Mobile Plant Analysis Lab @ pifCamp, Slovenia
This is part of the ongoing work during pifCamp on my Lab-in-the-Wild
DIY sap press
just use a garlic press :-)
What the heck is a "petiole"?
"In botany, the petiole is the stalk that attaches the leaf blade to the stem. The petiole is the transition between the stem and the leaf blade."
Most Common Methdos
Near Infrared Photography
as usual the people from publiclab have already done a great job!
A great use of our spectroscopes!
Atomic Absorbtion Spectroscopy
Quick Nitrate-N Tests
Simple Cholorophyl extraction methods:
Hmmmm, checking the MultispeQ again
Protein Content Colorimetric Assays
This link helped me a lot:
There are quite a few out there. The Biuret test, testing peptide bonds with some copper-ions, and it's modifications the BCA and Lowry tests. most suitable for our first experiments seems to be the Bradford assay with it's color change from brown to blue.
- Bradford Reagent from Sigma Aldrich
- Other more expensive kits
- still need a standard sample. but i got some BSA somewhere....
Literature and Links
Handbook of Methods for Plant Analysis
Plant analyses are usually carried out on prepared samples in a laboratory under controlled conditions. Testing of forage samples may be conducted with near infrared spectrometry (NIR) in mobile laboratories. Plant tissue tests or quick tests can be conducted in the field on living plant tissue, plant sap, or fluid.
Not so sure about that...
