The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

What evidence can you provide to prove your understanding of each of the following citeria?
Prepare replicates for testing
|
|
Pure Seed is mixed thoroughly to reduce bias in results. Completed |
Evidence:
|
Prescribed number of replicates are drawn from the Pure Seed fraction according to enterprise guidelines. Completed |
Evidence:
|
Safe work practices and personal protective equipment are used to ensure personal safety and that of other laboratory personnel. Completed |
Evidence:
|
Pre-moisten replicates
|
|
Seed is pre-moistened to reduce possibility of injury to seeds when puncturing or cutting and to enable penetration of the tetrazolium solution under prescribed temperature and light conditions. Completed |
Evidence:
|
Sticky mucilage is removed from seeds as necessary. Completed |
Evidence:
|
Seed tissue is exposed prior to staining according to enterprise guidelines. Completed |
Evidence:
|
Seeds are kept moist prior to testing. Completed |
Evidence:
|
Stain with tetrazolium solution
|
|
Seeds are completely immersed in tetrazolium solution according to enterprise guidelines. Completed |
Evidence:
|
Fungicides and/or antibiotics may be added to solution according to enterprise guidelines. Completed |
Evidence:
|
Low light levels are maintained as required by testing procedures to facilitate staining. Completed |
Evidence:
|
At completion of staining period, the solution is decanted and seeds are rinsed with water. Completed |
Evidence:
|
Evaluate test results
|
|
Each seed is examined and evaluated as viable or non-viable based on staining patterns applicable to the species being tested. Completed |
Evidence:
|
The number of seeds considered viable in each replicate is counted. Completed |
Evidence:
|
The percentage of viable seed in each replicate is calculated and average percentage of viable seed across all replicates is determined. Completed |
Evidence:
|
Finalise reporting and clean up
|
|
Results of test are recorded and reported according to enterprise guidelines. Completed |
Evidence:
|
Laboratory and hazardous waste are safely handled, collected and disposed of according to enterprise guidelines. Completed |
Evidence:
|
Apparatus and equipment used in tetrazolium test is cleaned and used chemicals and solutions are disposed of safely in accordance with enterprise guidelines. Completed |
Evidence:
