Aim of the workshop:

The workshop aim is detecting some quality parameters of wild species and flowers outside of the ISTA Rules and it is focused on the needs of seed testing laboratories that would like to work according to the ISTA Methods, standardizing testing methods for determining viability of seeds and Equilibrium relative humidity (ERH), a new test method, alternative to moisture content, for small seed lots or precious seeds.

Language: English (slides and presentations)

Preliminary Programme

Tetrazolium Test 

- Principle of testing with Tetrazolium salts
- Preparation of a validation method to introduce new species in the Rules
- Practical method developed to test some wild species seeds  

Moisture part

- Principles of Equilibrium relative humidity (Water activity) vs moisture content determination
- Practical determination of ERH vs MOI content determination in some wild species seeds

Flower Seed Testing part

- Testing seeds of flower wild species: general aspects
- Testing seeds of flower wild species: practical works
