“…2). High demand for limited carbohydrate and nutrients reserves (as CWC stimulates here) decreases fruit set [Breen et al 2015, Stanley 2016. These superior results for fruit set in Weak-CWC might be addressed on tree nutritional status (especially nitrogen) accumulated in the previous year.…”

Crop-weed competition (CWC) for water and nutrients can negatively affect orchard performance, especially in high-density apple orchards. With this study, we compared the effects of three CWC levels: Weak, Moderate, and Strong for the orchard performance of apple in the Mediterranean area. The study was conducted at a 'Golden Delicious'/M.9 orchard in a high-density formation (3.5 × 1 m spacing). Cumulative yield was greatest in Weak-CWC, and it decreased as CWC increased. Overall, Weak-CWC performed remarkable results for successful apple production under Mediterranean conditions.

“…Therefore, thinning strategies may be fine-tuned, modulating thinning intensity in different part of the canopy and reducing the presence of fruits in the distal portion of 1-year old shoot and in the internal part of the tree. An early thinning, after an adequate fruit set, could regulate fruit fresh weight in apricot, possibly affecting the mechanism of assimilate transport between sources and sinks (Stanley, 2016).…”

“…These observations suggest that the source-sink ratio should not be considered at the tree level, as diverse positions into the canopy can differentially regulate growth, for example, interacting with light or type of bearing structure. On the other side, results allow to develop more targeted orchard practices such as pruning or training system, favoring the presence of more efficient bearing structures, depending on the species, e.g., older wood (2-3 years) in apricot (Stanley, 2016).…”

“…Although practical field experience in many fruit trees suggests that shoot elongation often increases with wood age at the cutting points, a few studies have experimentally evaluated the effect of wood age on shoot demography and reproductive characteristics (Lauri et al 1996;Tiyayon and Strik 2010;Stanley 2016). Interestingly, experimental evidence in kiwifruit found that neither shoot length nor fruit number differed with wood age after summer pruning (Tiyayon and Strik 2010).…”

“…Interestingly, experimental evidence in kiwifruit found that neither shoot length nor fruit number differed with wood age after summer pruning (Tiyayon and Strik 2010). In studies with several apple and apricot cultivars, fruit set was lower in shoots on 1-yearold wood than on 2-or 3-year-old wood (Lauri et al 1996;Stanley 2016), but older wood also tended to show low fruit set in apricot (Stanley 2016). To the best of our knowledge, the effect of wood age on the subsequent shoot demography and reproductive characteristics after winter and summer mechancial pruning of olive trees has not been previously examined.…”

Key message More vigorous watersprouts and fewer low vigor shoots form as wood age increases at the cutting points with greater canopy pruning depth in olive trees, which reduces return flowering. Such information is relevant to long-term olive orchard pruning strategies in hedgerows. Abstract Demographic analysis of growth responses to pruning in fruit trees seeks the quantification of the typology of new shoots originating from the remaining branches. Pruning of hedgerows using mechanical discs is becoming increasingly common in orchards, but little information is available as to how such pruning, which does not discriminate between branch size, wood age at the cutting point, branch type, or position, modifies subsequent new shoot demography. Hence, the experiment described in this study in young olive trees (cv. Arbequina) assessed the following questions: (1) Is the type and growth of new shoots associated with the intensity of mechanical pruning and/or the wood age on which they grow? (2) How many growing seasons does it take for new shoots formed after pruning to flower? The principal hypothesis was that a greater proportion of vigorous watersprouts form compared to low vigor shoots as wood age at the cutting points increases with canopy pruning depth, and that the watersprouts have low flowering potential. Both new shoot growth and return flowering were monitored on exposed supporting wood over several growing seasons after implementing three winter (25W, 50W, and 75W) pruning levels of increasing intensity and one summer pruning (75S) treatment along with an unpruned control (CON). As hypothesized, a greater number and elongation of vigorous watersprouts were found as wood age increased at the cutting points with greater winter pruning intensity, and the watersprouts had low levels of return flowering even 3 full years after pruning compared to the CON. Growth of low vigor shoots was relatively more important than watersprout growth in the severe summer pruning treatment, although 3 years after the summer pruning flowering was not fully recovered. In contrast, the more lightly pruned winter treatments (25W, 50W) did not show significant differences in flowering with the CON at the end of 3 years. Thus, mechanical hedge pruning in olive trees should be light-to-moderate to avoid the formation of watersprouts on older wood, which leads to long-term reductions in flowering.
