The performance of three different rootstock (Adara (Prunus cerasifera L.), SL 64 (Prunus mahaleb), and Colt (Prunus avium x Prunus pseudocerasus)) as nutrient suppliers has been studied for sweet cherry cultivars (Prunus avium L.). The results obtained suggested that, depending on the rootstock, the trees are submitted to different degrees of stress. According to the data obtained, it could be...

Studying the susceptibility of peach trees to Grapholita molesta (Busck) is one of the major steps in the development of pest-resistant peach varieties. This work evaluated the susceptibility of 55 genotypes of the "Prunus Rootstock Collection" ("Coleção Porta-enxerto de Prunus") of Embrapa Temperate Climate (Pelotas, Rio Grande do Sul, Brazil) to the natural infestation of G. molesta, assessed...

Prunus rootstocks play an important role in modern horticulture and commercial orchards owing to their responsibility for a wide range of characters from compatibility with cultivars to adaptation to biotic and abiotic stresses. In this study, Thirty Prunus rootstock samples were tested by 25 microsatellite markers in order to identify the genetic identity and relationships among them.17 SSR ma...

Iron deficiency induces several responses to iron shortage in plants. Metabolic changes occur to sustain the increased iron uptake capacity of Fe-deficient plants. We evaluated the metabolic changes of three Prunus rootstocks submitted to iron chlorosis and their different responses for tolerance using measurements of metabolites and enzymatic activities. The more tolerant rootstocks Adesoto (P...

doi: 10.1111/j.1399-3054.2006.00747.x Specific rootstocks can differentially influence the vegetative growth and development of fruit trees. However, the physiological mechanism involved in this phenomenon has been elusive. Recent research comparing different peach (Prunus persica L. Batsch) rootstocks suggests that the rootstock effect on vegetative growth in peach trees is associated to water...

The effect of exogenously applied auxins on oxidative stress was studied in six rootstock selections of Prunus cerasus, P. mahaleb and P. fruticosa aiming at the effect of phytohormones on the level of the lipid peroxidation (LP). Standard rootstock PHL-A was used as a control. Leaves were collected on 0, 1, 3 and 7 day of inserting cuttings into the rooting substrate. Auxin mixture consisted o...

Ten SSR loci, previously developed for Prunus, were analyzed to examine genetic relationships among 23 rootstock candidates for sweet and sour cherries, of the species P. avium, P. cerasus, P. mahaleb, and P. angustifolia. Five genotypes of P. laurocerasus, not used as rootstock, were included in the molecular analysis. The number of alleles per locus ranged from 8 to 12, with a mean of 9, whil...

We compared growth patterns and morphology of fine roots of size-controlling and invigorating peach (Prunus persica (L.) Batsch) rootstocks. Peach trees were grafted on five rootstocks: a vigorous control (Nemaguard), three intermediate vigor rootstocks (K119-50, P30-135 and Hiawatha), and a semi-dwarfing rootstock (K146-43). Minirhizotron tubes were installed at the base of trees on each roots...

mechanisms of drought stress tolerance of gf677 rootstock, peach and almond hybrid, (prunus persica × prunus amygdalus) were studied under in vitro conditions. plantlets of gf677 rootstock were subcultured into the murashige and skoog (ms) solid proliferation medium containing 1 mg/l ba (6-benzyladenine) and 0.1 mg/l naa (naphthaline acetic acid) in four drought stress levels 0 (control), 10, 2...

Čolić S., G. Zec, D. Marinković, and Z. Janković (2003): Genetic and phenotypic variability of cherry plum (Prunus cerasifera Ehrh.) pomological characteristics. – Genetika, Vol. 35, No. 3, 155-160. Cherry plum (Prunus cerasifera Ehrh.) is one of the most widely spread fruit species in our country. The fruits are mostly used for brandy production, and the seed is used for rootstock production i...
