ROLE OF THE ROOTSTOCK IN INFLUENCING FRUIT QUALITY AND TOLERANCE TO SALT STRESS IN PIGMENTED CITRUS SPECIES
L’agricoltura è uno dei principali settori dell'economia del Mediterraneo e italiana e gli agrumi sono la prima coltura frutticola in termini di produzione mondiale con 157 milioni di tonnellate. Il portinnesto ha svolto per centinaia di anni un ruolo determinante sulla produzione, sulla qualità …

Root restriction, under-trellis cover cropping, and rootstock modify vine size and berry composition of Cabernet Sauvignon
… manipulation, under-trellis ground cover, and rootstock. Treatment levels were root bag (RBG) or no root manipulation (NRM); under-trellis cover crop (CC) or herbicide strip (HERB); and one of three rootstocks: 101-14, Riparia Gloire, or 420-A. Effects of these treatments were measured in two …

Systems-Level Analysis of Rootstock–Scion Interactions in Apple Reveals Mechanisms of Cold Tolerance Under Field Frost Events
… floral buds, yet the mechanisms underlying rootstock-dependent cold tolerance in orchard conditions remain poorly understood. In this study, we investigated frost tolerance in two apple (Malus domestica Borkh.) cultivars, 'Fuji' and 'Gala', grafted onto ten different rootstocks over the …

Groundcover, rootstock and root restriction effects on vegetative growth, crop yield components, and fruit composition of Cabernet Sauvignon
… optimum quality wine production. Cover crops, rootstocks and rootzone restriction were evaluated for their effect on vegetative and reproductive growth on Cabernet Sauvignon. Treatments were arranged in a strip-split-split plot arrangement with under-trellis cover crops (UTCC) compared to …

The Effects of Rootstock Selection and Carbon-based Fertility Amendments on Apple Orchard Productivity and Soil Community Ecology
In apple (Malus domestica Borkh.) orchards, rootstock genotype, and soil fertility management practices impact soil fertility, plant associated soil microbial communities, and orchard productivity. Apple growers select rootstocks to confer beneficial traits, including size control, precocity, and …

Identification of clone x rootstock effects on cold hardiness and relevant dehydrins changes in Cabernet franc (Vitis vinifera L.)
… has been given to the effect of clone and rootstock. This study investigates the bud cold hardiness of Cabernet franc with different clones and rootstock combinations throughout dormancy during the stages of cold acclimation, maximum hardiness and deacclimation. The research also looks at …

Evaluation of rootstock and crop load effects on the performance of `Gibson Golden Delicious' and three scab-resistant apple cultivars
… challenges such as selection of good quality rootstocks and crop load management for high quality fruit and consistent apple production across growing seasons. The primary objective of this investigation was to evaluate the effect of rootstocks and cropping densities on fruit quality …

INFLUENCE OF THE INTERACTION SCION X ROOTSTOCK ON GRAPEVINE RESPONSE TO DROUGHT STRESS AS A TOOL IN NEW GRAPEVINE ROOTSTOCKS BREEDING PROGRAMS.
… conditions, and the use of drought-tolerant rootstocks is considered an effective mid-term solution to mitigate and manage these negative impacts. However, the range of available rootstocks is limited, and most of them were selected in the late 19th century, when grapevine cultivation …

The genetic determinants of vigour control and precocity by pear (Pyrus communis L.) rootstocks
… traits in commercial pear production. Dwarfing rootstocks are used to reduce the size of the scion and enable precocious flowering in many perennial cultivars. Currently there is a lack of Pyrus rootstocks that are vigour-controlling and precocity-inducing. The development of such a rootstock is …

Molecular Characterization of Citrus Tristeza Virus Isolates in Commercial Citrus Grown in Belize
… and slow decline on sweet and sour orange rootstock combination on field trees. One isolate on Cleopatra mandarin rootstock expressed no field symptoms but may be a possible source of a detrimental isolate to more susceptible citrus rootstock combinations. Field plants and field source …

Investigation of Yield and Quality of Grafted Heirloom and Hybrid Tomatoes
… the uniting of a shoot or bud scion with a rootstock to form a compound plant, mainly for managing soil-borne diseases and increasing crop yield. The objectives were to examine the effects of reciprocal and self grafts on tomato fruits, number of fruits, weight, and quality of the cultivars, …

Storage and mobilization of nitrogen in the peach tree / by B.K. Taylor.
… in young peach trees (Golden queen on Elberta rootstock), and the importance of this stored nitrogen for new growth, were investigated in this thesis. In addition, the metabolic stability of constituents of the storage nitrogen of dormant peach trees was studied.

PHENOTYPING OF GRAPEVINE ROOT SYSTEM FOR DROUGHT ADAPTATION
… strategies, the adoption of drought tolerant rootstocks has emerged as one of the most promising and sustainable approaches. Since the outbreak of Phylloxera in the 19th century grapevine has been predominantly propagated through grafting and rootstocks have become essential tools to regulate …

Phaeomoniella chlamydospora: potential inoculum sources in the grapevine propagation process
… isolated from 65% of positive samples. Infected rootstock mother-vines were a source of inoculum as young own-rooted rootstock and grafted vines had infection levels of 42% and 18%, respectively, 8 months after planting. Infection increased over time but was absent in own-rooted scion until 20 …

Identification and expression analysis of putative NLR genes in avocado, Persea americana, during infection by the oomycete, Phytophthora cinnamomi
… This pathogen causes root necrosis in infected rootstocks, which may ultimately lead to plant death and thus economic losses. The complex molecular interactions between avocado and P. cinnamomi are not well understood and might be the key to breeding P. cinnamomi resistant rootstocks. …

Laboratory evaluation of some Malus cultivars and hybrids to attack by pine voles
… resistance of one-year-old stems of 111 Malus rootstock cultivars and hybrids to pine vole damage. The tank fest proved to be an excellent method for: testing several clones at one time; providing the animals with more of a natural environment; exposing all animals to each stem in the test; and …
