The present research had the objective of studying the trunk diameter, the phenology and the bud production in 'Aurora-1' peach trees, budded on 'Okinawa' rootstock propagated by seeds and herbaceous cuttings, in three spacings (6 x 2 m, 6 x 3 m and 6 x 4 m). In 2nd and 3rd year after the planting seedlings (2005 and 2006, respectively), 13 variables were studied related to phenology and bud production in 'Aurora-1' peach tree, beyond seven quarterly diameter trunk evaluations, measured 5 cm above and below of bud point. In the adopted experimental conditions, it was concluded that: a) the trunck diameter of 'Aurora-1' peach trees is neither influenced by propagation method of 'Okinawa' rootstock nor by different in-row spacing; b) there are no differences on trunk diameter between measurements done above and below of bud point and no visible incompatibility symptoms with 'Aurora-1' scion was noticed, in both rootstock propagations methods; c) the studied propagations methods of 'Okinawa' rootstock do not affect the phenology, length of mixed branches, vegetative buds and flower buds production and its relation evaluated in 'Aurora-1' scion; d) the different studied spaces did not influence the phenology, the length of mixed branches and the number of flower buds production per branch of 'Aurora-1' scion.
