Why are growth retardants used in the greenhouse industry?
Plant growth regulators (PGRs) applied to greenhouse crops can suppress or promote growth, increase branching, or promote or delay flowering. To produce high-quality compact flowering plants proportional to container size, growers can use non-chemical and chemical methods.
What do you do in floriculture in FFA?
The Floriculture Career Development Event (CDE) requires students to identify plants, judge flower arrangements and solve problems. Participants also demonstrate skills in flower arranging, propagation and the preparation of floral and foliage products for sale.
What are the types of growing media used in floriculture production?
- Peat and Peat-Like Materials. Peat moss is formed by the accumulation of plant materials in poorly drained areas.
- Wood Residues. Wood residues constitute a significant source of soilless growing media.
- Rice Hulls.
- Calcined Clays.
What are the best ways to regulate plant growth?
Physical control options include container size, timing, water stress, nutrient stress, mechanical conditioning, spacing, light quality and quantity, pinching and temperature. Restricting roots can also control plant growth. This is done by using a smaller container or a higher number of plants per pot.
How are growth retardants commercially useful?
As growth retardants, these compounds are used commercially in agriculture and horticulture industries. For instance, chlormequat and mepiquat chloride are used as antilodging agents in cereal crops and to reduce excessive vegetative growth in cotton.
What is the purpose of floriculture?
Floriculture, or flower farming, is a discipline of horticulture concerned with the cultivation of flowering and ornamental plants for gardens and for the floral industry. Floriculture crops include bedding plants, flowering plants, foliage plants or houseplants, cut cultivated greens, and cut flowers.
What is soilless growing media?
As its name suggests, a soilless medium is any sterile medium for growing plants that doesn’t involve soil. There are soilless media made from organic and inorganic materials. These materials are often used with fertilizers, which ensure plants receive all the nutrients they need to thrive.
What is an advantage of a soilless mix?
A soilless mix provides a cleaner medium and gives you more control. 1 Besides being free of pests and diseases and other contaminants, you can blend in additional ingredients for preferred drainage, water retention, nutrition, and airspace.
What are the controls in growing plants?
The factors that control plant growth behaviour in response to PGRs include the type of plant, type of stimulant, amount of stimulant applied, timing of application, stage of growth, and location of stimulant application (Mitchell, 1942).
Why are growth regulators used with bedding plants?
Growth Retardants for Bedding Plants Plant growth regulators are most effective when applied at the appropriate times to regulate plant growth or development. Growth retardants cannot shrink an overgrown plants. They must be applied before the plant is overgrown to prevent plant stretch.
