Leaves of trees in summer and autumn

No matter how good the summer, but it is time, when the surrounding greenery becomes scarlet, and nature slowly, beautifully and majestically prepares for a winter rest. From early spring to this time, we observe how the green leaves of trees appear and form from the buds, which, in each period of their development, have a slightly different shade.

What is the reason for this difference in tones, and where does the green color fall in the autumn season?

In the summer, trees grow, increase their root system, expand the crown. They have new branches, and in order to have enough vitality, they have leaves - powerful optical plants or even factories, which are aimed at receiving and preserving, and then transferring the entire plant to light energy. The leaves of the trees have many other important functions, one of them - breathing, and the other - nutrition.

As a result of the unification of these functions, continuous biochemical processes take place here, a sunlight battery - chlorophyll, a collector of hydrocarbon, carbon dioxide and a producer of free oxygen - xanthophylls, a lot of carotene, a vitamin having an orange tinge, and a lot of different vitamins, including very Red anthocyanins. It is the presence of such a rich composition, in fact, a natural pharmacy, is valued by folk healers who use tree leaves to treat diseases in humans.

However, chlorophyll prevails in early summer, so much that the presence of other coloring elements with the naked eye is almost not noticeable. The word "almost" means that each of us sees that a different leaf of the tree has different shades. The shade is the visible part of the spectrum formed by other elements that change the emerald color characteristic of pure chlorophyll in that which is inherent in the species of the plant.

Young greens contain less tannins and other coloring vitamins, so it is more tender and bright. Over time, a lot of substances are produced and accumulated in the leaf, including metals and microelements. They also change the shade, making the greens more complete, saturated and with specific, inherent in this species, distinctive features.

Closer to autumn, the sun begins to decrease its activity. It sends to the earth with each passing day less and less energy. Naturally, for its reception and processing, the leaves of trees no longer need such an excessive amount of chlorophyll, so its content begins to decline, and the production of other vitamins and trace elements that feed the plant continues. Therefore, the appearance of the first yellowish, reddish harbingers of autumn does not mean the withering away of the foliage, but serves only as a transition to a new functional state.

In the last warm days of the year, all nature is decorated with very bright and incredibly beautiful leaves of trees, the photos show well its magnificent crimson, which indicates the preparation for a long winter rest. To any person, any state of the surrounding plant world is favorable. We tend to love and enjoy all the manifestations of his beauty.
