“…Summer pruning of peach are com-monly said to have many advantages over dormant pruning, including control of tree size and shape, im-proved light distribution in tree canopy, advantages fruit maturity, compressed harvest period, improved fruit size and color, improved flower bud cold hardiness, reduced pruning expenses, and suppressed tree vigor (Marini and Barden, 1987). This study was conducted to compare the effects of dormant pruning, preharvest summer pruning and post harvest summer pruning on shoot growth, yield, fruit quality, and carbohydrate levels of two peach cultivars.…”

Mature "Earlyred" and Glohaven" peach [Prunus persica (L.) Batsch] trees on peach seedling rootstocks were dormant and summer pruned (June, July, August and September). Average shoot length was lower in the second year than in first year; whereas, shoot diameter was higher in the second year than in first year. Summer pruning treatments reduced shoot growth, but increased shoot diameter. Generally, the control and dormant pruned trees had the highest trunk cross-sectional area (TCSA) increment and yield efficiency (yield per trunk cross-sectional area). Summer pruned trees had a higher average fruit weight and soluble solids content than dormant pruned or control trees but at the two experimental years, fruit acidity showed no consistent response to pruning treatments. Dormant and summer pruning treatments had different effects on carbohydrate contents of peach trees. Generally, control and dormant pruned trees had higher carbohydrate content than summer pruned trees. Earlier summer pruning (June or July) lowered carbohydrate content more than late summer pruning.

“…Summer pruning of extended and vigorous shoots has been an effective tool to improve light penetration and distribution within the tree canopy [37,38], which can enhance fruit quality in apple trees [39], and is regarded as an ecological alternative to decrease bitter pit incidence during the storage of high quality apple cv. 'Reinette du Canada' [7].…”

Effect of Sustainable Preharvest and Postharvest Techniques on Quality and Storability of High-Acidity ‘Reinette du Canada’ Apple

Consumers are more disposed towards paying price premiums for sustainable food products. This fact is especially important for products with a PDO (Protected Designation of Origin) label, such as the high-acidity apple cultivar ‘Reinette du Canada’. However, ‘Reinette du Canada’ apple fruit is affected by two of the main post-harvest disorders in apple cultivars, bitter pit and senescent breakdown. As a means to achieve sustainable production of this high-quality apple cultivar, the effect of a sustainable preharvest technique, summer pruning, in combination with a zero-residue postharvest treatment allowed in organic farming on calcium-related disorders and quality in global terms in this PDO-labelled apple cultivar was assessed during storage. The combination of the two sustainable practices was an effective tool in diminishing senescent breakdown from 43% to 17% and to decrease bitter pit incidence by up to 21% (from 36% to 15%) throughout storage, especially in fruit with high susceptibility to this disorder during storage. Moreover, the overall acceptability was kept high (values of more than 3 on a 5-point scale) when applying this environment-friendly sustainable horticulture practice, which will not only reduce the synthetic pesticide input in the apple agroecosystem, but also contribute to producing fruit with zero residues.

“…Pruning may be defined as the removal of plant parts to achieve a desirable architecture of the canopy and also using the foliage density by removing the unproductive branches of fruit trees. Summer pruning in apple orchards can be traced back to the 17th century and has scientific attention since 1903 (Marini and Barden, 1987). For vigour control, pruning is the most important operation conducted in dormant season, when the leaf fall takes place.…”

Pruning has been practiced for ages in controlling tree size because it has much less stimulating effect on shoot re-growth. The pruning is done to restrict excessive vegetative growth and to maintain a balance between leaf/fruit ratio, fruit size, fruit colour and other quality attributes. Excessive tree vigour can reduce flower bud formation, fruit set and result in reduced fruit quality. Summer pruning by removing the vigorous growing shoots increase the light intensity in cropping zone and colour intensity. Late summer pruning also reduce the growth due to reduction in photosynthetic capacity and ultimately carbohydrate reserve by reducing the leaf area index and the spread of the canopy.
