Difference between cedar and pine.

Cedar and pine are two trees that belong to the same Pine family. Despite the external similarity, both plants have a number of significant differences.

Definition

Cedar - it is a genus of trees of the Pine family, which consists of only a few species.

Lebanese cedar

Pine is a genus of trees of the Pine family, numbering about 120 species.

Scots pine
Siberian cedar pine

Comparison

Cedars are common within the subtropical climatic zone - the Mediterranean, the mountainous Crimea, the Himalayas. Therefore, there are only a few species of these plants - Lebanese, Himalayan and Atlas cedar.

Pines are common in temperate and subtropical climates in Eurasia and North America. Today there are about 200 species of pine trees on Earth. Pines are evergreens. Depending on living conditions, they look like large trees with a crown of various shapes, and miniature shrubs.

Cedar is a monoecious plant that grows up to 50 meters in height. The tree is evergreen with a characteristic, spreading crown. The needles are arranged spirally, collected in bundles of 30-40 pieces each. A single needle resembles a needle. It can be three-sided or four-sided, painted in a special emerald-steel color.

Pine is a monoecious plant with long or short needles. The bundle contains from two to five long needles, the number of which underlies the taxonomy of pines. In case of damage, rosettes form on the tree, from which short needles grow. The color of the green mass of pine depends on the climate and the quality of the soil, therefore it varies from light silver to intense green.

Cedar cones are located singly, "stick out" like candles, and have a special barrel-shaped shape. Such a cone ripens in the second or third year of its formation. This organ of seed incubation is characterized by the presence of numerous, spirally arranged scales, to which tiny ones are attached - only 15% of the total weight of the cones! - winged seeds. The embryo of the future cedar consists of 8-10 cotyledons. When a seed enters the ground, a sprout of a new cedar is able to grow - "hatch" in just 3 weeks.

Pine cones have a characteristic oblong shape, do not "stick out", but hang sadly from the branches. While the seed is ripening, the scales adhere very tightly, but when ripe they open, "releasing" the seeds. For each scale, there is a pair of winged or wingless seeds. A very small pine bud has 4 to 15 cotyledons. Germination time depends on the species and geographical location of the plant.

Due to the greater distribution and number of species, pine is more intensively used by humans.

Conclusions TheDifference.ru

  1. The number of pine species is ten times greater than the number of cedar species.
  2. The distribution area of ​​pine is much wider than that of cedar.
  3. The morphology and size of the pine is much more varied than that of the cedar.
  4. There are more needles in a cedar bunch than in a pine bunch.
  5. Pine trees are of great economic importance for mankind.
