Objective: 3.03 10% C2 Discuss floriculture and landscape plants.

A. Scientific Classification of Plants

1. Taxonomy is the science of classifying and identifying organisms such as plants.

2. Scientific names are necessary because the same common name is used for different plants in different areas of the world.

3. Latin is the language used for scientific classification.

4. Carlos Linnaeus, a Swedish botanist, developed the binomial system of naming plants using two Latin words to indicate the genus and the species.

5. In the scientific name, the first word is the genus (first letter is capitalized) and the second word is the species. If there are additional words after the species, they indicate the variety or cultivar (variety var. or cultivated variety or cv).

a. Plants in the same genus have similar characteristics. b. Plants in the same species (sp.) consistently produce plants of the same types.

6. The broadest category of scientific classification is the Kingdom-either plant or animal.

7. The broadcast category of the plant kingdom is Division or Phylum.

8. The four most important divisions of the plant kingdom are:a. Thallophytes: algae, fungi, and lichens.b. Bryophytes: true mosses and liverworts.c. Pteriophytes: ferns, horsetails, and club mosses.d. Spermatophytes: seed-bearing or flowering plants.

9. The two subdivisions of Spermatophytes a. Gymnosperms are seeds are not in an ovary (cone). b. Angiosperms are seeds enclosed in an ovary (flowering plants).



ESSENTIAL STANDARD: 4.00 10% C3 Examine factors relating to plant growth and development.

Objective: 4.01 5% C2 Explain the growth process of plants.

A. Photosynthesis

1. The food manufacturing process in green plant that combine carbon dioxide and water in the presence of light to make sugar and oxygen.

2. Formula: 6 CO2 + 6 H2O → C6H12O6+ 6 O2

Carbon dioxide + Water + Light energy → Glucose + Oxygen

3. The main product of photosynthesis is sugar.4. The by-product of photosynthesis is oxygen.

F. Reproduction

1. The plant process that increases plant numbers usually from seeds.2. The two main methods of reproduction are sexual and asexual.

G. Osmosis

1. The process by which minerals enter the plant through cell walls.2. The process by which water enters the plant through cell walls.

H. Light

1. Photoperiodism is the response of plants to different amounts of light regarding their flowering and reproduction cycles.a. Short day plants require long nights to flower. Examples are poinsettia and azalea.b. Long day plants require short nights to flower. Examples are African violets and

spinach.2. Phototropism is the tendency for plants to grow toward a light source.

I. Moisture

1. 90% of plant tissue is made of mostly water.2. Water carries nutrients throughout the plant.

J. Stages of plant growth

1. Juvenile is when plants first start to grow from a seed.2. Vegetative is the second stage of growth that begins after the plant begins

photosynthesis and actively grows leaves, stems, and roots prior to flowering3. Reproductive is when plants produce flowers, seeds and fruit.4. Dormant is when plants rest or grows very little.

K. Hardiness Zones1. Plants are categorized by zones based on the average minimum temperature.2. North Carolina is zones 6-8.3. Charlotte is zone 7.



ESSENTIAL STANDARD: 4.00 10% C3 Examine factors relating to plant growth and development.

Objective: 4.02 5% C3 Use sexual and asexual methods of propagation.

B. Asexual Propagation

1. Starting plant by means other than seed.2. Cuttings

a. Stem1) Start with sterile flats, soil, and tools.2) Must include a node. A node is a point along a plant stem where leaves

or other stems are attached. 3) Internode is the area between two nodes.4) Cutting is taking a 4-6 inch piece of the plant and forcing roots to grow.5) Using hormones help speed up rooting.6) Dipping the cutting in fungicides help prevent rotting.7) Herbaceous plants are soft-tissue plants.8) Woody plants are plants that produce woody tissue.9) Rooting media should be about four inches deep.10) Examples of plants that can be started by cuttings.

a) Herbaceous cuttings – geranium, impatiens, begonia, and coleus.b) Woody cuttings – holly, abelia, and rosemary.

b. Leaf

a) African violet and philodendronb) snake plant and jade plant.

c. Root1) Should be spaced three inches apart in rooting area.2) A sand, vermiculite or perlite mixture is a good medium for root cuttings.3) Examples of plants that can be started by root cuttings: hosta and daylily.

d. The best time of day to take a stem, leaf or root cutting is early morning because plants have more moisture.


