套袋对梨果实品质的影响 总被引:7,自引:0,他引:7
用膜袋、膜袋加双层纸袋、带膜纸袋、双层纸袋和蜡袋,对黄金梨等5个品种进行套袋试验。结果表明,套袋能显著减少果锈的发生,明显改善果实外观,但果实可溶性固形物含量下降,品质有所降低。对极易发生果锈的黄金、翠冠等绿皮梨品种,宜选用膜袋加双层纸袋或用带膜纸袋,以减少果锈,提高其商品性;对果锈少的圆黄、华山、爱甘水等褐皮梨品种,宜选用双层纸袋或蜡袋,避免果实品质明显下降。 相似文献

叶面喷施硼肥对葡萄柚果实品质的影响 总被引:1,自引:0,他引:1
《现代园艺》2015,(17)
为改善葡萄柚果实品质,在其果实发育期(花后30~180天),叶面喷施不同浓度水平(0.2%、0.4%、0.6%)的硼肥,研究不同叶面硼肥处理对葡萄柚果实营养品质和外观品质的影响。结果表明,适量叶面喷施硼肥促进葡萄柚果实总糖、可溶性固形物、Vc、果肉硬度、单果重和可食率,降低了果实总酸含量。0.2%~0.4%范围内,葡萄柚果实品质随喷施浓度的提高而增加。综合试验结果,缺硼葡萄柚果树,可在果实发育期叶面喷施4~5次0.4%的硼砂溶液果实品质效果最好。 相似文献

不同套袋材料对红杧6号杧果果实品质的影响 总被引:2,自引:1,他引:2
研究了不同套袋材料对红杧6号杧果果实外观、果皮色素、果皮色泽及果实内在品质的影响。结果表明,采用白色单层袋套果后,青熟和完熟时,白色单层纸袋处理的叶绿素、类胡萝卜素质量分数较低,花青苷和类黄酮质量分数均较高,果皮亮度、色彩浓度和色度角均较高或最高,使果皮在青熟时呈紫红色,完熟时呈桃红色。白色单层袋套果后,果实的内在品质如维生素C、可溶性固形物、蔗糖、葡萄糖、果糖质量分数最高,内在品质最佳。外黄内黑复合纸袋果皮叶绿素、类胡萝卜素、花青苷、类黄酮质量分数均较低,果皮亮度、色彩浓度均最高,色度角最低,使果皮在青熟时呈浅黄色,完熟时呈橙黄色,但果实内在品质比白色单层袋差。因此,建议红杧6号杧果用白色单层纸袋进行套袋。 相似文献

Effects of bagging on fruit development and quality in cross-winter off-season longan 总被引:1,自引:0,他引:1
Wei-Hai Yang Xiao-Chuan Zhu Jian-Hua Bu Gui-Bing Hu Hui-Cong Wang Xu-Ming Huang 《Scientia Horticulturae》2009
Clusters of cross-winter off-season longan (Dimocarpus longan Lour) cv. Chuliang were bagged with three types of bags: perforated translucent plastic bag (TPB), white adhesive-bonded fabric bag (WAFB) with about 70% light transmittance, and black adhesive-bonded fabric bag (BAFB) with <10% light transmittance. Bagging treatments began at 34 days after anthesis and continued until harvest. The results showed that bagging modified the microenvironment for fruit development. Bagging with TPB was most effective in increasing humidity, and air moisture within TPB maintained above 90% from 2 weeks after bagging. Bagging with BAFB or WAFB increased humidity most of the time, and the effect was more prominent when the weather was very dry (RH < 60%). All bag types tended to increase temperature and promoted fruit development, resulting in larger sized fruit. Bagging tended to promote early fruit drop but reduced late fruit drop, and the final fruit retention rate was not significantly affected by bagging. Bagging with different materials showed differential effects on incidence of fruit cracking. WAFB and BAFB reduced cracking incidence significantly as compared to the control (5.1% and 11.6% vs 32.8%). Sugar content was not significantly affected by bagging but organic acids including vitamin C (Vc) were considerably affected. Concentration of malic acid, the dominant organic acid in longan aril, was 605.6, 830.0, 1161.0 and 1428 μg/g FW in TPB, BAFB, WAFB and the control. Vc in the aril was significantly reduced by BAFB (108.4 μg/g FW), slightly increased by WAFB (183.9 μg/g FW) and significantly increased by TPB (264.5 μg/g FW) as compared with the control (174.7 μg/g FW). Pericarp of fruit bagged with TPB had a slightly higher content of Vc (1337 μg/g FW), while those bagged with BAFB (873.6 μg/g FW) and WAFB (787.4 μg/g FW) had significantly lower Vc contents than the control (1243 μg/g FW). The responses of oxalate and Vc contents in the aril and the pericarp to bagging treatments showed an opposite trend. The results suggested that WAFB increased fruit size and fruit retention rate while significantly reduced fruit cracking incidence and could be a promising practice for cross-winter longan production. 相似文献

套袋对翠冠梨果皮特征及品质的影响 总被引:4,自引:1,他引:4
翠冠为南方主栽梨品种之一,自然生长状况下果面极易形成锈斑,严重影响其外观品质。通过对翠冠梨进行不同类型果袋的套袋处理,系统定量研究了套袋条件下果皮的形态特征、果实外观和内在品质的变化。结果表明,套袋处理显著提高了无绣果和少绣果的比率,增加了果面亮度,改善了果实外观色泽,减小了果点直径,减淡了果点色泽。在电子显微镜下可清晰看到套袋使果面光洁平滑,龟裂程度远小于未套袋果面。套袋处理普遍降低了果实可溶性固形物含量;不透光袋显著提高了果肉石细胞含量。在外观品质改善上以双层透光蜡纸袋效果最好。研究结果将有助于今后对翠冠梨果实袋的正确选择和使用。 相似文献

不同纸质果袋对湖景蜜露桃果实品质的影响 总被引:4,自引:2,他引:4
为探索提高桃果实品质的适宜果袋,以6年生湖景蜜露桃为试材,选用橘红色袋、黄色袋、白色袋和报纸袋等4种不同纸质的果袋对果实进行套袋处理,以不套袋作对照,研究了不同纸质果袋对成熟果实外观和内在品质特性的影响。测定了果重、可溶性固形物、可滴定酸含量、果实色差等物理性状和果实糖、有机酸、花青苷、香气物质的含量。结果表明,白色袋能提高糖和香气物质含量的积累,增加果实风味,但果实外观暗红并涉及果肉;报纸袋果实外观粗糙,不清洁,且香气和酸含量低;黄色袋果实综合品质性状优于报纸袋和白色袋;橘红色袋能改变果实果皮底色,加快花青苷降解,使果实外观光亮(L值大),高雅美观,糖、酸及香气物质等品质指标也相对较高。 相似文献
