Previous work on citrus trees has shown that an interstock, grafted between the rootstock and scion combination, not only can improve tree growth, longevity, fruit production, and quality, but also can increase salinity tolerance. This research was designed to evaluate flooding responses of2-year-old 'Verna' lemon trees [Citrus limon (L.) Burm.; VL] either grafted on 'Sour' orange (C. aurantium...

The study of the effects of a specific stress condition on the performance of plants grown under field conditions is difficult due to interactions among multiple abiotic and biotic factors affecting the system. In vitro tissue-culture-based techniques allow the study of each adverse condition independently and also make possible to investigate the performance of genotypes of interest under stre...

BACKGROUND The future of genetic transformation as a tool for the improvement of fruit trees depends on the development of proper systems for the assessment of unintended effects in field-grown GM lines. In this study, we used eight transgenic lines of two different citrus types (sweet orange and citrange) transformed with the marker genes β-glucuronidase (uidA) and neomycin phosphotransferase ...

in this study, the effect of four citrus rootstocks {sour orange (citrus aurantium), bakraeii (c. reticulata × c. aurantium, mexican lime (c. aurantifolia) and volkamerlemon (c. volkameriana)} on orlando tangelo leaf chlorophyll content and mineral element concentrations (n, p, k, ca, na, mg, fe, zn, mn, cl, cu, and b) have been evaluated in completely randomized design with four replications. ...

Abstract Most commercial orchards of mandarins in Paraná grow ‘Ponkan’ trees predominantly grafted on ‘Rangpur’ lime. The limited genetic diversity citrus for both scion and rootstock may promote pest disease outbreaks. late season ‘Montenegrina’ willowleaf mandarin has high potential orchard diversification because its higher productivity better fruit quality. Therefore, this study assessed th...

The pathogenic effects of Pratylenchus coffeae on growth and yield of tangelo (Citrus paradisi x C. reticulata) scions grafted on rough lemon (C jambhiri), sour orange (C. aurantium) and 'Cleopatra' mandarin (C. reticulata) rootstocks were evaluated under field conditions for 4 years. Pratylenchus coffeae on inoculated trees increased to significantly damaging population densities on rough lemo...

UNLABELLED Tetraploidy modifies root anatomy which may lead to differentiated capacity to uptake and transport mineral elements. This work provides insights into physiological and molecular characters involved in boron (B) toxicity responses in diploid (2x) and tetraploid (4x) plants of Carrizo citrange (Citrus sinensis L. Osb. × Poncirus trifoliata L. Raf.), a widely used citrus rootstock. Wit...
