The reasons for tiller absence and/or low survival were studied by analyzing vascular connections between tiller and other plant parts. Experiments were conducted on open air and growth chamber conditions with the wheat genotypes, IPF- 49865 (uniculm), EMBRAPA-16 and BR-23 (multiculm); oats, UFRGS-10 and UFRGS-15; and barley, FM-519. Analyses were made on main culm and primary tiller foliar development, number of primary and secondary tillers and vascularization and tiller vascular connection with the rest of the plants. Vascular connections did not explain tillering inhibition since all tillers were vascularly connected to the plant.
