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...

Trials were established at Aula Dei Experimental Station (EEAD-CSIC, Zaragoza, Spain) to assess graft compatibility between peach cultivars [Prunus persica (L.) Batsch] and new Prunus spp. rootstocks or selections. Peach cvs. Catherina and Tebana and nectarine cvs. Big Top and Summergrand were grafted on peach seedlings, plum rootstocks, almond x peach hybrids, and other interspecific rootstock...

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...

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 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...

Plant interspecific periclinal chimeras are a mosaic formed by tissues from two species. They are manipulated here as an efficient plant breeding tool for cassava root yields. In this study, plants synthesized from two chimeras, designated as chimera 2 and chimera 4, were characterized morphologically and cytologically to unravel the origin of their tissue layers (L2 and L3). Root yield of the ...
