Re: Re: HYB: Lycopene color(s)


 I have not had time to follow this discussion but from Lindas post i thought i might be able to shed a little light on the contents of the cell. Cell walls are relatively stable and inflexible. The cytoplasm which contains chlorophyll in plastids and many of the carotenes and flavones is a sack inside the cell wall. this sack is pressed up against the cell wall because inside this sack is another sack that takes up most of the cell space. This is the vacuole which contains anthocyanin, the blue/pink pigment depending on PH. So there is a thin layer of cytoplasm around the outside of the cell and this large space with cyanic pigment in the middle. Cells vary and in a petal you may have cells that are mainly vacuole on the surface and one or two different structured cells below. These cell layers can well have entirely different proportions of anthocyanin to carotene/xanthophyll. If you note the undersurface of many tall bearded flowers, the last and fourth layer may be an entirely
 different color than the upper surface. The intensity of color can be affected by each of these layers. The intensity can also be affected by the dispostion of the pigments in each area of the cells. I hope this adds to the understanding even though it shows the complexity.
