Transcript of Apples ( Malus domestica )
APPLES(MALUS DOMESTICA)
By Monica Sweeney
ORIGINS AND HISTORY Highly debated Originated in Asia
SE Asia Caucasus Kazakhstan Georgia
Neolithic (9500-4500 BCE) 6500 BCE: Anatolia (Turkey) 1300 BCE: Egypt 700 BCE: Greece 44 BCE: England and France Followed Christianity throughout Europe Brought to North America and Australia by colonizers Spread across North American continent by settlers
SOCIOCULTURAL LINKS Found in some of the oldest writings Myths and folklore
Greek legends Biblical stories Medieval Germany folklore
Customs Symbols Sayings Games Company trademarks
DEMOGRAPHIC VARIANCES The “American fruit” – Ralph Waldo Emerson
Popular and widespread Moderately priced
Mostly grown in more industrialized countries Historically
Were rare and expensive in ancient Greece 1600s: Grow by kings and the wealthy and
powerful
COLONIAL AMERICA Apples important part of colonial life
Grown in almost any climate Spread across continent Provided: wood, apple vinegar, food for winter, and
CIDER Cider
Safer than water Exempt from the Prohibition at first
Sign of settlement Ohio land grants: plant 50 apple or pear trees Kept settlers there
Sweet apples were a treat Johnny Appleseed
THE GLOBAL ECONOMY 2nd most popular fruit One of most widely grown Global production
Grown in about 90 countries (2004) 13 million acres (2004) Over 140 billion lbs/yr (2005) Apple exports: 8.5 million apples (2007)
US production Grown in over 35 states Almost 400 thousand acres (2004) 10.1 billion lbs/yr (2004) Apple industry worth: $176 billion (2004)
CLONING Heterozygous: high variability No seed will grow up to be like parent tree Allows for diversity and survival in diverse
environments
Causes problems for human cultivators Grafting High susceptibility to pests and
disease
PESTICIDE USE Need more pesticides than any other food
crop 100s of insects feed on them Numerous diseases Excessive pesticide use due to poor risk
assessment Severe consequences
Pest resistance Killing of natural predators Decrease in biodiversity Ingested by humans
GENETIC MODIFICATION Allows apples to:
Grow in harsher climates Be pest, disease, or herbicide resistant Produce more fruit
Hybridization Negative effects
Patent protection Harm or kill non-target species Unknown effects on human consumers Scare away consumers
LAND USE AND ENVIRONMENTAL EFFECTS Initial land clearing
Habitat loss Decreased
biodiversity Exotic species
Pesticides and fertilizers Effect ecosystem Farm workers Get into soil and
groundwater
THE APPLE INDUSTRY 1900s: Marketing as wholesome, healthy food
Research into apple’s health benefits Growing only a few varieties
Turn of the century: 1000s of varieties sold 1976: 13 varieties, 90% of market
Refrigeration National market possible
Corporations Control through patents
Apple market 55-60% Fresh apples 12-15% Canned 2-3% Dried 2-3% Frozen 20-25% Juice, cider, applesauce, vinegar, etc.
ALTERNATIVE STRATEGIES Organic, local, sustainable apples possible! Hurtles:
Susceptibility to pests and disease Natural pesticides Natural predators Diversity GM apples
Use of fertilizers Nitrogen fixing cover crops
Storage and preservation Paraffin wax coating Controlled Atmosphere (CA) Storage
