Function 1. The ripening season of peaches is in summer, and the fluff on the surface of peaches can block the sun and prevent peaches from getting sunburned.
There is more rain in summer. If too much rain stays on the surface of the peach, the peach will rot and the fluff can separate the rain from the peel. This is why when washing peaches, one of the signs of whether the peaches are clean or not is whether there are peach hairs. Peaches with peach hair indicate that they have not been cleaned.
3. On the whole, sun exposure and rain attack make fruits easy to crack. For example, grapes, pomelos and watermelons without fluff are easy to crack, and the fruit cracking parts are generally located in the upper and tip parts. You can search for pictures of "cracked fruit" on the Internet. In order to reduce fruit cracking, these fruits will grow some characteristics of their own. For example, the grape skin has a layer of reticular fibers, which is to increase the tension of the skin and reduce fruit cracking. Watermelon grapefruit and other skins are thicker, which is also to reduce fruit cracking.
This layer of fluff can also prevent some insects from crawling and invading. Compared with the legs of insects, the toughness of these hairs is a big obstacle. Take spiders for example. When a spider crawls on a fluffy peach, its crawling speed drops obviously and it will trip over the fluffy peach. Just like people would rather walk on flat ground than walk among reeds. Pests can only invade peaches from places without fluff.
Nectarine is a variety of nectarine. Nectarine has no hair, so it can only rely on long waxy peel to prevent rain and insects, so as to make up for its weakness of no fluff.
6. Nectarine tastes hard and sour. Peaches are fluffy and taste good, but if they are not washed, they are easily allergic.
Now forestry science and technology are gradually developing, and peaches with good taste are crossed with nectarines, which are big, red, sweet and hard ... to grow high-quality peaches with smooth surface, beautiful appearance, sufficient moisture, sweet and delicious.
