Introduction New rootstocks for peaches have been recently introduced into the United States through commercial nurseries. Most all of these rootstocks are complex Prunus L. hybrids that are propagated asexually. Past experience with newly introduced Prunus rootstocks has shown that extensive testing is critical to avoid potential problems in commercial situations due to nonadaptation of some r...

Grafting is the most important means of breeding peach, plum, apricot, and other fruit trees, selection rootstock crucial to quality grafting yield products. The traditional commonly used peach susceptible root-knot nematode infections, resulting in a decreased yield, while variety cherry plum rootstocks, Mirabolano 29C, resistant nematode. In this study, infection experiments on seedlin...

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...

We investigated relationships between tree water status, vegetative growth and leaf gas exchange of peach trees growing on different rootstocks under field conditions. Tree water status was manipulated by partially covering (0, approximately 30 and approximately 60%) the tree canopies on individual days and then evaluating the effects of tree water status on vegetative growth and leaf gas excha...

Criconemoides xenoplax and Meloidogyne incognita were the nematode species most frequently associated with peach in North Carolina. Other nematodes often found in high numbers on that crop were Pratylenehus vulnus, Helicotylenchus spp., Trichodorus christiei, Xiphinema amerieanum and Tylenchorhynchus claytoni. P. vulnus and P. penetrans reproduced well on rootstocks of 21 peach cultivars tested...

fruit productivity and quality of eight years peach and nectarine cultivars (rich lady, ryan sun, ruby diamond and venus) grafted onto cadaman-avimag, viking, atlas, gxn 15, gf 677, mrs 2/5 and nemaguard (control) rootstocks were evaluated. a split plot experimental design was used, with each rootstock/scion combination as an experimental unit. total yield, fruit size distribution, number of fr...

Growth, gas exchange, root hydraulic conductivity, and drought response of seedling and rooted cuttings of Lovell and Nemaguard peach [Prunus persica (L.) Batsch], and Carrizo (Poncirus trifoliata x Citrus sinensis) and sour orange (C. aurantium L.) citrus rootstocks were compared to determine the influence of propagation method on these characteristics. Rooted peach cuttings had a higher propo...

Background: Availability of quality planting materials is the major impediment in extension cultivation low chilling peach northern plans. Plum suckers are mostly used as rootstocks for raising peach; however nematode infestation a problem. Seeds all cultivars do not germinate under subtropical climate plains Northern India. Hence, an experiment was carried out at ICAR-CISH, Lucknow on seed ger...
