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

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 ...

Individual tree variation and selection for yield and vigour : Experience from Côte d'Ivoire

, 2005
This study entailed a comparison of the performances of 22 single trees selected in a progeny trial in Bingerville (south-eastern Côte d'Ivoire) with those of the clones issued from their vegetative multiplication (plagiotropic cuttings), evaluated in a clonal trial at the same locality.

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 ...

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.

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

THE RELATIONSHIP OF ROOT GROWTH AND TREE VIGOUR FOLLOWING TRANSPLANTING

Arboricultural Journal, 1987
Summary Soil characteristics have a major influence on root growth and development. On dense soils, such as those found on many urban sites, root systems are very shallow and widespread. Less than 5 percent of the root system is typically transplanted with the tree. Replacement roots originate from the callus formed near the cut surface. Initially many

Manipulation of vigour in tropical fruit trees

2015
In recent years, growers of temperate tree crops have successfully adopted closer planting systems and smaller trees to achieve earlier cropping, high regular yields and improved management but in tropical fruit production such systems remain largely unexploited.
