Abstract

The first rapid growth phase of grape berry (stage I) was associatecl with high levels of auxin-like substances ancl low levels of growth inhibitory substances. In the lag phase (stage II) of berry clevelopment high levels of growth inhibitors and low levels of growth promotors were observed. The berry growth in the post-lag phase (st;:ige III) was generally associated with higher levels of gibberellin-like substances.

Die hormonale Steuerung der Phase des verlangsamten Beerenwachstums bei samenhaltigen und samenlosen Reben (Vitis vinifera L.)

In der ersten Phase des raschen Beerenwachstums (I) lagen hohe Konzentrationen auxinartiger Substanzen und niedrige Konzentrationen wachstumshemmender Substanzen vor. Während der anschließenden Phase des verlangsamten Beerenwachstums (II) wurden hohe Konzentrationen von Wachstumshemmern und niedrige Konzentrationen von wachstumsfördernden Substanzen festgestellt. Das erneut beschleunigte Beerenwachstum in der darauf folgenden Phase (III) war im allgemeinen mit erhöhten Konzentrationen gibberellinartiger Substanzen verbunden.
