以Irwin杧果为试材,研究外黄内黑复合纸双层果袋对生长发育过程中果皮叶绿素、类胡萝卜素、花青苷、类黄酮含量与相关代谢酶活性变化影响及相关性。结果表明,随着果实发育成熟,花青苷含量在果实发育中呈低—高—低的变化趋势。套外黄内黑双层袋显著降低了果皮叶绿素、类胡萝卜素、花青苷和类黄酮含量;PAL活性在果实发育60d就达到最高,随后降低,完熟时降至最低;CHI活性随着果实的发育成熟有所降低,DFR活性前期变化平缓,在完熟时升至最高;UFGT随果实发育成熟降至最低;外黄内黑复合纸袋显著抑制了PAL、CHI、DFR和UFGT活性。果皮花青苷、类黄酮与CHI呈极显著正相关,类黄酮与UFGT呈显著正相关。说明Irwin杧果皮着色可能是各种色素与CHI和UFGT等作用的结果。 相似文献

利用切片观察法、显色法和比色法对佛焰苞中花色素的分布情况、组分及含量进行了初步分析。结果表明:红掌佛焰苞中主要含有类黄酮(包括花青素苷、黄酮和黄酮醇)、叶绿素和类胡萝卜素3类色素。大部分品种中类黄酮主要分布于上下表皮细胞中,‘萨维尔’等少数品种的栅栏组织中也有类黄酮分布;而叶绿素和类胡萝卜素则分布在栅栏组织中。各色系均含有类黄酮,红色系比其它色系含有更多的花青素苷,绿色系则含有叶绿素;参试品种中只有棕红色品种‘热带之夜’含有少量类胡萝卜素。花青素苷和叶绿素是佛焰苞显色的主要因素,总体上总花青素苷和叶绿素含量与颜色明度L*呈负相关,而与彩度C*呈正相关,即随着总花青素苷含量的增加,红色和粉红色佛焰苞的红色色调加强,叶绿素含量增加可使绿色和白色佛焰苞的绿色和黄色色调加强。 相似文献

以凤仙花的9种花色株系为试材,通过盆栽试验,测定花瓣、叶片和茎干的色素物质、非结构性碳水化合物及可滴定酸含量,并进行了相关性分析.结果表明:花瓣越红,花青苷含量越高,且差异显著;橙色、浅红和白色花瓣的类黄酮和总酚的含量显著低于深红色系花瓣;粉红、浅红和紫红色花瓣类胡萝卜素含量显著高于其它色系花瓣;但紫色花瓣中花青苷含量较低,说明其主要色素物质可能不是花青苷.此外,在叶片和茎干内也检测到了少量的花青苷,花色越红其含量越高.各试材间叶片叶绿素a含量差异不大,而红色花瓣的株系叶片叶绿素b和叶绿素a+b含量显著高于白色和浅红色株系.通过相关性分析发现,花瓣可溶性糖含量与花青苷含量呈显著正相关;类黄酮含量与叶片淀粉和可滴定酸含量呈显著正相关,而与叶片淀粉含量呈极显著负相关;花瓣总酚含量与可滴定酸含量呈显著正相关;类胡萝卜素含量与叶片可滴定酸呈极显著正相关,而与茎千淀粉含量呈极显著负相关. 相似文献

从6～8月各品种果实着色前夕开始,每隔7d采摘红色的"大红李"、青色的"萘李"和黑色的"黑宝石"3个品种的果实,测定并比较了各品种果实在成熟过程中果皮色素变化的差异及与果肉可溶性糖和可滴定酸的相关性。结果表明:在果实成熟过程中,"黑宝石"和"大红李"花青苷含量都呈现不断上升的趋势,而叶绿素含量呈略微下降趋势;"萘李"的花青苷含量极低,且变化不大,叶绿素含量则先升后降;3个品种类胡萝卜素含量均缓慢上升。"萘李"叶绿素含量和类胡萝卜素含量一直极显著或显著地高于"大红李"和"黑宝石",而花青苷则极显著或显著地低于2个品种。"黑宝石"和"大红李"花青苷含量与可溶性糖含量分别呈极显著和显著正相关,而与酸含量呈显著或极显著负相关;2个品种类胡萝卜素含量与可溶性糖含量呈显著正相关,而与酸含量间相关性表现不一致;2个品种叶绿素含量与糖、酸含量的相关性均不显著。"萘李"3种色素的含量与糖、酸含量间的相关性均不显著。说明"大红李"和"黑宝石"着色可能由花青苷含量决定,而青色的"萘李"则由类胡萝卜素和叶绿素含量决定。 相似文献

