Conteúdo: | A constant low auxin leveI was observed in a normally setting trimmed cluster of the <tetraploid grape 'Kyoho' (Vi tis vinifera L. x Vitis labrusca L.). The basipetal auxin transport in the trirnmed cluster was always 2-3 times higher than the acropetal transport during the flowering-period. In a non-treated cluster, showing a tendency towards excessive berry abscission, the auxin leveI in the apicaI parts of the cluster fluctuated within the range of 2()-7 Otimes that of the auxin content at full bloom. The ratio of basipetaI to acropetaI auxin transport was nearly unity or less than unity. The results support the hypothesis of apicaI dominance and auxin gradient in the formation of an abscission zone.
