Apple scions with diverse growth habits were grafted on various size-controlling rootstocks and morphological characteristics were measured after 6 years of growth in the field. Scion had more influence than rootstock on monthly growth rate. Across all rootstocks, scions with spreading growth habits grew rapidly in April and May and achieved most seasonal growth earlier than scions with upright...

Root-knot nematode-susceptible melons (Cantaloupe) were grown in pots with varying levels of Meloidogyne incognita and were compared to susceptible melons that were grafted onto Cucumis metuliferus or Cucurbita moschata rootstocks. In addition, the effect of using melons as transplants in nematode-infested soil was compared to direct seeding of melons in nematode-infested soil. There were no di...

Studies have shown the importance of oxygenated compounds in beverage and food products. Citrus rootstocks seem to have a profound influence on oxygenated compounds in plants. The goal of the present study was to investigate the effect of rootstocks on the oxygenated compounds in Citrus clementina.  Flower oil components were extracted using an ultrasonic bath and eluted with n-pentane: diethyl...

The response of the peach scion cultivars, Jerseyqueen, Redhaven, Compact Redhaven, and Rio Oso Gem and rootstocks 'Lovely and 'Nemaguard' to inoculation with Meloidogyne incognita was compared in vitro and in microplots. One or more parameters monitored in vitro correlated with at least one parameter monitored in microplots, 4 years after tree planting (1989). A range of responses was observed...

The remobilization of storage nitrogen (N) is affected by growth characteristics young pear trees. Aboveground parts trees grafted on P. betulifolia grew more vigorously than that dwarfing rootstocks. Therefore, the N within vigorous rootstocks may be different from A 15N tracing experiment, including six groups one-year-old in 2016, was conducted to investigate mobilization 2016 2018. Results ...

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...

Rootstocks are among the main factors that influence grape development as well as fruit and wine composition. In this work, rootstock/scion interactions were studied using transcriptomic and metabolic approaches on leaves of the "Gaglioppo" variety, grafted onto 13 different rootstocks growing in the same vineyard. The whole leaf transcriptome of "Gaglioppo" grafted onto five selected rootstock...

To understand the adaptation of grape rootstocks commonly used in major grape production areas worldwide to Florida, where Pierce’s dsease (PD) is the primary limiting factor in grape production, ten important grape rootstocks were cultivated at the experimental vineyard, Florida A&M University, Tallahassee, Florida. Disease resistance and symptoms and growing performance were evaluated. PD sym...

genetic diversity of 36 genotypes of dwarf and semi-dwarf apple rootstocks along with seven iranian dwarf rootstocks were investigated by use of rapd dna markers. a set of 100 random primers was utilized in pcr reaction from which 10 primers resulted in good amplification with high polymorphism. among primers, 10 selected rapd primers produced 160 bands, in which, 136 were polymorphic. cluster ...

a greenhouse experiment was performed in the framework of a completely randomized design and a factorial arrangement to evaluate the effect of arbuscular mycorrhizal fungi (amf) on growth and on root antioxidant enzyme changes of two citrus rootstocks (sour orange and rough lemon). the experimental factors were: mycorrhizal treatments at two levels (inoculation with glomus mosseae vs. control) ...
