Over the last 20 years stone fruit rootstock development has begun shifting from seedling to clonal types, many of interspecific origin. Publicly funded breeding programs have produced most of these rootstocks due to the time, cost, and risk associated with their development; however, private industry is emerging as a significant contributor of many of the newer rootstocks. Particularly notewor...

Abstract Armillaria and Desarmillaria spp. are causal agents of a devastating root-borne disease peach. Breeding resistant rootstock requires reliable screening tool. An in vitro co-culture screen designed for almond was modified by replacing agar-gelled medium with more aerated phenolic foam combining susceptible rootstocks ( i.e. , common garden experiment) minimizes variation inoculum pressu...

CBF (C-repeat Binding Factor) transcription factors are part of the AP2/ERF (Apetala2-ethylene responsive factor) domain family of DNA-binding proteins that recognize a C-repeat response cis-acting element that regulates a number of cold-responsive genes (CBF regulon). Induction of CBF gene expression by low temperature in Arabidopsis has been shown to be gated by a circadian clock. In peach (P...

An understanding of the mechanisms that determine plant response to reduced water availability is essential to improve water-use efficiency (WUE) of stone fruit crops. The physiological, biochemical and molecular drought responses of four Prunus rootstocks (GF 677, Cadaman, ROOTPAC 20 and ROOTPAC(®) R) budded with 'Catherina' peach cultivar were studied. Trees were grown in 15-l containers and ...

The article presents the results of studies to determine compatibility scion-rootstock combinations apricot and
 peach at stage growing planting material in nursery fields by using different methods. When and field, three forms incompatibility are determined exist: localized disease, starvation root system, weak cohesion between scion rootstock.
 Initially during laboratory based test...

Obtaining large and quality productions requires, in addition to agrotechnical measures, the establishment of most appropriate symbiosis between grafts (varieties) rootstocks. This variety/rootstock union particularly influences tree growth, production quality. Knowing growth root system has an important role choosing use tillage, land. The varieties nectarine on frank peach rootstock had diffe...

The Southeastern United States is facing agriculture crises, such as the ongoing epidemic of citrus greening disease that has forced region to begin looking into alternative crops. Some these belong Rosaceae genus Prunus, which encompasses many economically important species peaches, almonds, cherries, plums, and more. Peach production in Florida become a very promising citrus; however, there a...
