采前喷布AVG对苹果贮藏寿命和品质的影响 总被引:1,自引:0,他引:1
<正> AVG(aminoethoxyvinylglycine),即氨基乙氧基乙烯基甘氨酸,是乙烯生物合成的抑制剂。在采收前数周至1周对苹果树或梨树喷布100-500 mg/L的AVG水溶液,对其果实在贮藏期内的乙烯生成有强烈的抑制作用,因而能延缓 相似文献

乙烯是诱发和促进苹果果实成热和衰老所必需的激素,如何抑制果实中乙烯的生成和排除贮藏环境中的乙烯是目前采后生理及果蔬贮藏保鲜研究的一个重要方面。国外一些关于苹果低乙烯贮藏的报道多限于在0℃气调库条件下进行。本文主要研究在土窑洞变温条件下,红星苹果气调帐内乙烯累积浓度的变化及降低帐内乙烯浓度对红星苹果品质的影响。一、材料和方法 相似文献

贮藏温度对藤牧1号苹果果实保鲜效果影响研究 总被引:1,自引:0,他引:1
以藤牧1号苹果果实为试材,研究了贮藏温度对果实酶活性及理化性状的影响。结果表明:20℃和5℃温度条件下果实纤维素酶、PG、LOX、淀粉酶活性变化均表现前期逐渐增加,出现峰值后逐渐下降的变化趋势。20℃条件贮藏的果实不但纤维素酶、PG、LOX、淀粉酶活性始终高于5℃条件的果实,酶活性峰值出现时间也较早。果实贮藏期间,果肉原果胶含量逐渐降低,可溶性果胶含量逐渐增加,纤维素含量逐渐下降。20℃条件贮藏的果实的纤维素和果胶物质的含量变化率均高于5℃条件贮藏的果实。随着果实中纤维素和果胶物质的变化,果实逐渐软化,果肉硬度降低,失重率增加,品质下降。 相似文献

随着苹果总产量的增加和人民消费水平的不断提高。果品质量越来越受到重视,质量差价也越来越明显。但当前部分果区还存在着果个偏小、果形不正、着色不良、果面不光洁、风味较淡、肉质松绵、香气不足等问题,在部分果农中还存在着只片面追求高产而忽视质量的现象。为此,必须转变观念,通过各种措施提高苹果的综合品质,这样才能在口趋激烈的果品竞争中求得生存,才能不断开拓国际市场,增加收益。 1 选择优良品种,适地适栽 当前苹果新品种不断出现,品种更新速度加快,品种差价越来越明显。陕西目前苹果生产 相似文献

ABSTRACT This research was conducted to determine the king versus lateral fruit thinning effects on yield and fruit quality of ‘Elstar’, ‘Granny Smith’, ‘Starkrimson Delicious’, ‘Ultra Red’, ‘Topred’, and ‘Jonagold’ apple (Malus domestica Borkh.) cultivars grafted on MM106 rootstock in 2002-2003. Removal of the king fruit (KFR) treatment partially increased the yield in ‘Jonagold’, ‘Elstar’, and ‘Granny Smith’ cultivars while the effects were different by years in “Starkrimson Delicious”. Leaving of the king fruit (KFL) treatment gave better results in the ‘Topred’ cultivar, and similar effects were obtained from both treatments in ‘Ultra Red’ cultivar. Non-significant differences were obtained from both treatments with respect to fruit weight in the ‘Topred’, ‘Starkrimson Delicious’, ‘Jonagold’ and ‘Granny Smith’ cultivars. Leaving of the king fruit treatment increased the fruit weight significantly in ‘Elstar’ and ‘Ultra Red’ cultivars in 2002. The values of fruit flesh firmness (lb), total soluble solids content (%), pH, titratable acidity (%), total and invert sugar quantity (g/100 g?1) were not found to be significantly different between the treatments with a few exceptions. The ‘KFR’ treatment that removed the dominant effect of the king fruit can be recommended for the ‘Elstar’ and ‘Jonagold’ cultivars because this treatment increased the yield and did not decreased the fruit weight significantly in these cultivars except for ‘Elstar’ in 2002. On the other hand ‘KFL’ treatment can be recommended for the ‘Granny Smith’, Topred’ and ‘Ultra Red’ cultivars. Although this treatment decreased the yield of ‘Granny Smith’ it increased the mean fruit weight 45.6-62.7 g in the two experiment years. ‘Starkrimson Delicious’ did not show clear response to the treatments. 相似文献
