Pollen Collection Methods for Research - Need Advice for Smaller Flowers
Hi all, I’m a graduate researcher working on bee-plant interactions and need to collect ~10 mg of pollen per flower species from the three most abundant species at my field site.
So far, I’ve experimented with a few approaches:
•Anther collection + processing: Collected anthers and tried vortexing and centrifuging, but results were inconsistent and yielded less pollen than expected
•In-field brush collection: Using paint brushes has been the most reliable so far, but it’s incredibly time-consuming, especially for tiny flowers like Amsinckia
The brush method works, but as a grad student on a tight timeline (and tighter budget), I’m looking for something more efficient.
My questions:
•Has anyone optimized pollen collection for small-flowered species?
•Are there better processing methods for anthers that actually yield decent quantities- such as drying?
•Any tricks for speeding up brush collection?
I’m open to whatever works and low-tech solutions are totally fine! Any suggestions appreciated. Thank you for your time :D
Poison oak, beware
Toxicodendron diversilobum contains compounds called urushiola which can cause severe itching, so know before you go. Here, flower buds are evident as small yellowish balls. Washington state, USA on April 9.
Levantamento sobre Desafios na Agronomia e Uso de Tecnologias no Campo
Olá bom dia. Me chamo João, moro em Mogi Guaçu SP, estudo em uma Etec da minha cidade. Estou no último ano do ensino médio e estou desenvolvendo um TCC, nesse projeto eu abordo um tema de prevenção de doenças em plantas com o uso de IA. Gostaria muito que vocês pudessem responder um questionário, ele será de extrema importância para mim. São 15 perguntas bem simples. Agradeço.
Are all lithophytes saxicoline? Are all saxicoline plants (obligate or facultative) lithophytes?
Been confused about this for a while
Does tree pollen biologically trigger other species of plants to bloom?
Hi, I was hiking yesterday in Portland, OR and we are currently experiencing our yearly mega pollen event where everything is covered in fine yellow powder. I had the thought that tree pollen, would be an amazing mechanic to signal to much less hearty plants, that spring time is a “go.”
Is this a thing? Seems like it would be such a powerful chemical signal in the timing of plant growth. TIA!
