Intraspecific grafting with selected scions and rootstocks was used to study drought tolerance in the recalcitrant Mediterranean conifer P. pinaster. Conifers store different terpene types needles, stems roots, which can be modified by drought, but most studies have focused on a single organ over terpenes limits understanding of overall plant response. In this work, profile (160 components amon...

The experiment was carried out during 2015-2016, with the aim of investigating the effects of scion cultivar, rootstock age and hormonal treatments on the success of walnut minigrafting. Analysis of results showed that all studied factors were effective on graft-take and survival of minigrafted walnuts and other growth traits of the scions. The highest graft-take was observed on one-year-old ro...

The xylem-limited bacterium Xylella fastidiosa (Xf) causes Pierce's disease (PD), an important disease of grapevine, Vitis vinifera L. Grapevine rootstocks were developed to provide increased resistance to root disease, but rootstock effects on cane and vine diseases remain unclear. Grapevines that consisted of Cabernet Sauvignon or Chardonnay grafted to 13 different rootstocks were inoculated ...

Grafting is an important, widely used plant propagation technique but its physiological effects are as yet insufficiently understood. Recent studies indicate that movement of proteins and small RNAs through the graft union might be involved. MicroRNAs are known to play a significant role in regulation of higher plants’ developmental and metabolic traits. Extending this logic, we hypothesize tha...

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...

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...
