Collection of fresh pollen from smaller flowers such as canola.

  1. Collect flower clusters in the early morning when plants are 40-50% flowering.
  2. Place the clusters into containers.
  3. Allow the clusters to dry at a processing location.
  4. Brush flowers over food strainers to separate pollen from anthers.
  5. Clean samples of pollen by sifting through multiple sieves of different pore sizes (pore sizes 0.119 and 0.0043 cm).
  6. Store collected pollen at -20°C until ready for further testing.


- Above mentioned methods allow for the relatively easy collection of a large amount of pollen.

- Allow for the collection of pollen of single and known plant origin.


-  Methods such as the paint brush collection method is very time consuming and requires a large number of flowers (up to 30,000 in the case of aloes, see Human and Nicolson, 2006) to enable one to collect enough pollen.

- Sieving samples of pollen to clean all debris from collected pollen is time consuming.

- Working with large amounts of fresh pollen can be detrimental to health and increase allergies.
