Influence of Scion and Rootstock on Incidence of Peach Tree Short Life
Previous work has suggested that peach scion cultivar exerts a significant influence on incidence of peach tree short life (PTSL) in trees budded onto Nemaguard and Flordaguard seedling peach rootstocks. If this influence is consistent across a range of rootstocks then the influence of scion cultivar might offer a new tool for the management of PTSL. Growers could minimize losses on those sites...
متن کاملInteractions between rootstock, inter-stem and scion xylem vessel characteristics of peach trees growing on rootstocks with contrasting size-controlling characteristics
BACKGROUND AND AIMS The primary physiological mechanism influencing tree vigour in size-controlling rootstocks of peach has been related to the hydraulic conductance of the rootstock. Differences in rootstock hydraulic conductance are a function of rootstock xylem vessel characteristics. The present research examined whether the vigour and xylem vessel characteristics of the rootstock influence...
متن کاملHydraulic conductance characteristics of peach (Prunus persica) trees on different rootstocks are related to biomass production and distribution.
We investigated hydraulic conductance characteristics and associated dry matter production and distribution of peach trees grafted on different rootstocks growing in the field. A single scion genotype was grown on a low ('K146-43'), an intermediate ('Hiawatha') and a high ('Nemaguard') vigor rootstock. 'K146-43' and 'Hiawatha' rootstocks had 27 and 52% lower mean leaf-specific hydraulic conduct...
متن کاملRelationships between xylem vessel characteristics, calculated axial hydraulic conductance and size-controlling capacity of peach rootstocks.
BACKGROUND AND AIMS Previous studies indicate that the size-controlling capacity of peach rootstocks is associated with reductions of scion water potential during mid-day that are caused by the reduced hydraulic conductance of the rootstock. Thus, shoot growth appears to be reduced by decreases in stem water potential. The aim of this study was to investigate the mechanism of reduced hydraulic ...
متن کاملGrafting Triggers Differential Responses between Scion and Rootstock
Grafting is a well-established practice to facilitate asexual propagation in horticultural and agricultural crops. It has become a method for studying molecular aspects of root-to-shoot and/or shoot-to-root signaling events. The objective of this study was to investigate differences in gene expression between the organs of the scion and rootstock of a homograft (Arabidopsis thaliana). MapMan an...
