Pecan

The pecan is a very large tree.

It grows in warm lands. It likes moist soil.

The tree grows a thick husk. This husk starts out green. Then it turns brown. The husk splits into four parts. This lets the seed fall out. The seed is a tasty nut.

You can eat them as a snack. Many people use them in sweet pies. Pecans are a yummy treat!

The pecan is a very large tree. It can grow up to 130 feet tall.

These trees are native to the Southern United States and Mexico. They grow best in hot and humid places. They also need lots of water.

The pecan is not actually a true nut. It is a drupe. A drupe is a fruit with one hard pit inside. This pit is surrounded by a husk.

The husk starts out green. As it grows, it turns brown. Then, the husk splits into four parts. This lets the seed fall out.

People love to eat the seeds. They have a buttery flavor. You can eat them as a snack.

You can also use them in treats. People make pecan pie and praline candy. Some people even use the wood for furniture. They also use the wood to smoke meat. This gives the food a sweet flavor. Many states in the U.S. use the pecan as their state nut.

The pecan tree is a huge and important part of nature. It is a large deciduous tree, which means it loses its leaves each year. These trees can grow to be 130 feet tall. They often have a wide spread of about 60 feet. The trunk can even grow to be 3 feet wide.

Pecans are native to the Mississippi River region. This includes the southern United States and northern Mexico. They grow best in hot and humid summers. These trees also need plenty of water to grow well.

Learning how a pecan grows is very interesting. The fruit is actually a drupe, not a true nut. A drupe is a fruit with a single pit inside. The fruit has a thick outer husk that starts out green. As the fruit matures, the husk turns brown. Then, the husk splits into four sections. This allows the thin-shelled seed to fall out.

This way of spreading seeds happened a long time ago. The tree changed from using wind to using animals to move its seeds.

People have known about pecans for a very long time. Native Americans knew them as a special treat. They may have even helped the trees spread by planting them. Commercial growing in the United States did not start until the 1880s. In 1927, a group called the National Pecan Growers Association made a rule. They decided the official way to say the name is "pea-con."

This helped people agree on how to say the word.

Today, pecans are grown in many different places. The United States produces a huge amount every year. Most of these come from Georgia, New Mexico, and Texas. In 2017, Mexico produced nearly half of the world's pecans. South Africa is also a large producer today.

Many U.S. states love the pecan. Alabama, Arkansas, California, Louisiana, and Texas all call it their state nut. Texas even calls it its state tree.

We use pecans in many tasty ways every day. The seeds have a rich and buttery flavor. You can eat them as a simple snack. People also use them to make pecan pie or praline candy. You might even find them in cookies or ice cream. Some people use the wood to make furniture or floors. The wood can also be used to smoke meat. This gives the food a sweet and nutty taste.

The pecan (Carya illinoinensis) is a large deciduous tree native to the Mississippi River region. This area includes the southern United States and northern Mexico. The pecan is a member of the Juglandaceae family. This family includes more than 60 species of plants. Most of these species live in the Northern Hemisphere of the New World. The pecan is highly valued for its edible seed. This seed is used in many snacks and desserts. It is the state nut of Alabama, Arkansas, California, Louisiana, and Texas. Texas even recognizes the pecan as its state tree.

Understanding how a pecan grows requires looking at its unique structure. While many people call it a nut, it is technically a drupe. A drupe is a fruit that has a single stone or pit surrounded by a husk. The husk is formed from the exocarp tissue of the flower. The part we eat, the seed, develops from the endocarp. The husk is oval or oblong in shape. It starts out green and has a brassy, greenish-gold color. As the fruit matures, the husk turns brown. At this stage, the thick husk splits into four sections. This process releases the thin-shelled seed from the fruit.

The history of the pecan involves deep evolutionary changes. The first fossils of the Juglandaceae family appeared during the Cretaceous period. About 64 million years ago, during the early Paleogene, different subfamilies began to separate. The Engelhardioideae subfamily is generally tropical and evergreen. In contrast, the Juglandioideae subfamily is deciduous and lives in temperate zones. A major step for the pecan was a change in how it spreads seeds. It moved from wind-dispersed fruits to animal dispersion. This change happened as the tree developed a husk. It also involved a change in fatty acids. The ratio of oleic to linoleic acids actually inverted during this transition.

Humans have interacted with pecans for a very long time. Native Americans knew wild pecans as a delicacy. They may have even helped the trees spread by planting them. However, commercial growing in the United States did not begin until the 1880s. There was even a debate about how to say the word "pecan." In 1927, the National Pecan Growers Association set an official rule. They requested that everyone use the pronunciation "pea-con."

Today, pecan production is a massive global industry. In 2014, the United States produced an annual crop of 300,000 metric tons. About 75% of this crop comes from Georgia, New Mexico, and Texas. In 2017, Mexico produced nearly half of the world's total pecans. This volume was similar to the production in the United States. Together, these two countries account for 93% of global production. South Africa has also become a major player. As of 2024, it is the third largest producer and exports mostly to China.

Growing pecans successfully is a complex task for farmers. Pecan trees need long, hot, and humid summers to thrive. They also require large amounts of water. Many orchards use flood irrigation to help the trees grow. Farmers must also manage pollination carefully. Most varieties require two or more different cultivars to pollinate each other. Growers look at the Alternate Bearing Index, or ABI. This index describes how likely a tree is to produce crops every other year. They also group trees by their pollination timing. Some are protandrous, meaning they shed pollen before receiving it. Others are protogynous, meaning they shed pollen after they are receptive.

Maintaining a healthy pecan orchard involves fighting many challenges. Diseases like pecan scab can be very destructive. This is especially true in humid conditions. Farmers often use fungicides to prevent this. Insects also pose a threat to the leaves and stems. Many different types of bugs feed on the trees, including weevils and aphids. Sometimes, the trees suffer from nutrient deficiencies. For example, a lack of nickel can cause a disorder called "mouse-ear." A lack of zinc can cause the leaves to grow in a crowded pattern called rosetting.

Despite these challenges, the rewards of the pecan are great. The seeds are rich in nutrients and flavor. A single serving of 28 grams provides 690 calories. It is a very high source of manganese and thiamine. The seed is also composed of 72% fat and 9% protein. People use pecans in many delicious ways. They are a main ingredient in pecan pie and praline candy. You can also find them in cookies and ice cream. Beyond food, the wood is very useful. It is used to make furniture and flooring. It is also used as fuel to smoke meats, adding a sweet flavor.
