通过抑制前期纤维素酶和后期内切PG活性,延缓了果实硬度的下降。

The results showed that wind precooling could inhibit the respiration intensity of plum fruit, while the two precooling methods had little effect on the formation of ethene. The firmness and soluble solid content decreased on storage. The precooling methods had little effect on the firmness of fruit, but wind precooling could relieve the decrease of to a certian extent. The two varieties of plum fruit both became rotten in the late period of storage, the rot with ice precooling was higher than wind.
结果表明,风预冷可抑制'黑宝石'和'安哥诺'李果实的呼吸速率,但这2种预冷方式对果实乙烯释放量的影响不明显;随着贮藏时间的延长,'黑宝石'和'安哥诺'李果实的硬度和SSC含量均下降,这2种预冷方式汁果实硬度的影响不大,但风预冷可在一定程度上缓解果实SSC含量的下降;在贮藏后期,2品种李果实均表现出腐烂症状,冰水预冷果实的腐烂症状明显高于风预冷。
