Abstract
In order to arrest vegetative growth of grape shoots, various growth regulating substances were applicated on five grapeVine cultivars: Alphonse Lavallee, Muscat of Hamburg, Cardinal, Perlette, and Queen of the Vineyards. Ethephon at a concentration of 480 ppm efficiently inhibited the terminal growth of the canes and prevented the opening of lateral buds on the shoots for about 8 to 10 weeks. This treatment somewhat enhanced maturation of the current yield. No negative effect on bud differentiation, bud opening and growth in the following season was found. The use of Ethephon was much more effective than the other regulators tested such as Alar, NC 9634, pp 413, and morphactin 7311. Alar caused a shortening of the canes, not effecting the number of nodes. pp 413 had no activity in our system while both the morphactin and NC 9634 did inhibit growth partially. The Ethephon treatment was far more efficient and uniform than repeated manual topping. Regulierung des vegetativen Wachstums von Reben (Vitis vinifera) durch Etephon und andere Hemmstoffe Die hemmende Wirkung verschiedener Wachstumsregulatoren wurde an fünf Rebsorten geprüft: Alphonse Lavallee, Muskat Hamburg, Cardinal, Perlette und Queen of the Vineyards. Etephon hemmte bei einer Konzentration von 480 ppm deutlich das Spitzenwachstum der Triebe und verzögerte den Austrieb der lateralen Knospen um 8 bis 10 Wochen. Diese Behandlung erhöhte den Reifegrad der Traubenernte. Ein negativer Einfluß auf Knospendifferenzierung, Knospenaustrieb und Wachstum in der folgenden Wachstumsperiode wurde nicht gefunden. Etephon war erheblich wirksamer als die anderen verwendeten Substanzen: Alar, NC 9634, PP 413 und Morphaktin 7311. Alar verursachte eine- Verkürzung der Triebe, ohne die Zahl der Nodi zu verändern. pp 413 hatte keine Wirkung, während Morphaktin und NC 9634 das Wachstum teilweise hemmten. Etephon wirkte weitaus nachhaltiger und gleichförmiger als wiederholtes Gipfeln in Handarbeit.
