In mild winter climates, the budbreak promoters application is one of main
management strategies used to decrease problems of insufficient winter chilling on
temperate fruit trees. Despite of the high efficiency of some chemicals on budbreak
induction, the high toxicity showed by these compounds is one problem related to its
use. Erger, an organic nitrogen compound, combined with calcium nitrate, has a
similar effect to that of hydrogen cyanamid, with the advantage of being less
dangerous to the environment. The objective of this study was to evaluate the effects
of Erger and calcium nitrate combinations on budbreak induction of ?Imperial
Gala? and ?Suprema?s Fuji? apples. The experiments were carried out in Caçador,
Santa Catarina, Brazil (26°46?S, 51°W), at 960 m a.s.l., during two growing seasons
(2006/2007 and 2007/2008). The treatments tested were control, standard (mineral
oil 3% + Dormex® 0.7%), and Erger + calcium nitrate at concentrations of 3, 5, and
7%. Full bloom date, axillary and terminal budbreak, fruit set, and mean fruit
weight were evaluated. All Erger + calcium nitrate concentrations anticipated the
full bloom date in relation to control treatment, but were not observed differences
with mineral oil 3% and Dormex® 0.7%. The budbreak promoters increased
significantly axillary and terminal budbreak and increasing the uniformity of
budbreak. Fruit set was not affected by Erger + calcium nitrate concentration in
relation standard treatment. The combinations of Erger and calcium nitrate showed
similar uniformity and performance to mineral oil and hydrogen cyanamide on
budbreak, showing to be an efficient alternative to budbreak induction in ?Imperial
Gala? and ?Suprema?s Fuji? apples MenosIn mild winter climates, the budbreak promoters application is one of main
