Abstract: The objective of this study was to investigate the effect of different rates of ethephon on return bloom and yield, and fruit quality of 'Fuji' apple trees. The experiment was performed during the 2014/2015 and 2015/2016 growing seasons. Eighteen-year-old Fuji Standard apple trees grafted on M.9 were sprayed with different rates of ethephon (300 mg L -1 , 400 mg L -1 , and 500 mg L -1 ) 30 days after full bloom (DAFB) and compared to an unsprayed control. Yield components (number of fruit per tree, yield, frui… Show more

“…Such discrepancy could be further related to a light pruning performed in the previous winter (Zanotelli et al, 2013). Such management is performed to counteract the well-known alternate bearing behaviour of the Fuji apple, which causes a substantial drop in yield following a high yielding year (Belleggia et al, 2009;Atay et al, 2013;Pasa et al, 2021). In consequence to the light pruning, a larger amount of vegetative and flower buds remained on the tree leading to a higher yield and, possibly explaining the larger discrepancy between relatively high observed LAI and relatively low simulated values.…”

“…The discrepancy between the low simulated LAI and the high observed LAI in 2011 could have been further exacerbated by a lighter pruning performed in the previous winter compared to other years (Zanotelli et al, 2013). Such practice is sometimes performed in an attempt to counteract the strong alternate bearing behaviour of the Fuji variety, which causes a substantial drop in yield following a high yielding year (Belleggia et al, 2010;Atay et al, 2013;Pasa et al, 2021). As a consequence of the light pruning, a larger num- ber of vegetative and flower buds remained on the tree, leading to more growth and possibly contributing to the larger discrepancy between relatively high observed LAI and relatively low simulated LAI.…”
