“…Effect of pruning was also verified by Radünz et al (2014), but only in some cultivars. On the other hand, the mean pH value observed in the present study is in agreement with the one found by Molina et al (2008) for the same cultivar, which found an average of 2.80.…”

“…The antioxidant and nutraceutical potential in the blueberry can be influenced by the pruning severity in the plants, mainly with impact on the production and effects of the increase of the incident solar radiation on the fruits (RADÜNz et al, 2014).…”

“…Increased yield and leaf reduction may have resulted in a lower accumulation of TSS. Radünz et al (2014) emphasizes that the pruning intensity modifies the production, a factor that could modify the TSS content in blueberry fruits. The TSS mean is also in accordance with Molina et al (2008) who stated that the cultivar Misty presents 12.7 o Brix.…”

“…One hypothesis, for the lowest acidity, is the greater competition for nutrients between the vegetative and the productive part. Possibly genetic factors are related, since Radünz et al (2014) verified effects of pruning intensity only in some cultivars.…”

-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).

-Low genetic diversity of citrus scion and rootstock cultivars makes the crop more vulnerable to diseases and pests. The objective of this study was to evaluate the performance of 'Jaffa' sweet orange grafted onto five rootstocks over six harvests in subtropical conditions in the north of Paraná state, Brazil. The experiment used a randomized block design, with six replications and two trees per plot, spaced at 7.0 m x 4.0 m. The rootstocks were: 'Rangpur' lime, 'Cleopatra' and 'Sunki' mandarins, 'Fepagro C-13' citrange, and 'Swingle' citrumelo. The variables evaluated were vigor, yield, and yield efficiency of the trees as well as the physical and chemical characteristics of the fruits. Data were subjected to analysis of variance, complemented by Scott-Knott test at 5% probability. The smallest tree canopy for 'Jaffa' sweet orange plants was induced by the 'Rangpur' lime rootstock. The trees had the same cumulative yield performance over six seasons for all rootstocks. The best yield efficiency for 'Jaffa' sweet orange trees was provided by 'Fepagro C-13' citrange rootstock. With regard to fruit quality, no differences were observed among the rootstocks and the 'Jaffa' sweet orange fruits met the standards required by the fresh fruit market and the fruit processing industry.
