Term for the side of the Blattachseln the secondary shoots of the main shoots vine, Synonyms are Aberzahn, Dolder, Drohler, Boar Tooth, Grandson, Geize, Irxe, Kindlein, Ohrlaub and Uchse. In part, this is how the grapes growing on stingy shoots are called. The miser instincts form from the summer bud eye one Triebes, The winter bud next to it then grows into the new summer shoot next spring. Especially with early ones tops of the main shoot, the summer bud can grow into a considerable side shoot, which can even bloom and fruit in the lower part. Most of the time, however, the stinginess remains small or does not sprout at all. Then his bud dies in the following winter due to insufficient wood maturity. Each type of grape tends to be more or less vigorous. By a strong document growth is encouraged.
For varieties with less apical dominance and a strong tendency towards the formation of stinging shoots, these side branches branch out from the leaf axils of the main shoot, which grows in length, early in summer. Such avarice drives then also carry notes from which small grapes develop. However, these mature due to the later ones blossom not enough anymore, are still green and acidic at the time of harvest and must therefore be removed. Old names for the miser grapes are Dolder, Drohler or Härlinge, It used to be used to make a simple, acidic wine, in Austria it was called "Irxenwein". In the past, stinging shoots were basically broken out (flowering) before flowering, but today they are partly left on the stick. Your leaves can be used as a valuable additional assimilation surface in the photosynthesis serve.
Give growing shoot tips auxins (Plant hormones), which suppress the budding of the stinging buds in the subsequent shoot sections. With increasing distance to the tip of the shoot, the effect of the hormone loses, so that in the lower area, stunt shoots can grow out. When the top of the main shoot is peaked, the apical dominance of the long shoot is eliminated, so that stinging shoots can form everywhere. Sometimes, however, only the top stinging bud sprouts out from under the capped tip. The growing Geiztrieb then takes over the apical dominance and continues the length growth of the main shoot alternatively, with a slight curvature at the lateral shoot base and somewhat thinner internodes.
Even in the event of an early failure of the main shoot, stingy buds can develop into fully functional long shoots, which, however, are characterized by late flowering and a reduced growth of the stem. The secondary shoots growing from the lower trunk area are called water shoots designated. However, these do not arise from the axillary buds, as is the case with the miser, but from adventitious, For this reason, water shots and poultry shoots are fundamentally to be regarded as different (although they are often incorrectly referred to as identical in many sources).
