VIGOUR MECHANISMS IN DWARFING ROOTSTOCKS FOR TEMPERATE FRUIT TREES
Acta Horticulturae, 2004Dwarfing 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.

Allelopathic Effects of Trees on Crop Seed Germination and Seedling Vigour-An Overview
Indian Journal of Forestry, 2000The 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 reduction in girdled peach trees is related to lower midday stem water potentials
Functional Plant Biology, 2014Stem 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 ...

VIGOUR CONTROL OF THE OLIVE TREE IN A HIGH DENSITY PLANTING SYSTEM: TWO EXPERIMENTAL APPROACHES
Acta Horticulturae, 2011In 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, 1998SummaryIn 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 ...

Rootstock and interstock effects on deciduous fruit tree vigour, precocity, and yield productivity
New Zealand Journal of Crop and Horticultural Science, 1995Abstract Rootstocks have been used for propagating temperate fruit trees for more than 2000 years. Many of the rootstocks used, as well as providing a simple method of propagation, also affect scion growth, cropping, and adaptability to different environmental conditions.

The Kinetics of Tracheid Development in Tsuga canadensis Carr. and its Relation to Tree Vigour
Annals of Botany, 1972Cell counts from samples taken at weekly intervals, from 14 May to 22 October 1969, in a T. canadensis stand in Massachusetts, U.S.A., showed that the width of the annual ring was correlated with the rate of cell production and that only the least vigorous trees (c. 20 tracheids year") had a shorter growing season. The time required for completion of a
