Role of anthocyanin in Sarracenia

[frenchy87128]

I had been meaning to get these posted sooner than later on here per Phil's request but better late than never right? ;D

I made the trip up to Meadowview for my Spring Break to get my Master's thesis experiment setup which will attempt to look at anthocyanin in Sarracenia leucophylla and it's role on capture rates.
After numerous divisions of F2 hybrids (leucos and antho free leucos) 60 divisions of comparable size were potted up. Not pictured are another 3 plots of 20 pots. I'll be making the trip back in October to collect the pitchers and start the task of analyzing their contents.
Big thanks to Phil for allowing me to set this up at Meadowview using Meadowview materials and all the volunteers that helped out with helping me put this together!

Isn't research great! Thanks for sharing the photos - I look forward to hearing more as your research develops.

Perhaps you'd even be up for writing up something for the Carnivorous Plant Newsletter!

Thank you Michael,

I would be delighted to put something together for CPN. Just give me another year to complete the study =D

You betcha -- Can do! :-)

in all the plant the ecophysiological role of anthocyanin seem when you read some documents

some effect in :a expanding and senescing leaves,nutrient deficiency ,UV light , herbivory and pathogen infection .

and also a hypothesis from a photoprotective role :antioxidant, its distribution in leaves,and its synthesis in seedlings .

the PH seem also to have a great role in the anthocyanin color.

Hi Jeff,

I would certainly agree with you that pH and nutrient deficiencies play a large role with anthocyanins. Here are a few articles regarding the topic.

You can experiment with pH and anthocyanins by soaking blackberries in water until the water is black. The higher you make the pH the lighter the water will become.

an others experiment spectacular with the hydrangea flower .

to have a blue hydrangea ,then that they are pink,use a substrat with a acid PH

very good document on the UV role ,

NB:in the vegetal cell , the anthocyanins are in the vacuole .

for the red leaves , the carotene also is involve , by the chloroplaste
