Why do pine trees twist

Choose species that have this tendency. It cannot be certain that an individual young plant will develop pronounced twists.

Some trees have been trained to grow in a twisted manner. Jack Pine Pinus banksiana, U. Department of Agriculture hardiness zones 2 through 6 has crooked branching and trunk growth when grown in open rather than forested situations, giving it somewhat of a bonsai appearance. Scotch pine Pinus sylvestris, USDA hardiness zones 3 through 7 also has an irregular and contorted growth habit. Young trees have an upright pyramidal form, with gnarled growth developing as the tree ages.

Japanese black pine Pinus thunbergii, USDA hardiness zones 5 through 9 exhibits crooked, contorted growth which is enhanced when planted in exposed locations. Picturesque for its thick fissured gray bark, cork oak Quercus suber, USDA hardiness zones 7 through 9 can form a twisted trunk. Skatter and Kucera are convinced that evolution and genetic factors are helping to create the twist.

When radiata pines were grown in New Zealand, they kept their right-handed spiral, even though the trees were in the southern hemisphere. This suggests that the trees have evolved to resist the wind. Skatter is hoping to test his hypothesis by seeing if conifers that grow in areas with different wind patterns have evolved different spiral patterns.

Unfortunately, the local conifers turned out not to have a strong spiral pattern at all, so the matter is still up in the air. Trending Latest Video Free.

Green arrows represent nutrients being distributed through the spiral structure to all aspects of the tree. This work shall be and remain at all times the shared property of Emily Harrington and the Biomimicry 3.

Cellulose fibers in plant stems increase toughness by winding around tubes at an angle. For inexplicable reasons, many trees start growing spirally under strong pressure from wind and snow, as is often encountered in the mountains or in subarctic regions.

Since this spiral growth offers the plant better protection against mechanical destruction, it may well be regarded as a kind of defensive reaction. The shell of a tortoise withstands pressure through interlocking scutes of various shapes consisting of both rigid and flexible layers.

Quills of the North American porcupine penetrate tissue easily due to stress concentration at the barbs that likely stretches or tears tissue fibers locally at the interface of the quill.

The teeth of chitons resist cracking because of the highly ordered, submicroscopic architecture that features a partnership between hard mineral crystals and fibers. Branching design lessens chances of trees breaking by structurally reducing wind stress. Buttresses of the red mangrove enable growth in thin soils by efficiently increasing footprint.
