Strategies to control tree vigour and optimise fruit production in 'Conference' pears [PDF]

open access: yesActa Horticulturae, 2008
The ban on the use of chlormequat (CCC) in pear orchards in 2001 forced Dutch pear growers to look for alternative methods to control tree vigour and stimulate flower bud development and fruit production.

Inheritance of Vigour Tree in F1 Apple Interspecific Hybrids

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2009
In ornamental apple breeding process, the vigour of the tree is an important characteristic, this trait being analyzed in selection of seminal descendants obtained by hybridization. The vigour of the apple trees was studied in 25 interspecific hybrids F1

Tree vigour, cropping, and phenology of sweet cherries in two systems of tree training on dwarf rootstocks [PDF]

open access: yesHorticultural Science, 2010
Five cultivars and four rootstocks (Gisela 5, P-HL-A, P-HL-B, and Tabel Edabriz) were evaluated on trees in fruiting stage trained like spindle and on trellis. Tree vigour was significantly related to cultivar, rootstock and to tree training.

High-density ‘Spadona’ pear orchard shows reduced tree sensitivity to fire blight damage due to decreased tree vigour

open access: yesPhytopathologia Mediterranea, 2021
Fire blight, caused by Erwinia amylovora, is a severe disease of pear (Pyrus communis). Highly vigorous trees are more sensitive to E. amylovora damage after summer pruning. Trees grown in high-density orchards have lower vigour than those in low-density

Windthrow causes declines in carbohydrate and phenolic concentrations and increased monoterpene emission in Norway spruce. [PDF]

open access: yesPLoS ONE
With the increasing frequencies of extreme weather events caused by climate change, the risk of forest damage from insect attacks grows. Storms and droughts can damage and weaken trees, reduce tree vigour and defence capacity and thus provide host trees ...

Dehydrogenaze polymorphism as a tool for early selection of low vigour rootstock for sweet and sour cherry [PDF]

open access: yesJournal of Agricultural Sciences (Belgrade), 2017
The correlation of dehydrogenase isoenzyme profile with plant/tree vigour of twenty genotypes belonging to the genus Prunus and the subgenus Cerasus as well as to four commercial rootstocks (Colt, Gisela 5, Gisela 6 and MaxMa 14) was ...

Pruning terms and techniques affect vigour and flower formation of Ukrainian sweet cherry cultivars

open access: yesAdvances in Horticultural Science, 2023
Excessive tree vigour and late entrance into full production, inherent to sweet cherry trees, are major challenges in the intensive cultivation of this crop.

The influence of biofertilization on the vegetative growth, yielding and nutritional status of 'Sampion' apple trees in first years after planting

open access: yesHorticultural Science, 2023
The effects of biofertilizers on the growth, yielding, and nutritional status of apple trees (in comparison with the standard mineral fertilization) was evaluated in 3-years experiment (2018-2020).

Tree vigour influences disease susceptibility of 'Hass' avocado fruits [PDF]

open access: yesAustralasian Plant Pathology, 2004
Differences in tree vigour as a result of feeder root destruction by Phytophthora cinnamomi were found to significantly (P < 0.05) influence disease susceptibility, fruit ripening rates and fruit size of ‘Hass’ avocado. Fruits from root rot-affected, non-vigorous trees had less anthracnose and took longer to ripen.

Using longitudinal survival probabilities to test field vigour estimates in sugar maple (Acer saccharum Marsh.) [PDF]

open access: yes, 2008
Tree mortality is a major force driving forest dynamics. To foresters, however, tree mortality is often considered a loss in productivity. To reduce tree mortality, silvicultural systems, such as selection cuts, aim at removing trees that are more likely