3. Layeringa. Air layering

1) Making an incision at the node of a branch. 2) Dust with rooting hormone, place sphagnum moss in plastic and wrap

around the incision forcing roots to grow on the stem of the plant.3) Once roots form, remove below the new roots for a new plant.4) Examples of plants to air layer: Decora rubber plant and weeping fig.

b. Trench layering – new plants form at each along the stem while still attached to the plant.

1) Is cutting a trench and laying a branch in the trench. 2) Types of trench layering are simple, tip and serpentine.3) Examples of plants for trench layering: grapes and clematis.

6. Graftinga. Is joining separate plant parts together so that they form a union and grow

together to make one plant.b. Tools needed are a knife, tape, and wax. c. Plants must be related to each other and normally in the same genus or family.d. Scion is the piece of plant at the top of graft.e. Rootstock is the piece of the plant at the root or bottom of graft.f. Examples of plants that can be grafted: Maples and fruit trees, sweetgum

(fruitless sweetgum), and pecan.

7. Budding a. Is a form of grafting when a bud is used instead of a scion. b. Methods of budding:

1) Patch budding. 2) T-budding. 3) Chip budding.

c. Successful budding requires that the scion (top) material have fully-formed, mature, dormant buds and that the rootstock be in a condition of active growth such that the "bark is slipping". This means that the vascular cambium is actively growing, and the bark can be peeled easily from the stock piece with little damage.

d. An example of plant used would be rose.


8. Tissue Culture (or micropropagation)a. A sterile environment is necessary for micropropagation (biotechnology) b. It is a good way to get the most plants in a short period of time.c. It will give you a plant identical to the parent plant.d. An example would be impatiens and many flower and vegetable plants.

9. Additional Plant Propagation Vocabularya. Corm is an enlarged, bulb-like, fleshy structure found at the base of a stem.

Usually flattened and round. Examples: gladiolus and crocus.b. Rhizome is a creeping underground stem, usually horizontal, that produces roots

and leaves at the nodes. Examples: cannas and bearded Iris.c. Stolon is a creeping above ground stem that grows horizontally and produces

roots and shoots at the nodes. Example: strawberry.d. Tuber is a swollen, modified stem that grows underground. Example: potato. e. Sucker is a shoot or stem that originates from the roots.

10. Advantages of asexual reproduction as a propagation method

ESSENTIAL STANDARD: 5.00 10% C2 Explain the properties of soils.

Objective: 5.02 5% C2Discuss the soil profile and soil sampling for surface and subsurface layers.

A. Soil Profile

1. Soil layers are called horizons. All soil profiles do not have the same number or level of horizons. For example, a sandy soil may not have an “O” horizon if it has been under cultivation. Other soils may have an horizon missing due to erosion. Most typical soils in North Carolina will have a minimum of the A, B and C or R horizons.

2. O Horizon – Rich soil found where a plant cover has been in place for an extended timea. Is rich in organic matter. b. O Horizon is rich in organic matter in various stages of decomposition and is dark

in color. c. It is the most fertile layer in the soil profile.

3. A Horizon a. Is the topsoil and most fertile in the absence of an O horizon. b. A Horizon, lies just below O Horizon, is home to earthworms and soil organisms. c. It is brown in color due to the organic matter in the soil.

4. B Horizona. Is the subsoil. b. B Horizon is a clayey soil that has a high mineral content. c. B Horizon is usually brown or reddish due to the large amount of clay.

5. C Horizon a. Is parent material. b. C Horizon consists mainly of clumps of un-weathered rocks.

6. R Horizon a. Is bed rock. b. R Horizon cannot be dug by hand and very few roots can penetrate the bedrock.

B. Soil Structure -

1. Soil structure is how the soil particles fit together2. Sandy soils typically have a loose soil structure.3. Silty soils have a granular soil structure.4. Clayey soils have a blocky or platy structure.5. Granular soil structure is the best. Plants have good root development. Water

movement is at an appropriate rate – doesn’t stay to wet or too dry.


