“…However, moderate pruning significantly increased yield compared with the control, demonstrating the cumulative effect of slight, nonsignificant increases in individual yield components. The lack of effect of heavy pruning on yield in our study contrasts with previous work on 'Sharpblue' SHB (Williamson and Darnell, 1996) and rabbiteye blueberry (Austin and Bondari, 1989;Davies, 1983;Souza et al, 2014), where heavy pruning resulted in yield reduction. 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), 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. Souza et al (2014) found that winter hand pruning, regardless of intensity, resulted in earlier yields for rabbiteye blueberry compared with no pruning. Krewer et al (2004) showed that hedging resulted in delayed inflorescence bud development during the spring, which is linked to the time of inflorescence bud initiation (Kovaleski et al, 2015b).…”

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.

“…whereas, fruits of Briteblue presented higher levels of these compounds in plants derived from cutting. Finally, fruits harvested in plants without pruning or with light pruning presented higher antioxidant activity, independent of the studied cultivar (SOUZA et al, 2014).…”

The lack of an efficient method of propagation in some cultivars makes it difficult to expand the blueberry culture. In Brazil, we still do not produce seedlings with needed quality and quantity to improve the sector. The cloning of the selected material through mini propagation and micro propagation is an alternative to increase the multiplication and rooting capacity of the blueberries. Allied to this, the use of cultivation system without soil for the development of cloned material facilitates the seedlings production. In addition, we can keep matrices in small spaces with the use of mini-gardens and clonal micro-gardens controlling climatic and nutritional factors. In the Laboratory of Fruit Plants Propagation, of the Phytotechnology Department of the School of Agronomy Eliseu Maciel of the Federal University of Pelotas we have searching for more than ten years the micro propagation and the mini propagation allied to the clonal gardens kept in a protected place, reducing the physical space and improving phytosanitary control. The experiments carried out brought important information regarding to the vegetative propagation of the blueberry to improve the seedling production process for this species. In this way, researches that have been realized seek to generate knowledge about the best way of propagating and conducting this fruit.

“…(control, light and drastically) Em relação às variáveis apresentadas naTabela 5, a intensidade de poda influenciou apenas a acidez titulável de mirtileiros 'Briteblue', onde as plantas sem poda produziram frutos de maior acidez, comparadas às podadas. SOUZA et al (2014) verificaram que a acidez titulável foi influenciada pela prática da poda no ciclo 2011/2012.…”

“…A cor e os sólidos solúveis dos frutos 'Briteblue' foram influenciados pelos dois fatores estudados (Tabela 6), diferentemente do encontrado por SOUZA et al (2014), que verificaram que a prática de poda teve pouca influência sobre a qualidade dos frutos avaliados, onde o teor de sólidos solúveis não foi alterado nas condições do experimento. Outro estudo que também pode ser comparado, é o de JORQUERA-FONTENA et al (2014), onde a concentração total de sólidos solúveis nos frutos aumentou aproximadamente 9% em plantas podadas drasticamente.…”
