Abstract

Gibberellin-treated 'Thompson Seedless' grapes were thinned at initiation of berry shatter following bloom or at 1 to 6 weeks thereafter. The results indicate that for maximum increase in berry size, thinning should be done during fruit-set or as soon after as possible.

Der Einfluß des Ausdünnungstermins auf die Beerengröße von geringelten, gibberellinbehandelten „Thompson Seedless"-Trauben

Gibberellin-behandelte „Thompson-Seedless"-Trauben wurden bei Beginn des Durchrieselns oder 1-6 Wo chen danach ausgedünnt. Die Ergebnisse zeigen, daß für einen maximalen Zuwachs der Beerengröße das Ausdünnen während des Fruchtansatzes oder sobald wie möglich danach erfolgen sollte.
