Photosensitive Rose Blooms

Post by Guest on 5th October 2011, 19:19

I am aware this is a common occurrence in China's. I bred this rose a few years ago and has this nice trait which I like. Alot of rose blooms fade, or which happens a lot in reds, turn purply blue. This rose as the days progress turns redder and redder as the red in the lower petals and they last well on the bush for around 5 days. It is (Altissimo x Perfume Delight)

One can only assume it is the 'Altissimo' side doing it.

Dave; not sure about that, but Altissimo doesn't really fade as I can recall. This one starts off like this and then ages to altissimo's red colour, suppose it better than turning blue.

I guess Warren, one of those that turn "purple" is 'Mr Lincoln as the heat gets it.

Warren is it in their breeding or something to do with the pigments.

Sort of both Dave, there are a number different pigments and depending what ratio and concentration give you the colour and some of theses traits are passed on during breeding. Wikipedia has a easy to understand version in what its all about, Google Biological pigments.

I've noticed with [You must be registered and logged in to see this link.] that the pink edging will extend over the petal as the bloom ages. Some blooms end up quite dark pink/scarlet sometimes. Is that the same kind of reaction that you are talking about with your rose?

Cool. Do you think it is highly heritable?
