Transform pine trees to increase carbon absorption

To maximize the role of plants in carbon sequestration and storage, US researchers have been working hard for more than half a century to improve pine needles.

Finally, they also have significant achievements in improving their ability to absorb carbon dioxide in the air.

Researchers at North Carolina State University have discovered that, between 1968 and 2007, the production of new improved Loblolly pine trees grown in the South East of the United States increased by 17%, but the ability to Its carbon dioxide absorption also increased by 13%.

For the past 40 years, the communication type Loblolly has undergone 3 improvements.

Pine Loblolly is a vigorous, widely distributed tree with a growing period of 25 years. We can easily see it in many parts of the world.

Dr. John S.King of North Carolina State University said they chose Loblolly pine because of its fast growing time, good wood quality, and moreover it is an important tree that constitutes forests, has real value. sacrifice.

Research has shown that, through continuous improvement of many categories, the ability to absorb carbon dioxide and improve the environment of this type of pine also increased markedly.

The forests in the South of the United States currently grow about 1 million pine trees each year, accounting for about 15% of the trees grown here.

Researchers say the study using a method to improve the genetic characteristics of plants to enhance carbon sequestration and sequestration is the first step in the plan to deploy carbon storage on the surface. Large area.

This research result was published in Forest Science magazine published this month.
