“…Shading after harvest, however, had no significant effect on the number of flowers per shoot or flower cluster position. The position of flowers on shoots in unshaded vines was consistent with earlier reports (Tiyayon & Strik, 2003). Shading in 1998 had no effect on flowers or clusters per shoot originating from spurs in 1999 (data not shown).…”

The effect of overhead shading on yield, fruit quality, and subsequent flowering was studied in 4-year-old Actinidia arguta 'Ananasnaya' vines in Oregon, United States in 1998 and 1999. Experimental vines were shaded to 45% of full sun from 14 July to 14 August, 14 July to 10 September (harvest date), or 10 September to 16 November, 1998. Control vines were not shaded. Shading treatments were not repeated in 1999. Fruit fresh and dry weight development followed a similar growth pattern in all treatments. Shading had no effect on yield per vine or fruit fresh weight, length, diameter, and % soluble solids in 1998. Shading for 2 months before harvest significantly reduced fruit dry weight in 1998. Shading in 1998 did not affect percentage of budbreak or the number of buds, shoots, or fruitful shoots per vine in 1999. However, vines that were shaded had a significantly lower percentage of fruitful shoots than unshaded vines, especially vines shaded for 2 months before harvest in 1998. Vines shaded for 2 months before harvest had 48% fewer flowers and thus less yield than unshaded vines. one more cluster per shoot distally (at node 12) than vines shaded for 1 or 2 months before harvest the previous year. There was no treatment effect on fruit fresh weight, dry weight, length, diameter, seed number, or % soluble solids of marketable fruit in 1999. Results show that overhead shading, as might occur with dense canopies, did not have a large impact on fruit quality or yield in the current season, but reduced yield the following season. Overhead shading for 2 months before fruit harvest, led to the greatest reduction in flower number the following season confirming that the period before fruit harvest is an important time for flower bud evocation in this species.

“…In contrast to the finding that wood age did not affect shoot length, diameter, internode length, and fruit number per shoot in kiwifruit (Tiyayon and Strik 2010), wood age at the point of cutting in olive trees strongly influenced shoot type and its vigor in subsequent growing seasons (Fig. 3).…”

“…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). 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).…”

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.
