dc.description.abstractTillering capacity of wheat is highly influenced by environmental conditions and management practices. This research had as objective to evaluate tiller emission, survival and contribution to grain final yield affected by increasing sowing densities and growth regulators application in wheat. The experiment was conducted under completely randomized block design, with subdivided plots and four replications. Treatments consisted of four plant densities (30, 50, 70 and 90 plants m(-1)) combined with the application of growth regulators [control, (IBA+GA+KT), Trinexapac-Ethyl and (IBA+GA+KT) + Trinexapac-Ethyl]. Tiller emission, contribution to dry matter accumulation and grain yield, survival and yield potential in relation to the main stem were evaluated, as well as yield components and grain final yield. The application plant growth regulators did not affect tiller emission or any other yield parameters related to the main stem. Increasing plant densities reduced tiller emission and dry matter accumulation, which led to lower tiller contribution and yield potential. Reduced plant densities increased grain yield due to higher grain number and mass per ear, making up for lower number of ears per area.en
