The aims of this study were first to determine the possible gibberellins biosynthetic pathway operated in the leaves of kohlrabi seedlings. Twelve gibberellins (GAs) were first identified and quantified in extracts of corm of the different skin colors of kohlrabi, Brassica oleracea var. gongylodes L. by GC-MS-SIM and Kovats retention indices. Six of these gibberellins are members of the early-C13-hydroxylation pathway (GA53, GA44, GA19, GA20, GA8, and GA1), and six are members of the non-C13-hydroxylation pathway (GA15, GA24, GA9, GA7, GA36, and GA4). Consequently, major gibberellin biosynthetic pathway operated in the leaves of kohlrabi seedlings was quantitatively an early C-13 hydroxylation route.

Key words: Kohlrabi, leaves, gibberellins, biosynthetic pathway.
