Abstract

In grapes of Cabernet Sauvignon, berry growth, content of anthocyanin and hormonal composition affected by seed number were investigated.
Gibberellin-like substance content showed highest values 45 d after anthesis, while abscisic acid content (on a per-berry basis) had two peaks, the first one just after berry set, the second coinciding with ripening phenomenon.
Seed number was positively correlated with the cöncentrations of gibberellinlike substances and abscisic acid (on a per-berry basis). One-seeded berries, however, had a higher amount of anthocyanin than two or three-seeded ones.

Beziehungen zwischen Anzahl der Samen sowie Gibberellin- und Abscisinsäuregehalt und Reifeverlauf der Traubenbeeren bei Cabernet Sauvignon

Bei den Trauben von Cabernet Sauvignon wurden das Beerenwachstum, der Anthocyangehalt und die Zusammensetzung der Phytohormone in Beziehung zur Anzahl der Samen untersucht.
Die Gibberellinaktivität erreichte 45 d nach der Anthese ihren höchsten Stand, während der Abscisinsäuregehalt (je Beere) zwei Maxima zeigte; das erste trat kurz nach dem Beerenansatz auf, das zweite fiel mit dem Beginn der Beerenreife zusammen. Die Anzahl der Samen war positiv mit der Gibberellinaktivität und der Abscisinsäurekonzentration (je Beere) korreliert. Einsamige Beeren. wiesen jedoch einen höheren Anthocyangehalt als zwei- oder dreisamige Beeren auf.
