High density planting systems are a prerequisite to economise the use of land and labour costs of orchards. Dwarfing rootstocks controlling the vigour of the scion cultivars form the basis for such orchards (Wertheim and Webster, 2005). In the Netherlands, rootstock research is limited to and focussed on testing rootstocks selected abroad. For the Dutch pear growers the main selection criteria ...

Grafting is a centuries-old technique used in plants to obtain economic benefits. Grafting increases nutrient uptake and utilization efficiency in a number of plant species, including fruits, vegetables, and ornamentals. Selected rootstocks of the same species or close relatives are utilized in grafting. Rootstocks absorb more water and ions than self-rooted plants and transport these water and...

Vitis vinifera scions are commonly grafted onto rootstocks of other grape species to influence scion vigour and provide resistance to soil-borne pests and abiotic stress; however, the mechanisms by which rootstocks affect scion physiology remain unknown. This study characterized the hydraulic physiology of Vitis rootstocks that vary in vigour classification by investigating aquaporin (VvPIP) ge...

Amplified fragment length polymorphism (AFLP) technique was used to assess genetic relationships among 20 grapevine rootstocks in Turkey. Discrimination of the rootstocks with 10 primer combinations yielded 1366 bands on AFLP gels; 65% of them were polymorphic. The rootstocks revealed two main clusters; one of them comprised two (Malégue and Harmony) and the other 18 genotypes. The Ber x Rip hy...

Most commercial apple orchards are established on either Marubakaido (Malus prunifolia Borkh.) (high vigor), M-9 pumila) (low or a combination of both rootstocks through the intergrafting technique. The Geneva® Series were developed as an alternative to modernization. vigor influences anatomical xylem formation and, therefore, canopy cultivar’s hydraulic conductivity. When affected by embolism,...

A research was conducted at Pistachio Research Institute in Rafsanjan, Iran, to evaluate the effects of P. vera L. ‘Badami’, P. vera L. ‘Sarakhs’ and P. mutica F and M. ‘Beneh’ rootstocks on mineral content of leaves and kernels of ‘Owhadi’, ‘Kalleh-ghuchi’ and ‘Ahamd-aghaii’ pistachio scion cultivars. Twenty year old trees of these combinations were used during study over 2003 and 2004. Leaves...

We studied relationships between diurnal patterns of stem water potential (PsiSTEM) and stem extension growth of the same scion cultivar growing on three rootstocks with differing size-controlling potentials. The peach trees (Prunus persica (L.) Batsch) used in this field experiment consisted of an early-maturing freestone cultivar, 'Flavorcrest,' grafted onto three different rootstocks: Nemagu...

Abstract The objective of this study was to determine the relationship among dry matter content (DMC) and maturity indexes at harvest quality ‘Gala’ apples after storage. Apple fruit four strains produced on two rootstocks three growing regions were used for experiments 1 2. For all experiments, assessed one day stored removal from storage plus seven days 22 °C. experiment 1, harvested weekly a...
