Pre-disturbance tree size, sprouting vigour and competition drive the survival and growth of resprouting trees

Forest Ecology and Management, 2019
Abstract Forest trees of many species are able to recover from logging and other severe disturbances by resprouting. Due to rapid growth, sprouts often form a significant part of forest regeneration and are also a key component of coppice forests.

Variability of seedling vigour in Persian walnut as influenced by the vigour and bearing habit of the mother tree

The Journal of Horticultural Science and Biotechnology, 2009
SummaryObservations on dwarf and precocious (early maturing) seedlings of Persian walnut (Juglans regia L.) in nurseries, and the consistency of their growth under orchard conditions, encouraged us to study the genetic nature and variability of morphological traits related to seedling vigour.

Stem anatomical characters in relation to tree vigour in mango (Mangifera indica L.)

Scientia Horticulturae, 1992
Abstract Studies conducted with 24 mango cultivars of widely varying vigour indicated that low vigour of trees was associated with a higher primary phloem to primary xylem ratio in young shoots. Width of cortex or pith did not show any relationship with tree vigour. There was no significant difference among the cultivars with respect to the number of

A set of vegetative morphological variables to objectively estimate apple (Malus×domestica) tree orchard vigour

Scientia Horticulturae, 2005
Orchard vigour, defined as the intensity of vegetative growth, is an important indicator for crop management in fruit tree cropping systems. It is often evaluated in commercial plots by experts on a non-formalised basis or measured with a single variable known as trunk cross-sectional area (TCSA).

Size‐mediated ageing reduces vigour in trees

Ecology Letters, 2005
AbstractThere is increasing interest in understanding the costs and benefits of increased size and prolonged lifespan for plants. Some species of trees can grow more than 100 m in height and can live for several millennia, however whether these achievements are obtained at the cost of some other physiological functions is currently unclear.

Xylem manipulation techniques affecting tree vigour in peach and olive trees

Acta Horticulturae, 2018
Water relations are among the major factors affecting shoot growth and plant vegetative vigor. In many tree crops, dwarfing rootstocks regulate scion vegetative vigor by reducing plant hydraulic conductance. In Prunus spp. reduced xylem vessel size leads to reduced hydraulic conductance, but reduction of annual xylem tissue growth could have similar ...

Vigour and non-structural carbohydrates in young prune trees

Scientia Horticulturae, 1992
Abstract To determine if differences in vegetative vigour are related to carbon partitioning in trees, three rootstck clones (i.e. Marianna GF8.1, Ishtara® and St. Julien Pixy 2879), inducing vigorous or dwarfing graft combinations with two Prunus domestica L. scion genotypes, were studied. Three years after planting in the orchard, just before bud

Soil properties and tree vigour in the Goulburn Valley

Australian Journal of Experimental Agriculture and Animal Husbandry, 1966
A survey technique was used to correlate several field properties of soils with size of fruit trees in commercial orchards of the Goulbum Valley, Victoria. Where the surface soil was shallow (about 6 inches) its depth was the most important factor affecting tree size, but heaviness of the subsoil also had an effect.

The effect of rootstocks on mango tree vigour, scion architecture, yield, percentage of flowering terminals in young unpruned trees

Acta Horticulturae, 2022
In Australia, commercial tree size management in mango orchards involves annual machine hedging and heavy hand pruning. In tropical growing regions, heavy pruning often stimulates strong vegetative regrowth that is less likely to flower due to insufficient terminal growth-unit dormancy required for flowering.

Tree vigour and yield of plum grown under high density planting system

Acta Horticulturae, 2016
During the second through sixth growing seasons, under the environmental conditions of Cacak (Serbia), tree vigour, yield (kg tree-1 and t ha-1), yield efficiency, biennial bearing index and fruit weight were studied in five plum cultivars ('Cacanska Rana, 'Cacanska Lepotica', 'Cacanska Najbolja', 'Cacanska Rodna' and 'Stanley') grafted on myrobalan ...