The purpose of this study was to investigate the effect of glucose on glucosinolates, antioxidants and metabolic enzymes in Brassica sprouts. After glucose treatment, total glucosinolates, phenolics and anthocyanin contents and antioxidant activity were significantly enhanced in Chinese kale and pak choi sprouts, while only the anthocyanin and ascorbic acid contents were increased in radish sprouts. These results indicate that glucose treatment has selectively improved the nutritional compounds in different Brassica sprouts. 相似文献

Anthocyanins are responsible for the colour of many fruits, vegetables, flowers, and coloured-leaved trees. Ornamental kale (Brassica oleracea L. var. acephala DC) is widely cultivated for its colourful inner leaves. To investigate the relationship between the degree of colouration and anthocyanin distribution, content, and composition in ornamental kale, the authors studied the pigment characteristics of five cultivars with different coloured leaves (white, pink, red, purple, and purple-black). Microscopy observation, spectrophotometer, and high-performance liquid chromatography-mass spectrometry (HPLC-MS) analysis of fresh inner leaves revealed that pink, red, and purple colourations were associated with high levels of anthocyanin, while purple-black was the result of the combination of anthocyanins and chlorophyll. In the coloured cultivars, anthocyanins were abundant mainly in the first and second cell layers below the epidermis in both the hypocotyls and inner leaves. No anthocyanin was found in the white-leaved phenotype cultivar. Anthocyanin content increased as leaf colour deepened from pink, red, to purple cultivars, which had little chlorophyll and carotenoid. The authors identified eight anthocyanins in the four coloured cultivars, including one non-acylated, four monoacylated, and three diacylated cyanidin glycosides. Cyanidin-3-(sinapoyl)(feruloyl)-diglucoside-5-glucoside was the most abundant anthocyanin in the four coloured cultivars followed by cyanidin-3-(sinapoyl)-diglucoside-5-glucoside. The analysis of anthocyanin accumulation characterisation provides important information on evaluating colouration patterns in coloured plants, and will be helpful for breeding desired leaf colours in ornamental kale. 相似文献

Effects of fruit bagging on coloring and related physiology,and qualities of red Chinese sand pears during fruit maturation 总被引：1，自引：0，他引：1

Red Chinese sand pears (Pyrus pyrifolia Nakai) are particular to China. In order to determine the effects of fruit bagging treatments (including bag types, bag removal patterns and dates) on fruit qualities and to understand the mechanism of coloring of red Chinese sand pears, two experiments were carried out. In the first experiment, fruit of ‘Meirensu’ were firstly covered by light-impermeable paper bags with different levels of light permeable liners during their early development stage, then, the whole bag were/not removed or only the outer layer of bags were removed 3, 2 or 1 weeks before harvest. Thus, the fruit were/not totally re-exposed or were under different levels of sunlight transmission (80.31% or 34.71%). Non-bagged fruit were used as the control. Bagging treatments significantly affected the concentration of anthocyanin and the visual qualities of pear fruit. Compared to control, fruit re-exposed totally for 2 or 3 weeks accumulated the largest amount of anthocyanin and fruit receiving 80.31% and 34.71% of sunlight for 1–3 weeks could synthesize a little anthocyanin, indicating that high light intensity is imperative for coloring in red Chinese sand pears. Bagging treatments did not affect contents of total soluble sugars, but decreased organic acids contents in fruit. In the second experiment, fruit of ‘Meirensu’ and ‘Yunhongli No. 1’ were covered with only one type of light-impermeable bag during the early development stage and totally re-exposed after the bag removal 15 days before harvest. Fruit were then collected at different intervals to trace the time-course of coloring, and related physiology and inner qualities. With increasing time after the bag removal, the concentration of chlorophyll, carotenoid, flavonoid and total phenols changed little, but the concentration of anthocyanin accumulated extremely fast within 10 days after the bag removal in both cultivars and thereafter kept constant. ‘Yunhongli No. 1’ had higher anthocyanin contents and lower hue angle than ‘Meirensu’, indicating a higher potential of anthocyanin synthesis. After the bag removal, the sucrose contents and PAL activities increased gradually and correlation analysis revealed that they were highly correlated with anthocyanin accumulation in two cultivars. This study suggests that anthocyanin biosynthesis in red Chinese sand pears is a highly light dependent process and modified by genotypes. Based on the current results, in order to obtain red Chinese sand pear fruit with attractive appearance and good inner qualities, fruit must be covered with light-impermeable bags at the early stage of fruit development and the bag should be removed totally at least 10 days before harvest. 相似文献

