It is well known that rootstocks can have an effect on the vegetative growth and development of the tree; however, there has been no clear explanation about the physiological mechanism involved in this phenomenon. Evidence indicates that the rootstock effects on tree vegetative growth may be related to hydraulic limitations of the rootstock. The objective of these experiments was to investigate...

The vegetative performance of four nectarine tree scion/rootstock combinations, with varying growth capacities, were analysed in the Spring after the canopy:root ratio was dramatically reduced by severe pruning in the dormant season. We anticipated that severe pruning and reduction of the shoot:root ratio would mitigate known root water supply limitations related to the various rootstocks and d...

Two independent trials were established during the years of 2009 and 2010 with M.26 apple rootstocks and Prunus mahaleb L. seedlings in three different locations to evaluate the effect of seven organic fertilizers and amendments on the growth of rootstocks in an organic nursery in the first year of an operation. The products tested were a microbial consortium, two kinds of vermicomposts extract...

Two apple rootstock genotypes G.935 and B.9 were recently demonstrated to exhibit distinct resistance responses following infection by Pythium ultimum. As part of an effort to elucidate the genetic regulation of apple root resistance to soilborne pathogens, preinoculation transcriptome variations in roots of these two apple rootstock genotypes are hypothesized to contribute to the observed dise...

Apple canker caused by the phytopathogenic fungus Neonectria ditissima is an economically important disease, which has spread in recent years to almost all pome-producing regions of the world. N. ditissima is able to cross-infect a wide range of apple varieties and causes branch and trunk lesions, known as cankers. Most modern apple varieties are susceptible and in extreme cases suffer from hig...

Background: The results of studies the influence long-term fertilization on parameters growth apple trees Aidared variety seed and vegetative M.4 rootstocks during repeated cultivation dark gray podzolic soil were considered. Methods: research was conducted 1990-2016 in tree plantation Uman National University Horticulture an experiment with use different systems. Result: It found that length s...

This article presents the results of a study effect treatment root system M9 stock with microbiological preparation Agrinos 1, which is consortium natural soil microorganisms - more than 80 strains from 10 families in combination 2, containing complex bioavailable nutrients (macro-, microelements, protein, amino acids, chitin, chitosan) order to activate metabolic processes, reduce impact stres...

Orchard intensification is motivated by the desire to produce fruit early in the life of the orchard to rapidly recover establishment costs. Intensification is possible using dwarfing rootstocks that control tree size, induce early cropping and produce large quantities of fruit compared to the amount of wood produced. Therefore, this study attempts to compare some yield and fruit properties of ...
