Increased boron concentrations of Scots pine foliage induced by green pruning

Canadian Journal of Forest Research, 2002
The responses of Scots pine (Pinus sylvestris L.) foliar boron (B) concentrations to artificial defoliation by green pruning were studied by examining sample trees for 3 years after the treatments. In winter, concentrations of boron in foliage were determined individually from needles on the lateral top shoots of 168 sample trees (at the beginning 2–8

Enhancement of Lignin Production from Olive Tree Pruning Integrated in a Green Biorefinery

Industrial & Engineering Chemistry Research, 2011
The green biorefinery concept relies on economically feasible processing to achieve a complete utilization of most lignocellulosic biomass components using green technologies. Among the main component of lignocellulosic biomass, lignin is one of the most interesting components since its aromatic nature makes lignin unique.

Quantitative assessment of fungal colonization in Norway spruce after green pruning

European Journal of Forest Pathology, 1997
SummaryIn July and in October of 1978, 1979, 1980 five Picea abies stands in Baden‐Württemberg, Germany were green‐pruned up to a tree height level of c. 10 m. In 1993–94, 30 pruned trees and five control trees from each stand were harvested for investigation.

Regulation of photosynthesis in Eucalyptus nitens (Deane and Maiden) Maiden following green pruning

Trees, 1998
&p.1: Green pruning was used to induce source limitation in 1-year-old Eucalyptus nitens (Deane and Maiden) Maiden plants in an investigation of regulation of net CO2 assimilation (A). The pruning regimes involved removal of 0, 50% or 70% of the length of green crown, equivalent to 0, 78% or 95% of leaf area respectively. Gas exchange measurements were

Aboveground biomass partitioning and crown architecture of Eucalyptus nitens following green pruning

Canadian Journal of Forest Research, 1998
The effects of green pruning on aboveground biomass partitioning and crown architecture were explored in a 3-year-old Eucalyptus nitens (Deane and Maiden) Maiden plantation. Responses were measured in five height zones and three foliage age classes over a 20-month period following removal of 0, 50, or 70% of the green crown length.

Influence of the green pruning treatments on Storgozia variety phenology

2022
The study was carried out in the period 2014-2020 in the Experimental Base of the Institute of Viticulture and Enology – Pleven. The influence of some green pruning treatments on the Storgozia variety phenology had been investigated. It was found there were no significant differences in the average timing of occurrence, mass manifestation and the end ...

Effects of green pruning on growth and stem shape of Eucalyptus nitens (Deane and Maiden) Maiden

New Forests, 1998
An experiment was established in two high quality Eucalyptus nitens Deane and Maiden (Maiden) plantations in Tasmania. At the start of the experiment the trees were three years old and the plantations were on the point of canopy closure. Selected trees were pruned to remove 0, 50% or 70% of the lower green crown length, and each was surrounded by eight

Nitrogen Release from Leaves and Prunings of Different Tree Species Used as Green Manures

Biological Agriculture & Horticulture, 1997
ABSTRACT A pot trial and an incubation trial were carried out simultaneously in a greenhouse to determine the effect of N, lignin and polyphenol contents of leaves and prunings of various decidious trees (Alnus incarta (L.) Moench, Alnus glutinosa (L.) Gaertn., Salix viminalis L., Populus trichocarpa Hook x Populus deltoides Marsh.) and white clover ...

Impact of summer green pruning on the phenolic content of grapes from Cabernet Franc cultivar

2023
Abstract A study was carried out on the phenolic content of Cabernet Franc grape cultivar depending on the applied summer green pruning operations. The research was conducted in a fruiting plantation and covered two consecutive harvests (2021–2022). The effects of bunch thinning and a combination of thinning and defoliation in the bunch area on total ...

Influence of green prunings on the dynamics of shoot growth in Storgozia variety

2023
Проучено е влиянието на някои зелени резитбени операции върху динамиката в растежа на летораслите при сорт Storgozia. Изследването е проведено в Експерименталната база на Институт по лозарство и винарство – Плевен през периода 2014-2020г. Приложени са зелените резитбени операции – кършене през юни и юли месец, прореждане на гроздовете и просветляване в
