Poplar Tree

The Poplar Tree was already there at the beginning of the summer. Without the stand of trees for cover, the temperate rain had already softened the ground to mud. Bertiana was there, too, in her leather corset with her hair held back in an intricate braid that flowed down her back.

Poplars are rapid-growing but relatively short-lived trees. They are widely distributed throughout the northern temperate regions, ranging from North America through Eurasia and northern Africa. The leaves are alternate and oval or heart-shaped in outline, with finely to coarsely toothed margins (leaf edges). The leaves characteristically tremble in the breeze, because of their flat petioles (leaf stalks). In North America, aspens usually have nonsticky buds and smooth gray-to-green bark, whereas cottonwoods and balsam poplars have sticky buds and bark that is darker and deeply furrowed. Poplars are dioecious plants, meaning the male and female flowers grow on separate trees. The flowers bloom in drooping catkins (pendulous unisexual flower clusters) before the leaves emerge, to facilitate wind pollination. The fruits are small thick-walled capsules that contain many minute seeds clothed in cottony tufts of silky hairs. The seeds are often released in great quantities, and the fluffy seed hairs assist in wind dispersal. (Source: www.britannica.com)

…large end, great stands of poplar trees entirely connected by common roots are really a single organism. A variety of influences place an upper limit to the size of organisms. One is the strength of biological materials. Sequoia redwood trees, some of which exceed 90 metres (300 feet), are apparently.

The common European aspen (P. tremula) and the American quaking, or trembling, aspen (P. tremuloides) are similar trees and reach a height of about 27 metres (90 feet). Quaking aspen is distinguished by its leaves, which have more-pointed tips, and spreads by rhizomes (underground stems). Clonal colonies of quaking aspen can grow quite large, and the most massive clonal organism on Earth is believed to be a forest of genetically identical trees, known as Pando, in Utah. The American big-tooth aspen (P. grandidentata) grows up to 18 metres (59 feet) and has larger, somewhat rounded, coarse-toothed leaves.

Poplar Farming

Poplar is deciduous tree and belongs to family of Salicaceae. These are fastest growing tree under ideal climatic conditions. Poplars wood and bark are used for making plywood, boards, matchsticks, also for making sports good and pencil. In India, plant can grow upto height of 85 feet or above with in life span of 5 to 7 years. Major poplar producing states in India are Haryana, Punjab, Uttarakhand, Uttar Pradesh, Himachal Pradesh, Jammu & Kashmir, Arunachal Pradesh and West Bengal.

The bark on young trees is smooth, white to greenish or dark grey, and often has conspicuous lenticels; on old trees, it remains smooth in some species, but becomes rough and deeply fissured in others. The shoots are stout, with (unlike in the related willows) the terminal bud present. The leaves are spirally arranged, and vary in shape from triangular to circular or (rarely) lobed, and with a long petiole; in species in the sections Populus and Aigeiros, the petioles are laterally flattened, so that breezes easily cause the leaves to wobble back and forth, giving the whole tree a "twinkling" appearance in a breeze. Leaf size is very variable even on a single tree, typically with small leaves on side shoots, and very large leaves on strong-growing lead shoots. The leaves often turn bright gold to yellow before they fall during autumn.
