Primary crown gall tumours induced on stems on tomato plants by Agrobacterium tumefaciens yielded extracts with pronounced cytokinin activity. By mass spectrometry and other methods, 6-benzylaminopurine and its 9-β-ribofuranoside were identified as cytokinins in the extracts which also contained a 9-hexoside of 6-benzylaminopurine.
