Phenolic compounds of the skin and seeds are the principal sources of wine color and structural properties. Under semi-arid conditions, irrigation management is the most determining factor of grape and wine quality while rootstocks affect numerous physiological and vegetative parameters of the scion. In the present study, compositional changes of skin and seed phenolic compounds were studied in...

The drought tolerance is a very important property of grapevine rootstocks. For that reason the breeding and selection of new rootstock varieties is focused also on the evaluation of their drought tolerance. In this experiment, altogether 20 new hybrids and 4 existing rootstock varieties were compared and evaluated. The experimental scheme involved 3 variants of water supply. Evaluated were the...

In recent years, Colomerus vitis has caused serious economic losses due to reduced grape production in Xinjiang (northwest China). Several rootstock varieties have been reported improve the resistance of Cabernet Sauvignon vitis. This study explored influence with different rootstocks on particular, Sauvignon/Cabernet (CS/CS) was selected as control, and grafted five resistant (3309C, 1103P, 14...

Introduction Fanleaf degeneration/decline disease is one of the most severe viral disease complexes of grapevine worldwide. It is also one of the oldest known viral diseases of Vitis vinifera with descriptions of symptoms being reported in Europe as early as 1841. This disease is now known to affect grapevines in all temperate regions where Vitis vinifera and hybrid rootstocks are grown. Within...

Rootstock election is one of the key decisions when designing a vineyard. Although research performed to determine effect they induce in behaviour scion varieties not scarce, it easy have global idea, as results are usually published scattered. In this work, we re-examine previous conducted Spain on rootstock implications vine agronomic performance through meta-analysis (MA). As result, were ab...

Bunch grapes ( Euvitis ) are classified as moderately salt-tolerant. However, little is known about the salt tolerance of muscadine Vitis rotundifolia ). The objective this research was to evaluate exclusion capacity relative common bunch grape rootstocks and hybrid winegrapes using a greenhouse screening assay. In two separate experiments, 31 muscadine, six rootstocks, five winegrape cultivars...

The TBP (Tubulin-Based-Polymorphism) method, based on a nuclear ILP (Intron-Length-Polymorphism) molecular marker, has been used for genotyping 37 accessions of the genus Vitis inclusive of different species, rootstocks, wild and cultivated subspecies. A distinct DNA barcode made up by a different number of amplicons, was attributed to each of the different accessions. TBP data were compared wi...

Herbivory tolerance has been linked to plant growth rate where plants with fast growth rates are hypothesized to be more tolerant of herbivory than slower-growing plants. Evidence supporting this theory has been taken primarily from observations of aboveground organs but rarely from roots. Grapevines differing in overall rates of new root production, were studied in Napa Valley, California over...

Knowledge about the growth vigor of grapevine rootstocks is required for scion-based rootstock selection and breeding. We performed this trial aiming to evaluate multiplication several rootstocks. Thirty-one genotypes were compared on their characteristics, phenological periods, indicators across three consecutive seasons. The results suggested that cuttings most had callus-forming indices (CFI...
