“…Our results may differ from previous work due to differences in the amount and location of canopy pruning and/or differences in pruning season. Spiers et al (2002) found that heavy pruning increased early yield of rabbiteye blueberry compared with moderate pruning; however, our data clearly demonstrate the tendency of heavy pruning to significantly delay fruit harvest in 'Jewel'. Spiers et al (2002), however, hedged only portions of the canopy, and therefore the half of the plant that remained unpruned would not be affected by pruning and may have contributed to earlier yields.…”

“…However, the removal of inflorescence buds during winter pruning would decrease inflorescence bud number and therefore berry number the following growing season, potentially increasing berry weight. Spiers et al (2002) also found no differences in berry weight between severities of pruning, even though there were differences in yield. The authors speculated that the already high vigor of the cultivar studied was not increased by pruning, which may also explain the lack of pruning effects on berry weight in the highly vigorous 'Emerald'.…”

“…The intensity of pruning plays a role in yield of blueberry bushes. Heavy summer pruning decreased yield of rabbiteye blueberry compared with moderate and no pruning in Louisiana, but had no effect on fruit size (Spiers et al, 2002). Davies (1983) found moderate pruning, regardless of season, produced the highest yields compared with heavy and nonpruned rabbiteye blueberries in Florida.…”

Blueberry (Vaccinium spp.) summer pruning can increase yield by promoting healthy fall foliage to support the reproductive development. However, there has been little research to examine the effects of timing and intensity of summer pruning in subtropical conditions. The objective of this study was to determine the effects of summer pruning timing and intensity on reproductive traits of mature ‘Jewel’ and ‘Emerald’ southern highbush blueberry (SHB) plants (V. corymbosum L. interspecific hybrid) in subtropical Florida. The effect of pruning time was evaluated by removing 30% of the canopy in June or July. The effect of intensity was evaluated by pruning either 30% or 60% of the canopy in June, followed by removal of the upper 5 cm of regrowth (“tipping”) in July. Both timing and intensity used nonpruned plants as a control. The same plants were evaluated over three consecutive seasons (June 2011–May 2014). Main effects of pruning time, intensity, and tipping were evaluated. Tipping did not affect the reproductive traits evaluated. ‘Emerald’ reproductive traits were unaffected by either summer pruning time or intensity over the 3-year study. ‘Jewel’ yield was unaffected in the first year, but was increased by 48% and 65% in years 2 and 3, respectively, in the 30% pruning treatment compared with the nonpruned control. Lack of pruning in ‘Jewel’ decreased inflorescence bud number compared with moderate pruning likely due to more diseased foliage that increased defoliation. Thus, pruning effects on reproductive traits were cultivar dependent. Leaving ‘Jewel’ plants unpruned for two or more seasons reduced inflorescence bud number and yield.

“…(PESCiE et al, 2011). However, Spiers et al (2002) affirm that the removal of up to 25% of the upper part of the branches can be carried out without reducing fruit yield. This diversity of results among the studies cited above suggests that, for the definition of pruning intensity, several factors, among them cultivars, must be taken into account.…”

-The objective of this study was to evaluate the effect of pruning intensity on yield and quality of blueberries fruits. It was evaluated the cultivar Misty. The treatments were: absence of pruning; light pruning; regular pruning and drastic pruning. The experimental design was randomized blocks with four replications. The variables analyzed were fruit production, fruit size, pH, total soluble solids (TSS) and total titratable acidity (TTA), and the bioactive compounds such as phenolic compounds, anthocyanins and antioxidant activity. The plants that received drastic pruning showed higher averages of production and fruit size. The highest concentrations of phytochemical compounds in blueberry fruits occurred as pruning was more drastic. The use of different intensity of pruning can modify the productive behavior and postharvest quality of fruits. Index terms -Vaccinium, cultural practices, fruit quality, functional. PRODUÇÃO, QUALIDADE FÍSICO-QUÍMICA E COMPOSTOS BIOATIVOS DE FRUTOS DE MIRTILEIRO MISTY SOB DIFERENTES INTENSIDADES DE PODARESUMO -O objetivo do presente trabalho foi avaliar o efeito de intensidades de poda na produção e na qualidade dos frutos de mirtileiro. O material vegetal utilizado foi mirtileiro da cultivar Misty. O fator estudado foi poda, em diferentes intensidades: sem poda; poda leve; poda-testemunha e poda drástica. O delineamento experimental foi em blocos ao acaso, com 4 repetições. Foram avaliadas a produção total de frutos, o tamanho de frutos, as características fisico-químicas como: pH, teor de sólidos solúveis totais (SST) e acidez total titulável (ATT), os compostos bioativos como: compostos fenólicos, antocianinas totais e atividade antioxidante. As plantas que receberam poda drástica apresentaram maiores médias em produção e tamanho de frutos. As maiores concentrações de compostos fitoquímicos no mirtilo ocorreram à medida que a poda foi mais drástica. O uso de diferentes intensidades de poda pode modificar o comportamento produtivo e a qualidade pós-colheita dos frutos. Termos para indexação: Vaccinium, manejo, qualidade de fruto, funcionais. 1(Paper 010-16).
