The avocado (Persea americana), a tree likely originating from south-central Mexico, is classified as a member of the flowering plant family Lauraceae. The fruit of the plant, also called an avocado (or avocado pear or alligator pear), is botanically a large berry containing a single large seed. Avocados are commercially valuable and are cultivated in tropical and Mediterranean climates throughout the world. They have a green-skinned, fleshy body that may be pear-shaped, egg-shaped, or spherical. Commercially, they ripen after harvesting. Avocado trees are partially self-pollinating, and are often propagated through grafting to maintain predictable fruit quality and quantity. In 2017, Mexico produced 34% of the world supply of avocados. [图片]Persea americana, or the avocado, possibly originated in the Tehuacan Valley in the state of Puebla, Mexico, although fossil evidence suggests similar species were much more widespread millions of years ago. However, there is evidence for three possible separate domestications of the avocado, resulting in the currently recognized Mexican (aoacatl), Guatemalan (quilaoacatl), and West Indian (tlacacolaocatl) landraces. The Mexican and Guatemalan landraces originated in the highlands of those countries, while the West Indian landrace is a lowland variety that ranges from Guatemala, Costa Rica, Colombia, Ecuador to Peru, achieving a wide range through human agency before the arrival of the Europeans.The three separate landraces were most likely to have already intermingled in pre-Columbian America and were described in the Florentine Codex. The earliest residents were living in temporary camps in an ancient wetland eating avocados, chilies, mollusks, sharks, birds, and sea lions. The oldest discovery of an avocado pit comes from Coxcatlan Cave, dating from around 9,000 to 10,000 years ago. Other caves in the Tehuacan Valley from around the same time period also show early evidence for the presence and consumption of avocado. There is evidence for avocado use at Norte Chico civilization sites in Peru by at least 3,200 years ago and at Caballo Muerto in Peru from around 3,800 to 4,500 years ago. The native, undomesticated variety is known as a criollo, and is small, with dark black skin, and contains a large seed. It probably coevolved with extinct megafauna.The avocado tree also has a long history of cultivation in Central and South America, likely beginning as early as 5,000 BC. A water jar shaped like an avocado, dating to AD 900, was discovered in the pre-Incan city of Chan Chan. The earliest known written account of the avocado in Europe is that of Martín Fernández de Enciso (circa 1470–1528) in 1519 in his book, Suma De Geographia Que Trata De Todas Las Partidas Y Provincias Del Mundo. The first detailed account that unequivocally describes the avocado was given by Gonzalo Fernández de Oviedo y Valdés in his work Sumario de la natural historia de las Indias in 1526.The first written record in English of the use of the word 'avocado' was by Hans Sloane, who coined the term, in a 1696 index of Jamaican plants. The plant was introduced to Spain in 1601, Indonesia around 1750, Mauritius in 1780, Brazil in 1809, the United States mainland in 1825, South Africa and Australia in the late 19th century, and Israel in 1908. In the United States, the avocado was introduced to Florida and Hawaii in 1833 and in California in 1856. Before 1915, the avocado was commonly referred to in California as ahuacate and in Florida as alligator pear. In 1915, the California Avocado Association introduced the then-innovative term avocado to refer to the plant. [图片]The word "avocado" comes from the Spanish aguacate, which in turn comes from the Nahuatl word āhuacatl [aːˈwakat͡ɬ], which goes back to the proto-Aztecan *pa:wa which also meant "avocado". Sometimes the Nahuatl word was used with the meaning "testicle", probably because of the likeness between the fruit and the body part. The modern English name comes from an English rendering of the Spanish aguacate as avogato. The earliest known written use in English is attested from 1697 as "avogato pear", a term which was later corrupted as "alligator pear". Because the word avogato sounded like "advocate", several languages reinterpreted it to have that meaning. French uses avocat, which also means lawyer, and "advocate" — forms of the word appear in several Germanic languages, such as the (now obsolete) German Advogato-Birne, the old Danish advokat-pære (today it is called avocado) and the Dutch advocaatpeer. In other Central American and Caribbean Spanish-speaking countries, it is known by the Mexican name, while South American Spanish-speaking countries use a Quechua-derived word, palta. In Portuguese, it is abacate. The fruit is sometimes called an avocado pear or alligator