Does nectar chemistry act as a filter and drive the community composition of nectar microbes? Check out our preprint "Nectar compounds impact bacterial and fungal growth and shift community dynamics in a nectar analog" with @rachelvannette& @J_S_Francis! https://t.co/HYAlAHvJMW
Luv this beautiful picture of Josh O. getting some nature healing, smelling azaleas in the Spring Show. Some of the offspring of the azalea plants at GPC hail back to the 1893 World’s Fair that took place in Chicago! #Persevere
Here are some azaleas u can see in the show. 🌸🌼
Started bloomin from the bottom now we’re here. Guien is about done flowering. The blooms started at the bottom of the stalk & move slowly to the top. After this it’ll be a several week process of slowly saying good bye. Her leaves are collapsing & she’s getting wrinkles. (1/2)
Epic news on Guien: She flowerin'! Last Tuesday on 1/25/22 she began the flowering process which starts at the bottom & proceeds slowly to the top of the quiote (flowering stalk). On Tuesday 2/1/22 she measured 20 ft 1 in! She is flowering w/beauty this Black History Month.
The flower starts off producing a yellow nectar that has a pH~6 and it turns red within a couple of hours due to alkalinization (pH~9). The nectars displayed differences in spectral properties and LC-MS/MS analysis revealed that the pigment was an imine conjugate of proline and
The true pollinator of Nesocodon flowers is unknown, but several Mauritian species produce colored nectars and are visited and pollinated by day geckos. We wanted to crack the enigma of the red nectar and whether it would attract day geckos (Phelsuma)
