Mutation breeding is one of the most important method for ornamental plants. Chrysanthemum genus that has richest mutant varieties in The objective this study to create variation by gamma irradiation and improving traits mutation breeding. For aim, vitro bud explants white Bacardi variety were irradiated radiation at 20 Gy (Gray). In subcultures continued until M1V4 period observations obtained...

Nudicaulins are a group of indole alkaloid glycosides responsible for the color of yellow petals of Papaver nudicaule (Iceland poppy). The unique aglycone scaffold of these alkaloids attracted our interest as one of the most unusual flavonoid-indole hybrid structures that occur in nature. Stable isotope labeling experiments with sliced petals identified free indole, but not tryptamine or l-tryp...

Editorial/Commentary DPC | Dermatol Pract Concept 2013;4(2):10 51 In this issue, Rosendahl and colleagues report a case of non-choroidal melanoma that shows a strikingly unusual dermatoscopic aspect, namely, structureless yellow color. The authors correlate the yellow color to the presence of lipofuscin using tissue staining with Sudan Black. Upon dermatoscopy, colors are important because they...

Flowers and fruits are often vividly colored. An obvious explanation for fruit and flower pigmentation is that it serves to attract animal mutualists. However, decades of research has produced equivocal support for the hypothesis that animals are the primary selection pressure acting on the color of plant reproductive structures. Exciting new research into geographic variation in flower colors ...

Even though pigmentation traits have had substantial impacts on the field of animal evolutionary developmental biology, they have played only relatively minor roles in plant evo-devo. This is surprising given the often direct connection between flower color and fitness variation mediated through the effects of pollinators. At the same time, ecological and evolutionary genetic studies have utili...

Model calculations are used to find an optimal color vision system for the coding of natural objects. The criteria to assess the quality of color vision are (a) discriminability between all colors of a given set; (b) discriminability between nearest neighbors (only the most similar colors of a set); and (c) detectability (color difference between target and background). The colored objects inve...

To clarify the influence of yellow, green, and proportional yellow-green light on capture effect, western flower thrips, Frankliniella occidentalis (Pergande), were captured using different self-made sources in a greenhouse. The bio-activity effect thrips was regulated by analyzed to determine reasons for changes their light. results showed that thrips’ induced with same brightness positively c...

There is a large literature focused on the color perception of matte surface. However, recent research showed that the component of surface specular reflection, such as glossiness, also affects categorical color perception. For instance, the color term "gold" was used to name high specular stimuli within a specific range of chromaticity, which overlaps with those of yellow and orange for low sp...

Research on honey is important from the standpoint of product quality and consumer protection. According to legislation in many countries, including Ukraine, considered a food subject mandatory certification labeling. physicochemical properties for determining its detecting falsification. This article dedicated study various botanical one regional source. Organoleptic were determined, as well c...
