Abstract:

This experiment was conducted in the pine woods of central Europe at a research area established in 1951. The experimental area of 1.35 ha was set up in a 14-year-old pine tree stand, which was divided into lots, and the pruning procedure took place in different variants. Some lots constituted control lots without pruned trees. The trees were pruned in four variants, reducing the living tree crown by 1/4, 1/3, 1/2, and 2/3 of its length. The study’s main aim was to determine the influence of pruning forest trees on the tree tissue. Moreover, the study attempted to answer whether pruning was a

Abstract:

Jatropha (Jatropha curcas, L.) is an energy crop mainly cultivated for the oil-seed, and the oil is usually used as bio-fuel. However, few studies have reported information about the utilization of the wood as a fuel for boiler heating systems. With 2500 jatropha trees per hectare, it is possible to produce about 3 t·ha−1·y−1 of woody biomass from pruning. In addition, jatropha trees are commonly cut down to a height of 45 cm once every 10 years, with a production of 80 t·ha−1 of dry matter of woody biomass. The use of this biomass has not yet been investigated. During the European project Jat

Wood removal from temporary trees was low, except for the last two years of the study, and little difference in yield and quality from the control was obtained. Top and side hedging reduced overall yield of ‘Desirable’ and ‘Farley’ and it changed the alternate bearing phase of ‘Elliott’ so that yields were increased and decrease

Abstract Once site and genetic stock are selected, management of stocking, rotation age, and pruning are the principal means available to foresters to affect wood quality and value in stands of coast Douglas-fir (Pseudotsuga menziesii var menziesii).

This analysis showed in general that improving quality through high levels of stocking or extending rotations were costly ways to improve wood quality while pruning was a cost-effective way to improve wood quali

Abstract In theory, pruning is an attractive silvicultural technique because there is a great potential for increased production of clear wood after its execution. Much of the currently available literature on the pruning of Douglas-fir (Pseudotsuga menziesii) concerns the effects of pruning on diameter and height growth. Other aspects of the pruning response need to be considered, because clear wood production cannot be guaranteed merely because the trees were pruned.

Abstract Two-year-old peach trees [Prunus persica (L.) Batsch cv. Candor] on ‘Lovell’ rootstock were summer-pruned (selective thinning and heading of current season's growth) 23 days before harvest. Pruning did not affect fruit quality. Summer pruning increased yield the subsequent year, apparently by increasing fruiting wood in the center of the tree. Summer pruning vigorous 3-year-old ‘Loring’ peach trees 8 weeks before harvest increased PAR through the canopy, 1 m above the ground, immediately after pruning and when measured at harvest. Fruit from summer-pruned ‘Loring’ were firmer, with lo

Trunk cincturing at monthly intervals from budbreak to mid January had no significant effects on vegetative flushing or flowering of 6-year-old custard apple trees (Annona cheriinola x Annona squamosa) cv. Pink's Mammoth in subtropical Queensland. In contrast, pre-budbreak defoliation with 1.0 g/L of 2- chloroethyi-phosphonic acid and 250 g/L of urea hastened, and post-budbreak defoliation and summer pruning delayed, shoot growth and flowering in 3-yearold custard apple trees, cv.

Cuttings were dipped in a Trichoderma suspension either before or after callusing. Pre-callusing dips were carried out for 3 years and yielded contradictory results. By contrast, post-callusing Trichoderma dips led to significant growth of hairy roots and a reduction in the longitudinal discolorations caused by P. chlamydospora inoculated into the rootstock after dipping.

In the European Union (EU), a total of 11,301,345 hectares are dedicated to the cultivation of fruit trees, mainly olive orchards, grapevines, nut trees (almond, walnut, chestnut, hazelnut, and pistachio), apple and pear trees, stone fruit trees (peach, nectarine, apricot, cherry, and plum), and citrus fruit trees (orange, clementine, satsuma, mandarin, lemon, grapefruit, and pomelo). Pruning these trees, together with plantation removal to a lesser extent, produces a huge amount of wood waste.

Pruning wood mass is crucial for grapevine management, as it reflects the vine’s vigor and balance. However, traditional manual measurement methods are time-consuming and labor-intensive.

This study assesses the use of image analysis for estimating wood weight, focusing on image acquisition conditions.

Western larch (Larix occidentalis Nutt.) trees in western Montana, U.S.A., were monitored for 6 years following pruning to assess incidence of epicormic sprouting. Trees were pruned to either 2.4 or 5.5 m. Epicormic sprouts were more prevalent in smaller diameter trees and in trees pruned to shorter live crown lengths than larger or longer crowned trees. Number of sprouts declined since pruning, but over 30% of trees still had epicormic sprouts 6 years after pruning. Sprouts that did not extend from the bole were prone to becoming dormant or dying over time. Extended sprouts were more persiste

It was clear that a height of 3 m or more is adequate for pigeonpea to receive its first cut with only 10% stool mortalities. Cutting the primary shoot at 8 MAP (in the dry season) ensured greater stump survival and also stimulated rapid coppice shoot r