C. Soil Texture1. Sand has the largest particles. Sandy soils have low moisture and nutrient holding

capacity. 2. Silt has medium sized particles. Silt has a good moisture and nutrient holding capacity.3. Clay has the smallest sized particles. Clayey soils have high water and nutrient holding

capacity.4. Loam has almost equal parts of sand, silt and clay. This is the ideal texture for most non

container outside plants.

D. Soil pH

1. Soil pH is a measure of the acidity or alkalinity of soils.2. Soil pH ranges from 0-14. 0-6.9 (low pH) is considered an acid soil, 7 indicates a neutral

soil and 8-14 (high pH) is considered an alkaline soil.3. Lime will raise the pH value in soils (make the soil less acidic).4. Calcium or sulfur will lower the pH value in soils (make the soil more acidic).5. The ideal pH value for vegetable garden soils are 5.5 to 7.0.

E. Physical Properties of Soils

1. Permeability is the rate at which water moves through the soil.2. Water holding capacity is the ability of a soil to hold water for plant use.3. Porosity is the amount of air space between soil particles.4. 50% of soil should be pore space which includes 25% water space and 25% air space.5. 50% of soil should be soil particles which include 45% mineral matter and 5% organic

matter.

F. Soil Sampling1. Soil sampling and testing is essential for an accurate fertilizer recommendation for

growing plants.2. Soil sampling procedures.

a. Create a visual grid of the area to be planted. For gardens and landscapes, take 5-10 subsamples from the site to be evaluated. Sample before the growing season.

b. Use a stainless steel soil-sampling probe.c. Take the surface sample to tillage depth or about 3-4 inches for lawns and 6-8

inches for crops.d. Mix the soil samples together.e. Remove any grass, rocks or other material besides soil.f. Avoid unusual spots in the lawn or field. Those areas need to be sent in a

separate box.g. Place soil samples in a box, which you can obtain from the County Extension

Office along with Soil Sample Information sheet, send the box and information to Agronomic Division Soil Test Lab in Raleigh for a free soil test.

ESSENTIAL STANDARD: 6.00 10% C2 Explain the role of nutrients and fertilizers.

Objective: 6.02 5% C2 Discuss the advantages and disadvantages of various fertilizers.

A. Complete and Incomplete fertilizers

1. A fertilizer analysis label will indicate the amount of nitrogen (N), phosphorus (P) and potassium (K) contained in a fertilizer as a percentage by weight for each element. For example, 10-20-10 will have 10% Nitrogen, 20% phosphorus, and 10% potassium.

2. Complete fertilizers have all three primary elements. N, P, K (10-10-10, 20-5-20).

a. An advantage is the plants receive all essential elements.b. A disadvantage is some plants may not need all essential elements.

3. Incomplete fertilizers do not have all three primary elements. (20-0-0, 0-20-0).

a. An advantage is plants need a selective element.b. A disadvantage is plants may need more elements.

B. Organic or inorganic fertilizers

1. Organic fertilizers are by products of plant or animal matter and contain carbon compounds such as urea, sludge and animal tankage.

a. Advantages1) The fertilizer is released slowly reducing the risk of over fertilizing.2) It is not easily leached from the soil.3) It improves the water holding capacity of the soil.4) Improves the physical condition of the soil.5) Adds organic components to the growing media.

b. Disadvantages 1) It has a smell and is heavy.2) It is expensive.3) Some are not sterile.4) It has low nutrient content.


2. Inorganic fertilizers come from sources other than animals or plants.a. Advantages

1) It contains the three essential nutrients (N, P, and K) in desired amounts.2) The fast release capability makes it readily available for plants.3) It is easy to get as most commercial fertilizers are in an inorganic form.

b. Disadvantages 1) It contains no organic matter.2) It can cause a chemical build up in soil.3) It leaches out in heavy rain or through irrigation.4) It has a high acid concentration which leads to high soil acidity.

C. Soluble and insoluble fertilizers1. Soluble fertilizers

a. Soluble fertilizers dissolve in water and are applied as a liquid solution.b. Water soluble fertilizer applied through irrigation systems.

