Purpose
This unit standard is for people working in horticulture. People credited with
this unit standard are able to: identify reasons for use of plant growth
modification; modify plant growth using environment controls, and document
results; modify plant growth using applied materials; and define applications
and methods of genetic plant growth modification.

Elements and performance criteria
Element 1
Identify reasons for use of plant growth modification.
Performance criteria
1.1
Physiological reasons for adoption of plant growth modification practices are
listed.
Range
1.2
pest susceptibility, disease susceptibility, lack of plant ability to
meet defined growth requirements, produce requirements.
Economic and commercial reasons for adoption of plant growth modification
practices are listed.
Range
out of season flowering and fruiting, early or late in season
flowering and fruiting, characteristics required by the market,
flexibility and management of multi-crop harvest schedules.
Element 2
Modify plant growth using environment controls, and document results.
Performance criteria
2.1
Environmental characteristics are adjusted to create environmental changes to
modify plant growth.
Range
light, temperature, air circulation and composition, available water.
2.2
Information obtained from monitoring of environmental changes and plant
response is documented.
2.3
Documented results are compared with required plant performance targets, and
adjustments made to the growing environment redress deviation from target
performance.
Element 3
Modify plant growth using applied materials.
Performance criteria
3.1
Materials which change plant growth patterns are identified, and the
characteristics of changes produced by each material are listed.
Range
hormones, nutrients, water, growth regulators.

3.2
Procedures adopted in the application of growth modifying materials conform
with the requirements of the Health and Safety in Employment Act 1992.
3.3
Outcomes achieved through application of plant growth modification materials
are monitored, and action is taken to redress deviation from set performance
targets.
Element 4
Define applications and methods of genetic plant growth modification.
Performance criteria
4.1
Reasons for use of genetic plant modification are identified.
Range
4.2
Major methods of genetic plant modification are identified, and the procedures
used for each method are outlined.
Range
4.3
removal of genetic weaknesses, transfer of genetic strengths from
other plant sources, development of characteristics to make
aesthetic changes sought by markets.
plant evaluation and selection, hybridisation, genetic engineering.
Current and likely future applications of genetic growth modification are
identified for a defined horticulture sector.
Range
horticulture sectors may include but are not limited to – floriculture,
fruit, nursery, vegetable, and viticulture.
Please note
Providers must be accredited by the Qualifications Authority, or an inter-institutional body
with delegated authority for quality assurance, before they can report credits from
assessment against unit standards or deliver courses of study leading to that assessment.
Industry Training Organisations must be accredited by the Qualifications Authority before
they can register credits from assessment against unit standards.
Accredited providers and Industry Training Organisations assessing against unit standards
must engage with the moderation system that applies to those standards.
Accreditation requirements and an outline of the moderation system that applies to this
standard are outlined in the Accreditation and Moderation Action Plan (AMAP). The
AMAP also includes useful information about special requirements for organisations
wishing to develop education and training programmes, such as minimum qualifications for
tutors and assessors, and special resource requirements.
