花的颜色是生物学和商业上的重要特征，基于四种天然色素类黄酮、类胡萝卜素、甜菜色素和叶绿素。温度、光照、营养--以及在保护水中添加糖、盐或金属--都对色素沉着有影响。以4种亚洲百合（Lilium x elegans Thunb.）冬季和夏季的品种。通过计算标准CIE L*A*B* 坐标和色差（E）的便携式分光色度计评估花被片的颜色。在两个季节的叶处理后，具有高红色成分的花的品种（例如紫色的'Fangio'和粉红色的'Brindisi'）在颜色质量上表现出显着的改善。橙色花的'Tresor'表现出改善，只有当K-硫酸盐和混合物（K-硫酸盐和蔗糖）溶液处理，在夏季。黄花的“梅诺卡岛”没有受到影响的处理在夏季或冬季强迫季节。特别是在冬季，观察到所有品种的切花花败育显着减少。在夏季，只有'Fangio'和'Tresor'表现出减少花败育。此外，花的大小和寿命提高了叶处理。从商业苗圃操作中获得的结果表明，百合种植者可以采用非常简单和廉价的处理来改善其产品的重要质量性状。(C)2010 Elsevier B.

Flower color, an important feature biologically and commercially, is based on four natural pigments flavonoids, carotenoids, betalains and chlorophylls. Temperature, light, nutrition - as well as additions of sugar, salt, or metals to the conservation water - have an effect on pigmentation. We investigated the effects of K-sulphate and/or sucrose on flower color in leaf treatments applied 30-10 days before harvest to four Asiatic lily (Lilium x elegans Thunb.) cultivars during the winter and summer. Colors of tepals were evaluated by a portable spectrocolorimeter that calculates the standard CIE L*A*b* coordinates and the color differences (E). After leaf treatments during both seasons, cultivars with flowers with high red components (e.g. the purple 'Fangio' and the pink 'Brindisi') showed significant improvements in color quality. The orange-flowered 'Tresor' showed improvement only if K-sulphate and Mix (K-sulphate and sucrose) solution treatments were applied during the summer. The yellow-flowered 'Menorca' was not affected by treatments during either summer or winter forcing season. Especially in the winter, a significant reduction in flower abortion was observed for cut flowers of all cultivars. In summer only 'Fangio' and 'Tresor' showed a reduction in flower abortion. Also, flower size and longevity were improved by the leaf treatment. The results, obtained from a commercial nursery operation, demonstrate that lily growers can adopt a very simple and inexpensive treatment to improve important qualitative traits of their product.
