What are inhibitors? - CORRECT ANSWERS In plants: ABA (abscisic acid) involved in abscission of leaves,
...
Synthetic: several used as height and stem retardants
What are the methods of application? - CORRECT ANSWERS * spray:
> usually newly formed leaves are targeted
> check for phytotoxicity before applying
> many materials can cause chlorosis, burning,... check label
* Drench:
> may be useful if the material is translocated thorugh the roots; otherwise drenching is not feasible
> more laborious to get uniform dosage
> pay attention to watering prior to drench
Formulation will either be wettable powder or concentrated liquid
> note that carrier can affect plants: residue on leaves, phytotoxicity

foliage plants - height control and greener foliage
azalea - earlier and enhanced flower bud formation
What is Chlormequat chloride? - CORRECT ANSWERS Cycocel, CCC, Citadel; make shorter
applied either as spray or drench - spray may cause chlorosis on leaves, but these are later hidden;
height control; some bud formation
poinsettia, osteospermum, hibiscus - height control
geranium - height control, early flowering (promotes branching)
azalea - earlier flowering
What is Ancymidol? - CORRECT ANSWERS A-Rest, Abide; make shorter
applied either as drench or spray, depending on crop and stage; height control
* Loses activity at low pH
If you drench with it, don't use with pine bark medium (redwood is OK)
Easter lily, Poinsettia - height control (either spray or drench)
bedding plants, foliage plants - height control (spray)
What is Flurprimidol? - CORRECT ANSWERS Topflor; make shorter
* relatively recent introduction in USA

What is protected cultivation and Controlled Environment Agriculture? - CORRECT ANSWERS Protected
cultivation - plants are "protected" from adverse conditions; ideally removal of all such conditions will be
best
Controlled Environment Agriculture (CEA) - complete control over all environmental factors; more than
just "protection" - we seek optimization
- production efficiency
- disease and pest management
- post-harvest treatment
What types of crops are grown in greenhouses? What mediums? - CORRECT ANSWERS Crops:
- Ornamental plants
- flowering plants
- Foods (vegetables, fruit,...)
- Plants grown for essential compounds: herbs, spices, medicinal, etc
Mediums:
- Soilless culture (roots are in substrate, liquid, or air - no field soil)
- In-ground production (in amended field soil)
What are some important issues or considerations when managing a greenhouse? - CORRECT ANSWERS
many technological tools are use, bug you cannot just indiscriminately use all possible tools; you must
understand how the costs return on investment (eg. automation, lamps,...)
- Economics (we grow to fit Marketing and Sales)
