套袋对黄金梨和丰水梨果实品质的影响 总被引:3,自引:0,他引:3
丰水梨(菊水×八云)和黄金梨(二十世纪×新高)是近年来从日本和韩国引进的砂梨新品种,我国多引种在华北、华中、华东等地栽培,在湖南地区栽培较少。湖南地区梨树生长季节高温多湿,而且雨量主要集中在春秋两季,夏季高温干旱,因而影响了梨果实品质。为研究套袋对果实品质的影响,我们进行了本试验。1 材料与方法 以2 0 0 3年中南林学院“绿之梦”果园的3年生丰水、黄金梨为试材,株行距均为2m×4m。丰水梨5月8日(谢花后15天)套袋,7月14日采收,7月18日测定果实理化性状。黄金梨于5月17日(谢花后18天)套袋,8月18日采收,8月2 2日测定。每个品种… 相似文献

以红富士葡萄为试材,研究了半透明、白色、蓝色、绿色和全遮光等5种果袋对果实品质的影响。结果表明:不同类型的果袋对红富士葡萄果实大小和形状的影响不同,其中,半透明果袋的果实粒质量、纵径和横径最大,分别较对照提高了26.0%、10.5%和8.6%。半透明果袋促进了果实转色,着色率达到100%,且果实红绿色差值最大;仅半透明袋的果实总花色苷含量显著高于对照,较对照提高了77.8%;半透明袋的果实可溶性固形物含量和可溶性糖含量均较对照有所提升,且可滴定酸含量最低,固酸比最高,达到了23.27。综合来看,半透明套袋处理使红富士葡萄果粒增大、转色更好,提升了果实的外观品质,在保持高含糖量的同时降低了可滴定酸含量,提升了果实口感,对果实内在品质也有较好的改良效果。 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

溶菌酶对丰水梨果实贮藏保鲜效果的影响 总被引:9,自引:0,他引:9
以成熟的丰水梨果实为材料,研究了常温条件下0.01%、0.05%和0.15%溶菌酶涂膜处理对丰水梨果实采后生理及保鲜效果的影响。结果表明,贮藏20d后,溶菌酶处理能显著降低果实的失重率、烂果率和呼吸强度,平均比对照分别降低了35%、19.8%和12.2%;溶菌酶处理能有效维持丰水梨果实的内在品质,经溶菌酶处理的丰水梨果实硬度、抗坏血酸(VC)含量平均比对照分别高出0.47kg/cm2和3.5mg/kg,可滴定酸和还原糖含量平均比对照分别高6.6%和9.8%;溶菌酶处理在一定程度上抑制了果实膜透性和丙二醛(MDA)含量的增加,显著抑制了超氧化物歧化酶(SOD)和过氧化氢酶(CAT)活性的降低,贮藏20d后,SOD、CAT活性平均比对照分别高57.1%、37.1%。在3种溶菌酶浓度中,以0.05%浓度溶菌酶涂膜处理效果最好。 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

不同时期套袋对鄂梨2号果实品质的影响 总被引:8,自引:0,他引:8
分别于谢花后20、30、40、50、60d对鄂梨2号[中香×(伏梨×启发),Pyrus pyrifolia Nskai.cv.Eli No.2)]进行套袋处理,结果表明,套袋时期越早,果皮越厚,果面亮度值越高,L值越大,同时果点覆盖值越小,单位面积果点数越少,果面越光洁,外观越漂亮。套袋时期越早,果实平均单果质量有降低的趋势,果实可溶性固形物含量(SSC)、可滴定酸(TA)、可溶性糖(SS)含量降低,风味变淡;同时果实SSC/TA、SS/TA、果肉硬度有增加的趋势。各时期处理果实维生素C含量差异不显著。综合评价得出,鄂梨2号最适宜的套袋时期为谢花后30~40d。 相似文献

采后热处理对枇杷果实冷藏期间品质的影响 总被引:5,自引:1,他引:5
以解放钟枇杷为材料,研究热水和热空气处理对枇杷冷藏(4℃)期间品质的影响。结果表明,38℃36h和48h热空气处理均能够延缓枇杷果实可溶性固形物和出汁率的下降,阻止木质素、硬度、细胞膜透性以及果心褐变指数的上升,显著抑制枇杷果实腐烂的发生,冷藏后枇杷保持较好的食用品质。2组处理相比38℃热空气处理48h的效果较好一点,但是该处理出现了轻微的热伤害。50℃10min、20min热水处理导致严重的热伤害,加剧了枇杷果实的腐烂,在冷藏14d后失去了商品价值,该热水处理不适合枇杷果实的采后保鲜。 相似文献

The commercial expansion of roasted pepper as a high market value product have made that the period of time in which canning industries process the fresh pepper fruits needs to be extended. Fresh sweet pepper (Capsicum annuum L.) destined for industry grown in different sites was cold stored in order to analyse the effect of different sites and storage conditions on the quality of the product at harvest and during storage. Storage during 10 days at 8 °C was the best storage condition to improve quality of pepper destined for industry, because colour was improved, weight loss (1–1.6%) was lower than maximum permissible and decay incidence was only between 0% and 2.3%. Harvest should be delayed until pepper reaches the red state in order to increase the quality of the fruit. However, these results suggest that pepper growers should assure a high content of Ca (>0.6 g kg−1) in the soil to avoid a high incidence of decay during storage when a late harvest is needed to guarantee the enhancement of colour in pepper fruit destined for industry. These storage conditions are in accordance with those found to improve the sensory quality of roasted pepper. 相似文献

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
