Toxicity 4. Growing indoors 5. Breeding 6. Cultivation 7. Culinary uses 8. History A. The avocado originated in Mexico. The native uncultivated variety is small, with dark black skin, and contains a large seed. The oldest evidence of avocado use, which dates to around 10 000 BC, was found in a cave in Mexico. The avocado tree also has a long period of cultivation in Central and South America. A water jar shaped like an avocado, dating to AD 900, was discovered in the pre-Incan city of Chan Chan. B. The word avocado comes from the Spanish aguacate. Avocados were known by the Aztecs as the fertility fruit. In some countries of South America, such as Argentina, Bolivia, Chile, Peru, and Uruguay, the avocado is known by its Quechua name palta. The fruit is sometimes called an avocado pear or alligator pear due to its shape and the rough green skin. It is known as Butter Fruit in parts of India. C. The avocado tree does not tolerate freezing temperatures, and can be grown only in subtropical or tropical climates. High winds reduce the humidity, dehydrate the flowers, and affect pollination. When even a mild frost occurs, premature fruit drop may occur. The trees also need well-aerated soils, ideally more than 1 m deep. These soil and climate conditions are available only in a few areas of the world. D. An average avocado tree produces about 500 avocados annually. Commercial orchards produce an average of seven tonnes per hectare each year, with some orchards achieving 20 tonnes per hectare. The avocado is a climacteric fruit, which means it matures on the tree, but ripens off the tree. Avocados used in commerce are picked hard and green and kept in coolers until they reach their final destination. E. Avocados are often grown from pits. This is done by removing the pit from a ripe, unrefrigerated avocado. The pit is placed in a jar or vase with tepid water. In four to six weeks, it should split and out should come roots and a sprout. Once the stem has grown a few inches, it is placed in a pot with soil. It should be watered every few days. Avocados have been known to grow large, so owners must be ready to repot the plant several times. F. The fruit is not sweet, but fatty, and distinctly yet subtly flavoured. It is used in both savoury and sweet dishes, though in many countries not for both. The avocado is very popular in vegetarian cuisine as a substitute for meats because of its high fat content. Generally, avocado is served raw, though some cultivars can be cooked for a short time without becoming bitter. Avocados are also used to make salads. G. Avocado leaves, bark, skin, or pit are documented to be harmful to animals. Cats, dogs, cattle, and horses can be severely harmed or even killed when they consume them. Avocado leaves contain a fatty acid derivative, persin, which in sufficient quantity can cause equine colic and, without veterinary treatment, death. Birds also seem to be particularly sensitive to this compound. Negative effects in humans seem to be primarily in allergic individuals.
