I was collecting some pollen on a Nepenthes truncata and was examining the flower stalk when I noticed some peculiar color alterations. The color alteration I am referring to occurred on the flower stalk of the raceme is very abrupt and distinctive. At first I thought that an area of the flower was receiving more light but this was not the case as the immediate flower over lacks complete red pigment. Then I thought maybe that it was an indication of flower age but I found both colors on various stages of flower development. Is this a case of gene expression at work (anthocyanins) or something else? Sorry for the poor quality pictures, I was unable to get decent macro shots with my phone.
Edit: The pictures aren't loading for some reason so here are the links:
As I posted elsewhere, I am guessing it is some sort of signal to attract whatever the native pollen vectors are in the wild, highlighting ripe anthers.
As an aside, Nepenthes do not have anthocyanins. Being members of the order Caryophyllales, the red and yellow pigments of Nepenthes are Betalains (Betacyanins and Betaxanthins, respectively). Betalains have also been found in Drosera, and I suspect they are present in Dionaea as well. These pigments are of taxonomic significance and is one of the molecular links between Nepenthes and other plants such as cacti and the common beet (Beta vulgaris being the namesake of these pigments). Anthocyanins have not yet been found in plants with Betalains.
wow, I did not know that neps takes years to develop a flower..... can I ask something?? what is the maximum pitcher size and pitcher counts does a N.dyeriana and N.miranda can achieve??
No real answer, depends on your condition, for mine, my dyeriana seems to have at least 3 pitchers alive and then by the time the 4th pitcher is on its way, the oldest will start to die. Same for miranda. Of course if you keep feeding your pitchers then pitcher life will shorten. For pitcher size, 25cm is not impossible, still depends on how healthy and the condition your plant is in.

I am also planning to hybridize nepenthes in the future. My main aim is to have a nepenthes that will be resistant to some diseases. I've acquired some useful books that will genetically enhance a plant.

Nepenthes do have a fairly strong immune system already... Although there are some fungi, insects and mites that readily attack nepenthes or only in certain situations, like when the plant becomes stressed.
These are some really bad companies, all shells of Plantron Inc., so don't order from them unless you want small and dead plants they don't want to refund:
Farmer Seed and Nursery
Four Seasons Nursery
House of Wesley
Richard Owen Nursery
How do garbage companies like these stay in business, ripping people off year
thatoneplantboi: Hey guys, I'm new to growing nepenthes, I'm getting a mini indoor greenhouse to grow them in. What kind of light should I use for them? Also, if you could provide a link to a product, it would be very much appreciated

borneo: Yes, they work superbly. But you don't need expensive lights, cheap ones work well too.

etiennecancio: perhaps we can try to revitalize the old forums? i always found them to be much more convenient than facebook groups at least hah

vidyut: hey mylesg. glad to hear that. Love this forum. Facebook can't organize knowledge like this. Will participate as much as I can.

vidyut: Photobucket has ruined this place and many other forum archives with years and years of photos worth referencing now blurred. Priceless information hostage to services once free, begging for adoption, arbitrarily monetized.
