Interesting secrets about Christmas trees

Decorating Christmas trees is what families still do on Christmas Eve. However, there are interesting facts that few people know about Christmas trees. Let's try to understand what these interesting facts are.

When the temperature is low, the plant tissue is hard, transparent like glass, the forest is the home of tarantula spiders, the highest tree can reach 130m, can create a separate ecosystem . are characteristics interesting about Christmas tree.

1. The first Christmas tree is actually not a tree. The Germans made this tree from the feathers of dead geese.

2. When the electricity and lights were not invented, people decorated Christmas trees with candles to create a sparkling, warm. Of course this will completely kill the pine tree and then it can only be used as a fence or firewood, cannot be regenerated by replanting for next season.

Pine species can tolerate cold at -196 degrees Celsius.

3. The pine species is cold-tolerant at -196 degrees Celsius. This amazing cold tolerance helps pine trees in the forest of northern Siberia, where winter temperatures drop - 60 degrees Celsius, to survive. Richard Strimbeck, a biologist at the Norwegian University of Science and Technology, thinks that it is possible that cold tolerance comes from making plant tissues into 'glass' form.

In it, the word 'glass' here means transparent solid. However, tissues do not have crystal structures, they are made of sugars, proteins and water molecules, instead of silicon like real glass.

'Once the molecules are in the glassy state, they can't move, meaning they can't react , ' Strimbeck said. Before being frozen, the metabolism of the plant is postponed, allowing the cells to be damaged in extreme cold weather. As winter approaches, the tree also pushes water from the cells to surrounding tissues to help the cell wall not break down.

Christmas trees can become "glass".

4. Christmas tree is the home of tarantula spiders in South Siberia. Tarantula pine and spiders are two things that always appear together like a shadow. In Appalachia's southern mountains between East Tennessee and North Carolina (USA), spruce trees up to 1,645 tall are also home to the world's smallest tarantula - moss microhexura montivaga.

Approximately ¼ cm in length, Microhexura montivag is a highly endangered species and it is difficult to catch them. The whole body is brown, they live very little on the peaks, with small communities. Native fir species (Abies fraseri) and red spruce (Picea rubens) keep rocks and algae below cool, damp, the perfect environment for spiders to live.

5. A sensational news from New York University said, Christmas trees can kill people by "Christmas tree" syndrome. This syndrome causes a range of diseases, including a serious pneumonia. According to the study, a pine has a mold containing germs that can trigger allergic reactions in sensitive people, be wary of it.

6. On average, about 36 million Christmas trees are sold each year and it takes 7 to 10 years for these trees to be regenerated.

7. Each year, a beautiful Christmas tree from Norway will be sent to England as a gift, a thank you. This is considered a symbol of friendship, showing gratitude because he helped Norway during World War II.

8. Naturally grown Christmas tree can create its own ecosystem, providing habitat for wild animals and also significantly contributing to the pollination process in plants. An average Christmas tree contains about 30,000 bugs and insects.

The highest pine forest in the world up to 99.7m, living on soft forest ground in Coos district, Oregon state, USA.

9. Christmas tree can be 130m high. Most pine trees are brought to Christmas decoration only about 10 years old. If there is appropriate time and feeding conditions, pine trees can be as tall as other old trees.

The highest pine forest in the world up to 99.7m, living on soft forest ground in Coos district, Oregon state, USA. Meanwhile, pine trees grown on land near the sea can be as high as 115m. According to the 2004 study, pine can be as high as 130 meters and they cannot be higher due to gravity's influence making it difficult to push water higher.

10. Christmas tree creates its own ecosystem. A Christmas tree with shade by a football field creates a separate ecosystem. 'It's like having another biome on the tree,' said Brian French, a professional climber who studies plants.

Brian French added that for trees higher than 30 meters, the forest floor under the original is wet and porous, while on the tops of trees, the wind blows continuously creating a cool, dry atmosphere. The tree niches, branches are a great hidden place for birds, owls, flying squirrels, mice . At the same time, lichens thrive in perennial plants to provide winter food for squirrels. fly.

Researchers are now worried that climate change may affect native evergreen trees.

11. Pine trees can affect the future climate. Researchers are now worried that climate change may affect native evergreen trees. If winter temperatures are not cold enough, some plants may not receive the necessary message to 'wake up' in the spring.

Temperature also affects plant growth. Cool or warmer temperatures change the physiological development of plants. Extremely high temperatures can be harmful to spruce, fir and their relatives because these plants simply cannot tolerate heat.

12. The use of trees to celebrate in the winter has existed before Jesus was born. Pine trees symbolize proliferation, overcome adversity still sprouting, bouncing.