2. Insoluble fertilizersa. Insoluble fertilizers include granular and slow release fertilizers.b. Granular fertilizers are relatively inexpensive and easy to find.c. Slow release fertilizers are more expensive than granular because they are

coated.d. Slow release fertilizers give a more uniform release of nutrients over a period of

time.

D. Methods of applying fertilizers1. Banding or starter application is placing a band of fertilizer about two inches to the sides

and about two inches below the seed depth. The band method is close enough to efficiently supply the young plants with nutrients, but not too close to damage developing roots.

2. Side-dressing refers to the spreading of fertilizer in between the rows and around the plants after seedling emerge from the soil.

3. Topdressing is mixing the fertilizer uniformly into the top one to two inches of growing media around the plant.

4. Perforating is placing the fertilizer in twelve- eighteen inch holes drilled eighteen to twenty four inches around the drip line of trees. Be sure to cover the holes after fertilizer is applied.

5. Broadcasting is spreading fertilizer to cover the entire production area.6. Fertigation is incorporating water soluble fertilizer into the irrigation system of a

greenhouse or on nursery crops. Concentrated solutions usually pass through an inexpensive proportioner (Hozon) or a more accurate injector (Smith injector) to dilute the correct ratio.

7. Foliar spray is spraying nutrients in a solution directly on plant leaves. It is used to correct nutrient deficiencies, but the fertilizer concentration should not be too high or leaf burn will occur.

1) Chewing insects chew or grind food.2) Chewing insects include beetles, cutworms, caterpillars and

grasshoppers.3) Damage by chewing insects includes tearing, chewing or grinding all

parts of the plant.b. Piercing-sucking

1) Piercing-sucking insects puncture plant and suck sap usually from the underside of the leaves or on the stem.

2) Piercing-sucking insects include aphids, mealy bugs, mites, scale and whiteflies.

3) Damage cause yellow spotted leaves which result in stunted growth.c. Rasping-sucking

1) Rasping-sucking insects rasps or breaks the leaf surface and suck sap.2) An example of a rasping-sucking insect is thrip.3) Damage plant tissue becomes speckled and white

d. Siphoning 1) Siphoning insects dip a coiled tube into a liquid food such as nectar and

draw (or siphon) it in.2) Siphoning insects include butterflies. 3) Siphoning insects do little or no damage to the plant.

ESSENTIAL STANDARD: 9.00 10% C2 Explain Integrated Pest Management and pesticides.

Objective: 9.01 5% C2 Discuss integrated pest management strategies.

A. Integrated Pest Management (IPM)1. IPM is most effective and environmentally friendly method approach to control.2. IPM focuses on pest prevention by identifying, preventing and monitoring pests with the

least amount of danger to the environment by the most economical means.3. According to the EPA, "Integrated Pest Management (IPM) is an effective and

environmentally sensitive approach to pest management that relies on a combination of common-sense practices". (North Carolina Cooperative Extension Service)

4. Chemical pesticides are only one part of the solution so therefore they are used more sparingly and wisely.

A. Steps to integrate IPM

1. Identify the pest.2. Prevention of pests can be controlled by using cultural methods such as crop rotation,

pest resistant varieties and planting pest-free rootstock.3. Monitoring new infestations can be the best controlled by early detection.4. Traps may be used to check pest population.5. Use the less risky pest control first including pheromones that will disrupt pest mating or

mechanical controls including traps.6. If these methods are not effective, additional control methods including target spraying of

a pesticide may be necessary. Broadcast spraying would be used as a last resort.

B. Biological control

1. Lady beetles or lady bugs both adults and larva feed on soft bodied insects (aphids), mites and eggs.

2. Parasitic wasp attack caterpillar, butterfly or moth egg or pupa, beetle egg and other insects in the egg, larva or pupa stage.

3. Praying mantis will eat just about any pest.4. Green lacewing larvae are predators that fee mainly on soft bodied insects, mites, and

eggs.5. Predatory mites will attack spider mites at any stage of development inside a

greenhouse or outside.
