Tendrils produced from shoot tips of grapevine (Vitis vinifera L.) cultured in vitro on Nitsch's medium developed into inflorescences when 5 to 10 uM benzylandenine (BA) OR 6-(Benzylamino)-9-(2-tetrahydropyranyl)-9H-purine (PBA)were applied directly to the tendril tips. Inflorescences did not form on tendrils if the cytokinins were supplied in the agar. Tendrils cultured in agitated liquid containing BAS, PBA, or zeatin riboside showed showed profuse branching and tendrils were transformed into inflorescences. Calyx and corolla (calyptra) stamens and pistils developed normaly in the presence of both zeatin riboside and PBA, but micro- and macrosporogenesis were absent. Inflorescences were formed by tendrils from five cultivars (Muscat of Alexandrina, Shiraz, Carbernet Sauvignon, Wortley Hall, and Sultana syn. Thomson Seedless) and also on tendrils from 12- to 15-week-old-seedlings. |
