Excerpt From The Course

STAGES OF FLOWER BUD GROWTH

The stages from shoot to flowering can be broken into the following stages.

 

  1. Induction: biochemical changes that cause the vegetative bud to become reproductive
  2. Initiation: can be defined as the time that the plant is committed to bud development
  3. Differentiation: during this stage the individual parts of the flower form
  4. Development: growth of the flower parts
  5. Anthesis: the opening of the flowers

 

As mentioned in Lesson 1 shoots must progress past the juvenile phase into the (adult) vegetative phase and then on to the flowering phase.  The key point here is that seedlings cannot be induced to flower, the plant must have passed on to the adult phase in order to develop flowers.  

 

In order for the plant to be ready for flowering the apical meristem switches from vegetative to reproductive, this is known as induction. At this stage the plant is then susceptible to environmental variables that may induce flowering.  Once the apex has become a flower primordia the process is irreversible. The bud development cannot be reversed, however if conditions are unsuitable the bud may abort and the auxiliary buds will resume vegetative growth.

 

Examples of what can affect Flower Bud Initiation

Scientists have found many different things can affect the formation of flower buds, to a greater or lesser degree. Many of these factors may affect some types of plants and not others. Many of these factors interact with each other, sometimes in a positive way, and sometimes in a negative way. The following are a range of examples that can play a part in the stimulation of flower initiation:

 

  • Exposing apples to ammonium ions can cause more axillary buds to form on the main stem. (Duration of exposure appears unimportant with 1 day giving the same result as many weeks.
  • Dormant tulip bulbs took less days from planting to flowering when exposed to higher than normal levels of ethylene, and stored for a period at higher temperatures (20 degrees C)
  • The temperature during flower bud initiation affects the development of orchid buds into a flower.
  • The time for flower initiation in Freesias is affected by the average of soil and air temperatures. If soil and/or air temperature is increased, flowering is delayed. At 21 degrees C, the plant can remain vegetative.
  • Water levels during the day can affect flower initiation in tropical Carambola trees (Averrhoa carambola) by as much as 10%.
  • Flower initiation in Azaleas is an interaction between temperature and light. At 15 degrees celsius, Azaleas are day neutral, but at 20 degrees Celsius they are short day plants.
  • Annuals, Biennials & Perennials all appear to have the same mechanisms for flower initiation. Once the plant reaches maturity, vegetative meristem tissue is converted to floral tissue capable of producing flowers.

 

Differentiation requires N (nitrogen) and CHO from photosynthesis; it is also sensitive to temperature and shade effects.

 

Development

Development of the flower buds at a successful rate and quality can be affected by the following:

 

  • Water availability
  • Temperature changes
  • Nutrient deficiencies
  • Defoliation
  • Injury
  • And inadequate chilling during dormancy for some plants

 

Anthesis

Conditions affecting the duration of anthesis have direct implication to cut flower harvesting and post harvest storage.  Additionally the stage of development or anthesis at which flowers are harvested can have impact upon their storage life.  Generally flowers harvested later in to their development will have a shorter shelf life.  The best stage to harvest flowers will depend upon many factors including the species, cultivar, and the market requirements.  It is of course possible to harvest flowers before anthesis due to the existence of special techniques which allow.

Previous Customer Experiences with our Courses

"Fantastic Teacher. Well organised modules. Assignments force me to learn and research more so I can prepare well for exams. I really enjoyed studying via ADL.  I can now continue study at Ulster University which accept my certificate from ADL".    Level 4,  Advanced Certificate in Applied Science,  VSC001,  Stanislawa,  Poland.

Its with great pleasure I am announcing you my new job as 'Park Manager' for a 5 star hotel in Reunion Island.  Its definitely my courses with ADL (Botany, Agronomy and Tree for Rehabilitation) which were decisive for my nomination. Accordingly, my sincere thanks goes to all the ADL team.

"The course was a valuable learning experience as it provided me with the knowledge and understanding for me as a Careers Advisor. The feedback was very good from my tutor, and allowed me to  build upon my assignments that were marked. The comments were very informative  and very useful. Well written course material."  Andrew W, Careers  Counselling, UK

"It exceeded my expectations. It was more comprehensive than I expected and the assignments really stimulated deep study of the subject. Thank you for your guidance. I am delighted with my certificate and will recommend this course and ADL to my friends and colleagues."  G Flaherty, Ornithology BEN102, Ireland

"I want to thank you for  the course - Hotel Management- I've just finished now. The course was comprehensive and well edited. For sure it can give a new worker in the hospitality industry the basic theoretical and practical knowledge required".  Daniel K, Hotel Management, Romania

"Upon completing the Interior Plants Course I was offered my dream job.  Taking this class was one of the best decisions I've made, the information I received was invaluable.  Thank you ADL". Meg V,  Interior Plants, Florida, USA.

“I am delighted to report that I passed the exam and received a “Pass with Commendation”. I appreciate very much the detail that you went into, in the correction of my assignments  and I found your advice and extra subject information  invaluable in advancing my interest and knowledge in horticulture”.   Go raibh mile maith agat! (a thousand thanks!) Colin, RHS Cert II, Ireland

"Although my main interest in Earth Science is Geology I found this course excellent. The course notes were very interesting and useful throughout the course. Thank you to the ADL staff for their excellent service" Barry. Earth Science

"I received good feedback, and had an efficient turnaround of assignments, useful comments and grades to analyse." Andrew, Calf Rearing

"I enjoyed the course and developed a good understanding of learning and behaviour disorders. I feel this will be helpful in my role as a Clerk at a local primary school". The course met my expectations and I enjoyed the challenge of learning about conditions i knew little about. The presentation of the course and the opportunity to communicate with my tutor was valuable. I enjoyed the course so much , I am planning to do another! Jennifer C, Developmental Learning and Behavioural Disorders in Children and Adolescents, UK
