“维基basics of blue flower colouration词条下有讲双色异味的引入确实导致了玫瑰苷的生产,所以异味血统重的和平后代常出现蓝紫色。并且说在偏向香气的演化过程中玫瑰苷被各原种淘汰。

In the early 1900s, a new species of rose called Rosa foetida 'bicolor' was introduced into world commerce from the middle east. It has flowers which are bright shades of butter yellow, orange, and velvety blood red, which introduced new genetic traits that serendipitously and coincidentally created a pathway toward new lavender and blue pigments that are independent of delphinidin, a blue pigment not naturally found in roses.[citation needed]
That pathway involves the final stages of flavanoid pigment synthesis which would normally cause flowers to appear yellow or orange. This new species carried small traces of unused genes that allowed production of another type of blue pigment called rosacyanin, which most roses evolved to stop utilizing in favor of producing flower fragrances to attract pollinators.[citation needed]
Rosacyanin allows roses to come in delicate mauve, lavender, and true blue shades.[citation needed]
These colors can be seen in the hybrid tea roses 'Sterling Silver', 'Blue Girl', and 'Blue Moon', among others, which descend from yellow roses. Most notably a popular yellow hybrid tea rose called 'Peace', which was named to commemorate the end of World War II, was used extensively in hybridizing, and fathered most of the original lavender hybrid teas.[citation needed]
Rosacyanin B is composed of cyanidin and gallic acid. 玫瑰苷是矢车菊素和鞣酸结合的产物
The two pigments in 'Sterling Silver', Rosacyanin A1 and Rosacyanin A2, are Rosacyanin B connected to different ellagitannins.
