Leaves are the power plants of green plants and next to the roots of the main nutritional organs. At the Rebstock they form like that eyes (Summer and winter eyes), tendrils and inflorescences (Gescheine or later grapes) as lateral outgrowth at the Nodien (Knot) young growing shoots, While the shoot tip grows in length, new leaves branch off constantly, which develop according to a species- and variety-specific blueprint. With the help of leaf pigments like chlorophylls. carotenoids and flavonoids the light energy of the sun is absorbed by the leaves and during the photosynthesis under the use of carbon dioxide and water in high-energy glucose (Glucose) and oxygen transformed. The necessary carbon dioxide is released from the air through the stomata (Stomata) mostly taken on the undersides of leaves. Through these small stomata escapes the daytime produced oxygen to the outside.

Due to the water vapor saturation deficit of the air, each plant cell constantly loses water, which evaporates outwards into the air. This complex process is called evapotranspiration designated. The constant loss is compensated by the subsequent supply of...
