Designation for the type of formation of the annual shoots, Depending on the length of the shoots or when pruning leave on it eyes (Buds) there are different names. A very short shoot is called cones (1 to 3 eyes), a medium-length shoot called Strecker (4 to 7 eyes) and a very long shoot is called tail (8 to 15 eyes). The new, fruit-bearing shoots (summer shoots) develop out of the eyes.
However, there is no uniform standardization in this regard, the number of eyes is often slightly different locally. The term bow is used for both the Strecker and the rod. And Strecker is a name for the medium-length shoot and also for the shape of the flat bow. The left shoots are formed and with the Wire frame support fixed (bending). The individual forms are typical of different educational systems. Today, mostly the flat or half bow is used.
Flat arch (Strecker) : The shoot is placed on the wire or wound around it. With the double flat bow (double stretchers, two-stretchers) one drive is led to the right and left
Half arch : The shoot is formed semicircular over two 15 to 20 cm distant bending wires and fixed to the lower wire. Depending on the vigor, there are one or two semi-arches or a double arch.
Pendulum arch : Is a half arch with very wide bending wire distances of over 30 cm. The sloping arch part is bent down mostly perpendicular, which is like a pendulum. In certain forms of education and the long shoot is left hanging freely. As the drive load increases, the entire arc "sways" downwards.
Full arch (round arch) : The form comes in a Stocker education as in the Mosel pile education for use. A long shoot (also Bügling) is strongly bent and the end attached to the stick. In two shoots, this results in a heart shape (therefore heartcut). A mixed form with half and full sheets is or was used to be one of the many variants of the former, especially in the former Eastern Bloc countries high culture,