遮光对沪油018油桃果皮花色苷含量及果实着色的影响 总被引：7，自引：2，他引：5
以沪油018为试材,在果实硬核期进行套袋遮光处理,以不套袋果为对照,探讨遮光对果皮花色苷、叶绿素、类胡萝卜素和类黄酮等色素含量及果实颜色的影响。结果表明,套袋遮光处理后20d,果皮中花色苷含量迅速下降并接近于0,此后一直保持较低的水平,直到果实成熟时略有回升其含量仅为对照的2%;同时,套袋处理也降低了果皮中的叶绿素、类胡萝卜素和类黄酮含量,果实成熟时果皮叶绿素含量、类胡萝卜素含量和类黄酮含量分别降低到对照的63.59%、46%和66%。套袋通过改变果实的底色与着色来改变果实的颜色,使果实成熟时的颜色为橘黄色而不同于对照果呈现的浓红色。 相似文献

根域限制对巨玫瑰葡萄果实外观、色素及内在品质的影响 总被引：5，自引：0，他引：5
针对巨玫瑰葡萄在浙江存在的着色差、品质下降等问题对其进行了根域限制栽培试验。结果表明根域限制栽培可以明显改善果实着色,增加果皮花青苷、类胡萝卜素、类黄酮和总酚质量分数,使着色后期叶绿素质量分数有所下降。与花青苷合成相关的PAL酶(苯丙氨酸解氨酶)活性也明显升高。根域限制提高了果肉中的葡萄糖、果糖和蔗糖3种可溶性糖的质量分数;虽然对果肉中的苹果酸影响不大,但是降低了酒石酸的质量分数。另外,根域限制还显著提高了果皮、果肉和种子中白藜芦醇的质量分数。因此,根域限制栽培不仅改善了巨玫瑰的果实外观,而且提高了果实的内在品质。 相似文献

红肉桃果实发育过程中色素和糖酸含量的变化 总被引：5，自引：0，他引：5
以红肉、白肉和黄肉3种不同果肉颜色的12份桃品种为材料分析成熟时果肉中花色苷的含量变化,结果表明,红肉桃与白肉、黄肉品种间花色苷含量差异显著,且红肉桃品种间的花色苷含量差异也很大。利用3个不同果肉颜色的桃品种进一步研究果实发育过程中色素及其相关物质的变化,结果表明,红肉桃品种天津水蜜在盛花后25d果肉中花色苷含量较高,而后逐渐减少;直至进入盛花后45d才缓慢回升,并在果实发育后期(盛花后86d)含量迅速增加;与此对应,该品种果皮在幼果期(盛花后35～45d)和果实发育后期(盛花后86d)2次出现红色,但果肉直到盛花后86d才明显变红;在整个果实发育过程中,天津水蜜果肉其它内含物的变化与白肉桃品种豫白和黄肉桃品种NJC83相似:叶绿素含量逐渐减少;类胡萝卜素和可溶性糖不断增加;可滴定酸前期上下波动变化,但近成熟时天津水蜜的可滴定酸显著高于其它2个品种。 相似文献
