Tendrils of several Vitis species and hybrids were transformed into inflorescences by repeated treatment of shoot apices with 6-(benzylamino)-9-(2-tetrahydropyranyl)-9H-purine (PBA, 50-1000 flM). Tendrils of male vines were more readily converted into inflorescences by PBA-treatment than those of females or hermaphrodite vines. V. vinifera, V. rupestris and their hybrids were more responsive to PBA-treatment than V. monticola, V. girdiana and Muscadinia rotundifolia. Bunches of gmpes with viable seeds were produced by tendril-derived inflorescences of the V. vinifera cultivars Muscat of Alexandria (☿) and Katakourgan (♀) and of a V. vinifera X V. rupestris hybrid (♂).
Die Blütenbildung bei der Rebe: Der Einfluß des Genotyps auf die Cytokinin-induzierte
Umwandlung von Ranken in Infloreszenzen
Die Ranken verschiedener Vitis-Arten und -Bastarde entwickelten sich zu Infloreszenzen, wenn die Triebspitzen wiederholt mit 6-(Benzylamino)-9-(2-tetrahydropyranyl)-9H-purin (PBA; 50-1000 pM) behandelt wurden. Die Ranken männlicher Reben ließen sich durch PBA-Behandlung leichter in Infloreszenzen umwandeln als diejenigen weiblicher oder zwittriger Reben. V. vinifera, V. rupestris und ihre Kreuzungen reagierten stärker auf die PBA-Behandlung als V. monticola, V. girdiana und Muscadinia rotundifolia. Trauben mit lebensfähigen Samen entstanden aus rankenbürtigen Infloreszenzen der V.-vinifera-Sorten Muskat von Alexandria,(☿) und Katakourgan (♀) sowie einer V.-vinifera- x V.-rupestris-Kreuzung (♂).
