In Citrus, flower induction represents the transition from vegetative to reproductive growth. The regulation of is mainly triggered by exposure low temperatures and water-deficit stress, which activates signaling cascade leading an increased expression citrus orthologs FLOWERING LOCUS T (CiFT). this study, relationship between rootstock under Mediterranean field conditions was investigated moni...

as regards citrus growing in sub-tropical and tropical regions that often expose drought, in order to investigation of some citrus seedlings response to drought this research was done in factorial experiment based on randomized completely design with three replication under glasshouse conditions. first factor were five citrus rootstocks and second factor included two treatment of irrigation (op...

In this study, an in vitro propagation protocol of Poncirus trifoliata L. (Raf.) rootstock, which is one the main rootstocks used citrus, was created. Monocular node parts plant, source explant, were cultured MS nutrient media containing BAP at dissmilar concentrations (0.5-1.0-2.0 mg/l). Afterward, it observed that shoot appearance and tillering achieved explants medium comprising 1.0 mg/l BAP...

in this experiment, physiological responses of two citrus rootstocks [sour orange (citrus aurantium l.) and trifoliate orange (poncirus trifoliata raf.)] were investigated under in vitro salt stress conditions. this study was conducted on a completely randomized factorial design. explants (nucellar seedling obtained from seeds) of both rootstocks were transferred to murashige and skoog (ms) sol...

Since citrus flowering is a key process in citriculture and its evaluation is often difficult due to the canopy structure and field sampling, the aim of this research was to give some directions regarding the evaluation of flowering in field-grown sweet orange plants. This study was conducted in a citrus orchard of sweet orange plants cv. ‘Valencia’ [Citrus sinensis (L.) Osbeck] grafted on ‘Cle...

Carrizo citrange (Citrus sinensisxPoncirus trifoliata) is a citrus hybrid widely used as a rootstock, whose genetic manipulation to improve different growth characteristics is of high agronomic interest. In this work, transgenic Carrizo citrange plants have been produced overexpressing sense and antisense CcGA20ox1 (a key enzyme of GA biosynthesis) under control of the 35S promoter to modify pl...

abstract one way of the increasing saline tolerance in citrus plants is grafting of sensitive commercial cultivars on to tolerant rootstocks. sweet lime (citrus limetta) is one of the most sensitive species to salinity of soil and water, and under such conditions, drastic reduction of both vegetative and yield occured. this reaserch was conducted in completely randomaized design with factorial ...

Twenty Citrus cultivars grown in the Mediterranean climate were analysed at different stages of fruit maturity to determinate changes in organic acids, vitamin C and sugars. High-performance liquid chromatographic methods were used to identify and quantify of these compounds. The influences of variety, rootstocks and different stages of fruit maturity were observed. Generally, the vitamin C con...

The Texas citrus industry in the Rio Grande Valley experiences periodic droughts. During such times, water restrictions from the Amistad and Falcon Reservoirs can reduce water available for agriculture. Irrigation in this region is primarily surface waters from the Rio Grande where citrus orchards are flood irrigated. Irrigation practices that use less water are being explored and evaluated. ...

When it comes to keeping the world green, roots have historically been considered to be mere purveyors of water and nutrients to the shoots. However, this view has changed dramatically over the past 25 years as evidence has accumulated that roots can be the ‘movers and shakers’ in orchestrating aboveground interactions between plants and their panoply of parasites (Bezemer and van Dam, 2005; Er...
