... Citrus tristeza virus in Australian citrus is a complex of isolates that differ in biological properties and rates of aphid transmission. Biological characterization of isolates on citrus indicators produced a range of symptoms varying in type and severity depending on the field host and geographical location. Single aphid transmissions with the vector Toxoptera citricida separated some of these s ...
... The Diagnosis and Recommendation Integrated System (DRIS) has been found reliable in diagnosing nutrient requirements, despite changes in the tissue sampling or the time sampling. Relatively few researchers use the results obtained by hydroponic culture to make a DRIS data bank. In this work, results obtained in this way have been utilized as DRIS reference values to evaluate the iron (Fe) supply ...
... Somatic hybridization experiments in Citrus that involve the fusion of protoplasts of one parent isolated from either nucellus-derived embryogenic callus or suspension cultures with leaf-derived protoplasts of a second parent, often result in the regeneration of diploid plants that phenotypically resemble the leaf parent. In this study, plants of this type regenerated following somatic fusions of ...

Cuban citriculture has recently been affected by important pests and diseases including black citrus aphid Toxoptera citricida Kirkaldy, citrus leafminer Phyllocnistis citrella Stainton, Asiatic citrus psyllid Diaphorina citri Kuwayama, Citrus tristeza disease, and huanglongbing. This complex of ‘invasive species’ is thought to be contributing to the increasing decline of commercial citrus groves. ...
... Isolate TEB1 an antagonistic endophytic bacterium, obtained from citrus leaves and identified as Bacillus amyloliquefaciens by 16S rDNA sequencing, was used for the biological control of mal secco disease of Citrus aurantium seedlings caused by the mitosporic fungus Phoma tracheiphila. The isolate TEB1 exhibited a good in vitro activity against P. tracheiphila in dual cultures as well as with the ...
... Citrus limonoids were demonstrated to possess potential biological activities in reducing the risk of certain diseases. Limonoids are present in citrus fruits in the form of aglycones and glucosides. At present, limonoid aglycones and limonoid glucosides are extracted in multiple steps using different solvents. In order to understand their potential bioactivity, it may be beneficial to isolate and ...
... Bergamot (Citrus aurantium L. subsp. bergamia) essential oil (BEO) is used in folk medicine as an antiseptic and anthelminthic and to facilitate wound healing. Evidence indicates that BEO has substantial antimicrobial activity; however its effects on immunity have never been examined. We studied the effects of BEO on reactive oxygen species (ROS) production in human polymorphonuclear leukocytes (P ...
... Ascorbic acid (AsA) and melatonin (Mel) are known molecules participating in stress resistance, however, their combined role in counteracting the impact of salinity in plants is still unknown. In this work the effect of exogenous application of 0.50 mΜ AsA, 1 μΜ Mel and their combination (AsA + Mel) on various stress responses in leaves and roots of Citrus aurantium L. seedlings grown under 100 mΜ ...
Citrus aurantium; Citrus macrophylla; color; drought; fruiting; fruits; growers; growing season; irrigation management; irrigation water; leaf water potential; leaves; lemons; mulching; orchards; rootstocks; solar radiation; temperature; trees; water salinity; Spain
Abstract:
... The external color of lemons is one of the most important attributes for the consumer. It is known that the natural process of de-greening mainly depends on the temperature, although other agronomic factors could also affect this process. Currently, citrus orchards in Eastern Spain suffer drought and salinity problems, and growers use a series of agronomic strategies − such as the use of tolerant ...
... Background and Aims The origin of limes and lemons has been a source of conflicting taxonomic opinions. Biochemical studies, numerical taxonomy and recent molecular studies suggested that cultivated Citrus species result from interspecific hybridization between four basic taxa (C. reticulata, C. maxima, C. medica and C. micrantha). However, the origin of most lemons and limes remains controversial ...
... Citrus plants belonging to the family Rutaceae which include fruits such as orange, mandarin, lime, lemon, sour orange and grapefruitappear as a well known promising source of multiple beneficial nutrients for human beings. Processing of citrus by-products potentially represents a rich source of phenolic compounds and dietary fibre, owing to the large amount of peel produced. These citrus fruit re ...
Citrus aurantium; Citrus limonia; fresh market; fruit peels; leaves; malondialdehyde; market value; oils; oranges; reactive oxygen species; rootstocks; scions; summer; transpiration; trees; water content; water potential
Abstract:
... Citrus fruit is prone to on-tree oleocellosis (OTO), which decreases its fresh market value due to deterioration in the fruit peel. This study aimed to evaluate the effects of Lichi16-6 trifoliata (Poncircus trifoliate, LC), Goutoucheng sour orange (Citrus aurantium, GT), and Rangpur lime (C. limonia Osbeck, RL) rootstocks on the occurrence of OTO, plant water status, reactive oxygen species (ROS) ...
... This study was conducted in order to examine the effect of different rootstocks on vegetative growth and mineral elements' content in scion of different Persian lime genotypes. For this purpose, this study was arranged as factorial in randomized complete block design with two factors including rootstock (Bakraei, Mexican lime, Volkamer lemon and Sour orange) and scion (IAC, Tahiti lime, Deperse li ...
... Citrus fruits have been introduced to the Mediterranean area from Asia for centuries and spontaneous crosses have generated several hybrid forms, some of which have had agricultural or industrial success while others have remained niche food or ornamental products, or have disappeared. Pompia (C. medica tuberosa Risso & Poiteau) is an old endemic citrus fruit from Sardinia of unknown genetic origi ...
... Essential oil (EO) of Citrus has some biological and pharmaceutical properties; thus, it can be used in food and drug industries. Changes in growing seasons play important roles in physiological processes of Citrus EO especially that extracted from young leaves. The aim of this study was to evaluate the EO extracted from young leaves of twelve Citrus species in different seasons (winter, spring, s ...
Citrus aurantium; Parlatoria ziziphi; females; instars; lemons; males; pest control; pests; quarantine; research; species identification
Abstract:
... Pest control is easier and more effective when pests are correctly identified. The Black Parlatoria Scale, Parlatoria ziziphi (Lucas, 1853) (Hemiptera: Coccomorpha: Diaspididae) is an important invasive pest in citrus-growing countries. This diaspidid has historically been difficult to control, because its immature stages are difficult to identify due to confusion with similar Parlatoria species. ...
... Dodder is a parasitic weed that causes a lot of damage to citrus production in the south of Kerman province, Iran. Introducing cultivars which tolerant to this parasite can be considered a very effective step in controlling it. Therefore, to evaluate the tolerance of seven important citrus species to dodder, an experiment was conducted in a randomized complete block design with three replicates in ...
