Abstract
This thesis is the first published record of strigolactone identification in grapes. Strigolactones have recently been identified as critical third party (in addition to auxin and cytokinin) in the process of apical dominance. Visual differences in frequency and degree of lateral branching among several Vitis vinifera cultivars were observed, the native concentration of strigolactones in their xylem sap as well as that of two other Vitis species commonly used for rootstocks were measured. All of the tested plants produced the same five strigolactones (sorgolactone, solanacol, 7-oxoorobanchol, 7- hydroxyorbanchol acetate and didehydroorobanchol/didehydrostrigol). A series of experiments examining the effect of application of the synthetic strigolactone GR 24 to the lateral buds of these cultivars was also undertaken; the results do not indicate that GR24 application is especially promising on a larger horticultural scale as it did not restrain lateral outgrowth but did cause localized cambial thickening at the application site