pear (due to its shape and the rough green skin of some cultivars). The Nahuatl āhuacatl can be compounded with other words, as in ahuacamolli, meaning avocado soup or sauce, from which the Spanish word guacamole derives. In the United Kingdom, the term avocado pear is still sometimes misused as applied when avocados first became commonly available in the 1960s. Originating as a diminutive in Australian English, a clipped form, avo, has since become a common colloquialism in South Africa and the United Kingdom.It is known as "butter fruit" in parts of India. *Nutrients and fat composition* A typical serving of avocado (100 g) is moderate to rich in several B vitamins and vitamin K, with good content of vitamin C, vitamin E and potassium (right table, USDA nutrient data). Avocados also contain phytosterols and carotenoids, such as lutein and zeaxanthin. [图片]Avocados have diverse fats. For a typical avocado: -About 75% of an avocado's energy comes from fat, most of which (67% of total fat) is monounsaturated fat as oleic acid. -Other predominant fats include palmitic acid and linoleic acid. -The saturated fat content amounts to 14% of the total fat. -Typical total fat composition is roughly: 1% ω-3, 14% ω-6, 71% ω-9 (65% oleic and 6% palmitoleic), and 14% saturated fat (palmitic acid). Although costly to produce, nutrient-rich avocado oil has diverse uses for salads or cooking and in cosmetics and soap products. Avocados are also a good source of vitamins B, E, and C, copper and fiber; their potassium content is higher than bananas.

Dactylis glomerata, also known as cock's-foot, orchard grass, or cat grass (due to its popularity for use with domestic cats) is a common species of grass in the genus Dactylis. It is a cool-season perennial C3 bunchgrass native throughout most of Europe, temperate Asia, and northern Africa. Cock's-foot grows in dense perennial tussocks to 20–140 cm (8–55 in) tall, with grey-green leaves 20–50 cm (8–20 in) long and up to 1.5 cm (5⁄8 in) broad, and a distinctive tufted triangular flowerhead 10–15 cm (4–6 in) long, which may be either green or red- to purple-tinged (usually green in shade, redder in full sun), turning pale grey-brown at seed maturity. The spikelets are 5–9 mm (0.20–0.35 in) long, typically containing two to five flowers. It has a characteristic flattened stem base which distinguishes it from many other grasses.It flowers from June to September. Cats chew on grass to help get healthy vitamins, minerals, and enzymes, but an indoor cat doesn’t have access to your lawn. Luckily, cat grass is very easy to grow indoors so you can provide your cat the nourishment it needs. Cat grass is usually a mix of wheat, oat, barley, or rye, and can be grown in soil or with a water substrate. Once you have the grass pot set up, your cat can enjoy eating it whenever it wants! [图片]*How to grow 1. Fill a pot with planting soil until it’s 2 inches (5.1 cm) from the rim. Use an organic potting soil, so it’s safe for your cat to dig into. Choose a pot with a wide opening on top so the grass can spread out as it grows. Avoid using any fertilizers in your pot since cat grass grows and dies within a few months. 2. Scatter seeds in the pot and cover them with a thin layer of topsoil. Spread the seeds evenly across the soil until it’s completely covered. It’s okay for the seeds to overlap since the grasses’ root systems don’t take up much room. Once your seeds are in the pot, cover them with about 1⁄4 in (0.64 cm) of soil. Cat grass seed packs can be purchased from your local pet store, garden center or online. You may soak the seeds in a bowl with water one day before you plant them to help speed up germination. The seeds will absorb the water and are more likely to sprout within a few days. 3. Mist the soil until it’s moist. Put water in a spray bottle and gently mist the topsoil. Keep spraying water onto the soil until it feels damp to the touch. Don’t leave any standing water on the surface or else your seeds may not grow.Don’t pour water directly into the pot since it might drown the seeds and prevent growth. 4. Cover the pot for 2-3 days with plastic wrap and keep it in a cool, dark place. Plastic wrap helps maintain a humid environment and encourages your grass to sprout quickly. After you cover the pot, use a toothpick to poke a few holes into the plastic wrap so air can circulate. Store the pot in a cool and dark place, such as a kitchen cabinet or closet. After three days or when you see sprouts, remove the plastic wrap. [图片]5. Move the pot, so it gets natural light and waits ten days for the sprouts to grow. Set the pot in an area of your home that gets direct and indirect sunlight throughout the day, such as a windowsill. After about ten days, the grass will be fully grown and ready for your cat to chew on.
