| Beech trees have more of a red pigment called anthocyanin and birch trees have more carotene which turns leaves yellow. |
|
| He has pinpointed markers signaling the presence of an unwanted, purplish color in wheatgrasses caused by the pigment anthocyanin. |
|
| In many other trees such as black gum, sassafras, dogwood, and some maples and oaks, the pigment anthocyanin adds red to the palette. |
|
| The colour itself is anthocyanin, basically the same pigmentation as people can see in the autumn. |
|
| An example is the black raspberry, which has the highest anthocyanin level of any temperate fruit. |
|
| Some modifiers have been reported to enhance anthocyanin pigmentation of vegetative parts in plants carrying specific r1 haplotypes. |
|
| Pigment accumulated throughout the shaft of the silks and was not limited to the silk hairs as is typical of anthocyanin pigmentation. |
|
| The fruit also has anthocyanin, which may inhibit cholesterol formation, and ellagic acid, which may block the initiation stage of cancer. |
|
| Antioxidant activity, total phenolics and anthocyanin levels were strongly correlated with one another. |
|
| The characteristic should be observed as the proportion of the total length of main veins with anthocyanin coloration. |
|
| For example, in pea, marbling and anthocyanin spotting of the testa should be separated. |
|
| Leaf rib anthocyanin was measured only in FR, where one QTL was detected. |
|
| The anthocyanin coloration of the internode should be observed between the third and fourth node above the ground. |
|
| Some of these sugars are converted to anthocyanin, which has a purple colour. |
|
| In varieties with plant anthocyanin present, the testa will contain tannins which vary in color from reddish brown to brown to brownish green. |
|
| A typical anthocyanin is red in acid, violet in neutral, and blue in alkaline solution. |
|
| Within two or three days all seedlings of varieties with anthocyanin will show this characteristic. |
|
| On closer examination some green skinned varieties have light anthocyanin, uniformly expressed, and should be classified as bronze skinned roots. |
|
| But the reason for youthful blushing which, like the ruddiness of old age, is due to the presence of anthocyanin pigments need not be the same. |
|
| Interruptions in the anthocyanin coloration should not be included in that proportion. |
|
|
|
| The mutant also has severely reduced growth rates and a distinctive purple leaf colour as a result of increased anthocyanin pigmentation, particularly when grown in soil. |
|
| The combination of excess sugar sap and sunny days create an abundance of the pigment anthocyanin and the brilliant fall colors of crimson and purple. |
|
| Fresh chokeberries, elderberries, black raspberries, blueberries, and black currants had the highest anthocyanin content among tested foods. |
|
| On day 1, 6 individuals were intravenously injected with normal saline solution at 8 AM, and then administered anthocyanin capsules 30 min later. |
|
| The extracts were fractionated into anthocyanin, neutral, polymeric and oligomeric fractions. |
|
| The study showed that Kansas-bred potato had significantly higher anthocyanin contents compared to the other potatoes. |
|
| Crops with high phenolic and anthocyanin content have bioactive and functional properties as well as the highest antioxidant capacity. Purple Corn has higher antioxidant capacity and antiradical kinetics than blueberries. |
|
| More than one anthocyanin may be present in a flower or blossom, and the colours of many flowers are caused by the presence of both anthocyanins and plastid pigments in the tissues. |
|
| One of the best natural sources of a bioflavonoid called anthocyanin which helps the body build strong veins and fights the effects of premature aging. |
|
| The two snapdragon genes researchers added, however, are master regulators of anthocyanin production: they turn on the genes, normally off in tomatoes, necessary to produce anthocyanins. |
|
| The highest anthocyanin concentration was detected in the free form. |
|
| The anthocyanin coloration should be recorded as present if anthocyanin occurs in one or more of the following: seed, foliage, stem, axil, flower or pod. |
|
| The flavylium cation is the parent of the anthocyanidines, substances that in chemical combination with sugars form the anthocyanin pigments, the common red and blue colouring matters of flowers and fruits. |
|
| The anthocyanin coloration should be observed at stage one or two leaves. |
|
| If the proportion of blue is low the anthocyanin appears red-violet. |
|
| The anthocyanin coloration should be recorded on the stigma from the central third of the head just after the pollen appears at the top of the anthers. |
|
| All observations on the presence or absence of anthocyanin coloration in vegetative organs refer to the general appearance of the organ, irrespective of whether red pigments are present in hairs or in the underlying skin. |
|
| The anthocyanin development in the skin of light beige and yellow skinned varieties should be assessed after 10 days of exposure to full daylight or after 150 hours of exposure to artificial light. |
|
| In fact, recent research links a substance in blueberries, called anthocyanin, not only with blueberries' beautiful indigo colour, but also with possible strengthening of eyesight in certain individuals. |
|
| The dissolved colouring-matters are, in white flowers, antholeucin, in blue anthocyanin. |
|
|
|
| Aronia melanocarpa fruit juice is rich in phenolic antioxidants, especially flavonoids from the anthocyanin subclass. |
|
| Differences may also be found in phyllotaxy, intemode length, anthocyanin pigmentation, rooting ability, or wood structure. |
|
| In this case, the researchers increased the flavonol and anthocyanin content of tomatoes. |
|
| Most carnivorous plants require bright light, and most will look better under such conditions, as this encourages them to synthesise red and purple anthocyanin pigments. |
|
| Blueberry fruits are known as a rich source of anthocyanin components. |
|
| The researchers exposed extracts of anthocyanin pigments from blueberries, chokeberries, black raspberries, red grapes, and strawberries to human saliva. |
|
| Interestingly, it was found that when the flower petal contains lower anthocyanin content, the total chlorophyll content exhibited a higher value relatively. |
|
| Recent scientific research shows that the fruit's juice stops mice piling on weight when fed a high-fat diet, possibly due to its high levels of anthocyanin. |
|
| Earlier work by Stoner's group found that black raspberries contain ample amounts of the two cancer-fighting compounds ellagitannin and anthocyanin. |
|
| In 2005 Japanese scientists reported that iron, magnesium and calcium work together with the plant compounds anthocyanin and flavone to produce the blue of cornflowers. |
|
| In other parts of the world, the leaves of deciduous trees simply fall off without turning the bright colors produced from the accumulation of anthocyanin pigments. |
|
| Anthocyanin pigments produce red and purple colors, though they are not always present in the leaves. |
