Why do some trees grow well in cold weather?

Scientists at the University of New South Wales (UNSW) have identified the root system and physiology of a common, winter-adapted plant called a magical sapling.

The sapling is known to be the main food source for some of the world’s most endangered northern and southern white-tailed deer.

The research is published in the journal Plant Ecology.

The magic sapling’s root system is composed of the thorns of a large-march, white-toothed plant called the eastern cottonwoods.

When the thorned stems are pulled away, the leaves turn into a seed pod, with the seedling itself forming the base of the tree.

A typical magical sapler’s leaves are about 2 centimetres wide and 3 centimetrees long.

Researchers found that when the thorn stem is pulled away from the seed, the seeds and the root systems of the magical saplings are separated.

Scientists say the seeds form the core of the plant and the tree is able to survive the coldest months of the year because the seed is able of surviving long distances without rotting or collapsing.

The magic tree’s roots are protected by thick bark that helps them withstand the cold and wind.

“The seeds are actually very robust, so they can withstand the extremes of the climate, even in extreme cases of drought,” Dr Helen Smith, a plant pathologist at UNSW’s Faculty of Agriculture and Natural Resources, said.

Smith said the researchers also noticed that the magical tree’s root systems were adapted to the cold.

It’s a great example of how we’re using the root to protect a plant, rather than just trying to destroy it, Smith said.

“This is a good example of what’s going on with the plant.

They’ve got a good root system.

They have a nice structure.

It’s actually adapted to this very extreme environment.”

Dr Smith said the magical santalum plant is a member of a group of plant species called the winter- adapted tree family.

Winter-adaptive trees are plants that are not only cold-adapting, but are also able to withstand the winter.

Many of the winter adapted trees have thick, bark-like structures called tassels.

They can survive winter temperatures as low as -20 degrees Celsius (-4 degrees Fahrenheit), while other winter-sensitive trees are not able to thrive in these conditions.

There is no known way to stop or reverse this adaptation, Smith noted.

This study is a first step in identifying the root mechanism of magic saplings, and how this might help the forest ecosystem.
