AHCSDT303A
Perform a fluorescence test on seeds

This Unit covers undertaking a test that is designed to determine the presence of annual ryegrass species in perennial ryegrass seedlots.

Application

This Unit applies to seed analysts working independently or under limited supervision, within enterprise guidelines. In general, they prepare samples for testing; conduct specified tests in accordance with enterprise requirements; maintain records and interpret results; and troubleshoot equipment problems.


Prerequisites

Nil.


Elements and Performance Criteria

1. Prepare for a fluorescence test

1.1 Seed to be tested is identified and records completed.

1.2 Working sample is prepared from submitted sample.

1.3 The required number of replicates of 100 seeds are prepared.

1.4 Substrate is prepared with potassium nitrate.

1.5 Replicates are placed in a germination cabinet/room as directed.

2. Assess germinated seeds

2.1 All un-germinated seeds and abnormal seedlings are counted off and the number recorded.

2.2 Normal seedlings are examined under ultra violet light.

2.3 Normal seedlings that have fluorescent roots under ultra violet light are counted off and the number recorded.

2.4 Normal seedlings that do not have fluorescent roots under ultra violet light are counted off and the number recorded.

2.5 Exposure of bare skin to ultra violet light is minimised.

2.6 Enterprise worksheet is completed.

3. Maintain a safe work environment

3.1 Results of test are recorded, calculated and reported in accordance with enterprise guidelines.

3.2 Laboratory and hazardous waste are safely handled, collected and disposed of.

3.3 Apparatus and equipment used are cleaned and used chemicals and solutions are disposed of safely.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this Unit

Evidence of the ability to:

prepare replicates from working sample

assess seedlings using ultra violet light

counting and recording of results.

Context of and specific resources for assessment

Competency requires the application of work practices under work conditions. Selection and use of resources for some worksites may differ due to the regional or enterprise circumstances.

Method of assessment

This Unit should be assessed together with core Units and other Units of Competency relevant to the function or work role.

Guidance information for assessment

To ensure consistency of performance, competency should be demonstrated on more than one occasion over a period of time in order to cover a variety of circumstances, cases and responsibilities, and where possible, over a number of assessment activities.


Range Statement

The range statement relates to the Unit of Competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Seed may include:

bare seed; treated seed; and coated seed that has been prepared as required.
