GROW CUT FLOWERS IN A GREENHOUSE

  • Learn more about greenhouses and how to better manage, light temperature and humidity for plants grown inside
  • Explore and compare the commercial and horticultural differences between different types of flowers
  • Start a business - Be better at your job - Improve your career prospects

A course for commercial cut flower growers who are concerned exclusively with greenhouse production. International trade in cut flowers has grown over recent decades. In most countries, developed or in development, it is now possible to get the most popular types of cut flowers almost any time of the year.

The industry has made this possible by doing three different things:

  1. Expanding trade between countries (e.g. Australian tulips might be flown to the Netherlands in August and September, when they are not flowering in The Netherlands; and Dutch tulips might be flown to Australia when it is autumn in Australia)

  2. Breeding new varieties has extended the flowering season for some plants. It is now, for instance, possible to grow Chrysanthemum varieties that flower all year round in some climates.

  3. Growing in greenhouses has enabled farmers to take control of conditions that stimulate flowering; and cause plants to not only grow faster, but also flower at times when they might not have otherwise flowered.

GETTING PLANTS TO FLOWER OUT OF SEASON

Flowering occurs when there is a sudden change in the growing point, from vegetative organs (i.e.: leaves, stems, leaf buds) to floral organs. When this happens, the apical dominance (i.e. the dominance of the growth in the upper end of stems that inhibits growth of lateral buds) usually weakens.

The initial stimulus to cause this change in tissue type appears to normally originate in the leaves (though not always). Some target cells or tissues are stimulated by a fairly non specific trigger, setting off a chain reaction (cascade) throughout the involved tissue. Much work has been done trying to discover the chemistry of these changes, but the results tend to only show that there is a very great complexity involved

As flowering tends to be related to particular times of the year, the initial stimulus is most obviously environmental. There are three possible types of environmental stimuli:

  • Physical eg: Changes in photoperiod (longer/shorter days), humidity, pressure
  • Electrical e.g: Changes in pH
  • Chemical: Changes in levels of certain chemicals eg: More light increases photosynthesis, which increases levels of sugar in the plant

There are two types of chemicals involved both promoters & inhibitors. The promoters stimulate the process of flower induction. The inhibitors inhibit this inductive process. The promoters and inhibitors do not work together in a balancing interaction. They affect each other through an interference process (eg: With Kalanchoe, short days produce promoters, but if more than one third of the days are long, sufficient inhibitors are produced to stop the effect of the promoters).

JUVENILITY is a completely different thing to the effect of inhibitors. A plant cannot respond to the effect of flowering promoters until tissue has gone through a phase change to reach maturity. It is possible for this phase change to be reversed and mature tissue become juvenile again.

How can I start this course?

You can enrol at anytime and start the course when you are ready. Enrolments are accepted all year - students can commence study at any time. All study is self paced and ACS does not set assignment deadlines.

Students in such situations are advised to check with their sponsor prior to enrolling. The nominal duration of a course is approximately how long a course takes to complete. A course with a nominal duration of 100 hours is expected to take roughly 100 hours of study time to complete. However, this will vary from student to student. Short courses (eg. 100 hrs duration) should be completed within 12 months of enrolment. Certificates, Advanced Certificates and Awards (eg. over 500 hours duration) would normally be completed within 3 -5 years of enrolment. Additional fees may apply if a student requires an extended period to complete.
If a student cannot submit their assignments for 6 months to ACS, they should advise the school to avoid cancellation of their student
registration. Recommencement fees may apply.
