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.

VIGOUR MECHANISMS IN DWARFING ROOTSTOCKS FOR TEMPERATE FRUIT TREES

Acta Horticulturae, 2004
Dwarfing rootstocks have been widely used in the culture of apple and pear trees for a very long time. However, there is till almost no understanding of the plant mechanisms responsible for the dwarfing effect on the scion. The article first considers how the dwarfing effect is manifested in the scion’s growth.

Vigour reduction in girdled peach trees is related to lower midday stem water potentials

Functional Plant Biology, 2014
Stem or trunk girdling is a technique used in physiological studies and in horticultural practice for interrupting carbon flow through the phloem to other parts of the plant without influencing water flow in the xylem. Trunk girdling in peaches is practiced primarily to stimulate fruit growth but it also tends to decrease shoot vigour for a period of ...

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

Allelopathic Effects of Trees on Crop Seed Germination and Seedling Vigour-An Overview

Indian Journal of Forestry, 2000
The studies carried out by various workers show the presence of phytotoxins in tropical Multipurpose trees. Suggestions for taking up further studies on their allelopathic effects have been made for reducing adverse allelopathic effects on associated weed and crop species.

VIGOUR CONTROL OF THE OLIVE TREE IN A HIGH DENSITY PLANTING SYSTEM: TWO EXPERIMENTAL APPROACHES

Acta Horticulturae, 2011
In France, high density planting of olive orchards is progressively increasing. With this new training system tree vigour needs to be controlled. Both research and experimental organizations aim to help growers optimize the use of this system, by improving the management of existing orchards (better tree management, optimiza-tion of pruning, reduction ...

Tree vigour and the susceptibility of Douglas fir to Armillaria root disease

European Journal of Forest Pathology, 1998
SummaryIn this study the effects of thinning, fertilization and pruning on the vigour of Douglas fir (Pseudotsuga menziesii) and its susceptibility to Armillaria root disease were explored. Tree vigour was defined as the relative capacity for tree growth, expressed as the above‐ground biomass increment per unit of photosynthetic tissue, or growth ...
