8. Plant Science and its three major areas
Plant Science – the study of structure, functions, growth, and protection of plants.
3 areas of plant science:
Field Crops
Horticultural Crops
Forest Crops

9. Field Crops
Plants grown in large fields used for oil, fiber, grain, and similar products.
They are often grown for their seed, such as corn and wheat.
Agronomy: the specialized area of plant science that deals with field crops.

10. Horticultural Crops
Plants grown for food, comfort, and beauty.
In some cases, horticulture overlaps with field crops.
However, in most cases, horticultural crops are not grown on vast areas of land.

11. Forest crops – production of trees
Forestry includes growing trees and the production of wood, food, and medicinal products.
Some forest crops are grown on tree farms or cultured forests.
Careful thought and planning goes into the production of forest crops on tree farms.

12. Common field crops and their uses
Grain crops
Sugar and oil crops
Fiber crops

13. Grain Crops
Plants grown for their edible seeds, does not include horticultural crops.
Cereal grain is the seed of grass type plants grown for food and animal feed.
Grain and cereal crops include rice, corn, wheat, oats, barley, rye, and sorghum.

14. Sugar and Oil Crops Are produced for two important commodities:
sweeteners
vegetable oil.

15. Sugar Crops – source of sucrose
Sucrose: commonly used as table sugar or as a sweetener in foods and beverages.
It is a carbohydrate that provides energy for the human body.
The major sugar crops are sugar cane and sugar beets.

16. Oil Crops
Plants grown for the vegetable oil contained in their seeds and fruit.
The seeds of about 40 crops are used to make oil.
Soybeans, corn, and cotton are the most common oil crops.
Other oil seeds include sunflowers and peanuts.

17. Fiber Crops
Are grown for the fiber produced in their fruit, leaves, or stems.
Fibers are tiny, threadlike structures used in making cloth and paper.
Crops grown for fiber include cotton and flax

18. Cotton and Flax Cotton is the major crop grown for fiber.
Flax is also grown for fiber.
It is the subject of considerable research because of its potential in making paper.

19. Horticultural crops and their uses
Two major areas of Horticulture:
Ornamental
Food crop production

20. Ornamental Horticulture
Growing and using plants for their beauty.
It includes:
floriculture
landscape horticulture.

21. Floriculture
The production and use of plants for their flowers and foliage.
Roses and chrysanthemums are examples of floriculture crops.

22. Landscape Horticulture
Growing and using plants to make the outdoor environment more appealing.
It includes shrubs, lawns, and flowering plants.
Interiorscaping: using plants indoors to create an attractive environment.
Offices and malls often use plants to increase the appeal of their surroundings.

23. Food crop horticulture
Growing plants for food.
Is divided into two areas:
Olericulture
Pomology

24. Olericulture
The science of producing vegetable crops like tomatoes, peppers, asparagus, and broccoli.
It is carried out on a large scale in warmer areas of the country like South Florida, Texas, and California.
In New Mexico most commercial vegetable production takes in the lower Rio Grande valley in the Las Cruces, Hatch and Deming area.

25. Pomology The science of producing fruits and nuts.
It includes growing, harvesting, and marketing the crop.
Common pomology crops include oranges, lemons, apples, cherries, pecans, and walnuts.

26. Forestry
The art and science of managing forests to yield maximum forest products and services.
It is the managing of forest lands to meet human needs.

27. Forest Products - Crown
The crown of the tree is the upper portion of the tree.
The crown produces such items as fruits and nuts, decorations, and oils.

28. Forest Products - Trunk
The trunk is the main stem of the tree. It is used in producing lumber and other wood products.
The tree’s bark is also used in producing oils, dyes, and drugs.
The bark of the Pacific Yew is used in making the drug taxol, which holds promise in treating cancer.

29. Forest Products – Stumps/Roots
Tree stumps are used in making veneer wood products.
They are also used in producing turpentine, pine oil, and resin.
Tree roots are used in the production of tea, oil, and turpentine.
