‘Honeycrisp’ apple is susceptible to bitter pit, which associated with fruit mineral nutrient composition. Rootstock genotypes can affect acquisition, distribution, and yields, all composition pit susceptibility. However, the changes of these traits among different rootstock in response abiotic stress under semiarid conditions are relatively unknown. The objective this study was evaluate influe...

Local translocation of small RNAs between cells is proved. Long distance translocation between rootstock and scion is also well documented in the homo-grafting system, but the process in distant-grafting is widely unexplored where rootstock and scion belonging to different genera. Micro RNAs are a class of small, endogenous, noncoding, gene silencing RNAs that regulate target genes of a wide ra...

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...

Background and Aims The use of rootstocks to enhance the performance low-yielding wine cultivars grown under hot irrigated conditions was studied. Methods Results Field grape composition low-vigour (Chasselas, Egiodola, Ehrenfelser, Gamay, Perdea, Reichensteiner Roussanne) as own roots or grafted on (1103 Paulsen, Dog Ridge, Ramsey, Schwarzmann SO4) were assessed over three seasons. Across all ...

Nemaguard has been the workhorse rootstock of the California almond industry for many decades. It is well adapted to the well-drained, non-calcareous loam and sandy loam soils common throughout the San Joaquin Valley. Nemaguard is vigorous, immune to rootknot nematode, compatible with all almond varieties, doesn’t sucker much, has decent anchorage and is easy to grow at the nursery. However, th...
