Plant Science and its three major areas
Science – the study of
structure, functions, growth, and
protection of plants.
 3 areas of plant science:
 Plant
 Field
Crops
 Horticultural Crops
 Forest Crops
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.
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.
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.

Common field crops and their uses
 Grain
crops
 Sugar and oil crops
 Fiber crops
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.

Sugar and Oil Crops
 Are
produced for two important
commodities:
 sweeteners
 vegetable
oil.
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.
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.

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
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.

Horticultural crops and their uses
 Two
major areas of Horticulture:
 Ornamental
 Food
crop production
Ornamental Horticulture
 Growing
and using plants for their
beauty.
 It includes:
 floriculture
 landscape
horticulture.
Floriculture
 The
production and use of plants
for their flowers and foliage.
 Roses
and chrysanthemums are
examples of floriculture crops.
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.
Food crop horticulture
 Growing
plants for food.
 Is divided into two areas:
 Olericulture
 Pomology
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.
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.

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.
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.
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.
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.
Review / Summary

plant science?
 What are the uses of common field
crops?
 What are the uses of horticultural
crops?
 What are common products that are
derived from trees?
