不同品种风味甜瓜果实品质比较 总被引:1,自引:0,他引:1
以风味4号、风味5号甜瓜为主要试材,雪里红甜瓜为对照,比较不同品种甜瓜果实品质差异.试验结果表明,雪里红单瓜质量达到2 kg以上,属于大果型,风味4号和风味5号属于中小果型.风味5号的可溶性固形物和可溶性糖含量最高,风味4号的游离氨基酸和可滴定酸含量最高,雪里红的可溶性蛋白和维生素C含量最高;而糖酸比则是风味5号居中,雪里红最高,风味4号最低.风味4号的蔗糖和有机酸含量均高于其他两个品种,风味5号果糖含量最高,雪里红的柠檬酸含量仅为风味4号的1/3、风味5号的1/2.风味4号的17种游离氨基酸和氨基酸总含量普遍高于风味5号和雪里红,而风味5号与雪里红的氨基酸成分与含量相当.综合比较,风味5号甜瓜果实大小、酸甜口感适中,营养品质较好. 相似文献

为筛选出适合潮湿多雨的闽南地区设施栽培的优质厚皮甜瓜品种,解决福建省云霄县甜瓜产业发展中品种良莠不齐的问题,以西周蜜25为对照,综合比较长香玉、东方蜜1号、金尊1号和西周蜜17号的含糖量、口感、风味、产量及适应性。试验结果表明:西周蜜17产量高,口感细脆,风味佳;东方蜜1号口感好,综合抗性强,不易裂果;均适应闽南地区湿度大的生产气候条件。这2个品种因其甜度适中的脆肉型口感而符合当地市场消费习惯,可引进作为闽南地区设施栽培的品种,适度推广种植。 相似文献

A novel melon cultivar (‘Flavor No. 3’) containing high acid concentration as well as high sugar content in the mature fruit was successfully bred out. The aim of this study is to determine the main organic acids present in this novel melon and to clarify the mechanisms of acid accumulation. Fruit development and acid accumulation patterns in ‘Flavor No. 3’ were compared with those of a conventional low-acid melon, ‘Xuelihong’. The titratable acidity (TA) and organic acids in fruits were measured at different developmental stages. There is a positive correlation between TA and citric acid content in ‘Flavor No. 3’, indicating that citric acid is the predominant organic acid present throughout the fruit development. The activities of the enzymes involved in citric acid metabolism, including phosphoenolpyruvate carboxylase (PEPC), citrate synthase (CS), aconitase (ACO), isocitrate dehydrogenase (IDH), malate dehydrogenase (MDH), and malic enzyme (ME), were determined. Although no single enzyme was responsible for citric acid accumulation throughout the fruit development, the activities of ACO and ME were positively correlated with citric acid concentration in the two cultivars from 5 to 25 days after pollination (DAP). Moreover, ACO and ME activities in ‘Flavor No. 3’ increased over time and were higher than those in ‘Xuelihong’, resulting in citric acid accumulation in the fruits of ‘Flavor No. 3’. Although a sharp decrease in ACO activity took place after 25 DAP in the fruits of ‘Flavor No. 3’, the earlier accumulation of citric acid was sufficient enough to maintain the high acid concentration until the melon fruits became mature. 相似文献

本试验以新疆南疆地区特色甜瓜——“比斜克其”作为材料,通过培养皿滤纸法用苦豆子不同部位(叶片、茎秆、豆荚和种子)浸提液对“比斜克其”种子进行处理,分别测定种子发芽和幼苗生长情况。试验结果表明,对照组种子萌发率、发芽势和发芽指数均大于苦豆子处理组,其中种子浸提液处理的萌发率、发芽势和发芽指数等指标均小于其他4个处理。对照组幼苗的平均胚轴长度、平均主根长度、平均侧根数目、平均鲜质量和平均干质量均小于苦豆子处理组,其中茎秆浸提液处理的胚轴长度、主根长度、侧根数目以及鲜质量均大于其他处理组。因此苦豆子植株不同部位浸提液对“比斜克其”种子萌发具有抑制作用,其中种子浸提液的抑制作用最强;但对“比斜克其”幼苗及根系生长均具有促进作用,其中茎秆浸提液促进作用最强。因此不建议将苦豆子作为底肥在“比斜克其”播种之前施用,而应在种子萌发之后作为追肥施用。 相似文献
