Turkish Journal of Agriculture and Forestry
Mandarin (Citrus reticulate Blanco) and lemon (C.limon L.) are among the most cultivated Citrus species in the world. Among different approaches, gamma radiation is widely used to induce mutations in citrus breeding studies. Gamma radiation causes DNA damage, randomly inducing several mutations in the genome. Molecular techniquesarewidely used to detect such induced mutations and genetic diversity in plants.In this study, simple sequence repeats (SSR), inter-simple sequence repeat (ISSR) and single-strand conformation polymorphism (SSCP) markers were used to detectthe induced mutations andgenetic diversityin someirradiated mandarin and lemon genotypes in comparison with standard citrus varieties. The irradiated genotypes used in this study …
Efficient Protoplast Isolation From Ovule-Derived Embryogenic Callus In Citrus Volkameriana, Berken Çi̇men

Turkish Journal of Agriculture and Forestry
The present study reports on the isolation of viable protoplast from ovule-derived embryogenic calli of Volkameriana (Citrus volkameriana L.), which is a rootstock in high demand for lemon production.Ovules of C. Volkameriana isolated at 3 different immature fruit stages, comprising4, 8, and 12 weeks after anthesis (WAA), were cultured on5 different media in order to produce embryogenic callus lines as a source material for protoplast isolation. EME medium (MT basal medium + 0.5 gL-1 malt extract), with the addition of phytohormones [kinetin (KIN), 2,4-dichlorophenoxyacetic acid (2,4-D) and 6-benzylaminopurine (BAP)] at different concentrations, were tested for callogenesis.

Comparison Of Fixed-Wing Unmanned Aircraft Systems (Uas) For Agriculture Monitoring, Joseph Cerreta, Kristine M. Kiernan
Comparison Of Fixed-Wing Unmanned Aircraft Systems (Uas) For Agriculture Monitoring, Joseph Cerreta, Kristine M. Kiernan
International Journal of Aviation, Aeronautics, and Aerospace
Florida citrus growers need inexpensive methods to observe citrus plants to detect disease and stress consistently. Health vegetation indices, such as the Normalized Difference Vegetation Index (NDVI) collected from Unmanned Aircraft Systems (UAS), can be used to identify variation in plant health. Simple-to-operate UAS may enable growers to determine within-field variation more frequently than with inspections from scouts, providing more frequent knowledge about the crop condition. This research compared two low-cost fixed-wing UAS, a $5,000 Parrot Disco Pro Ag and a $16,690 senseFly eBee, each equipped with a Parrot Sequoia multispectral camera, to determine if there were differences in the …
Using 3 Dimension Health Vegetation Index Point Clouds To Determine Hlb Infected Citrus Trees, Joseph Cerreta, Ashley Hanson, Julianna E. Martorella, Stacy Martorella
Using 3 Dimension Health Vegetation Index Point Clouds To Determine Hlb Infected Citrus Trees, Joseph Cerreta, Ashley Hanson, Julianna E. Martorella, Stacy Martorella
Journal of Aviation/Aerospace Education & Research
Three-dimensional NDVI point clouds can be an innovative method for detecting Huanglongbing (HLB) disease in citrus trees. In February 2018, an Unmanned Aircraft System (UAS) captured narrow-band multispectral images to detect healthiness variations of infected citrus trees. A 30-acre section of a citrus grove in Florida with a known HLB infection was examined to determine if three-dimensional Normalized Difference Vegetation Index (NDVI) point clouds can indicate healthiness variations in HLB-infected citrus trees and how three-dimensional NDVI point clouds compared to two-dimensional NDVI reflectance maps for detecting healthiness variations in HLB-infected citrus trees. Wilcoxon Sign Rank testing compared Whole-Tree Vegetation Indices …

Turkish Journal of Agriculture and Forestry
This study aimed to determine the antioxidant capacity; the total phenolic, total carotenoid, sugar, and ascorbic acid contents; and some pomological characteristics of Citrus species (Citrus reticulata, Citrus sinensis, and Citrus paradisi) and mandarin (Citrus reticulata) and their new hybrids developed for yield at the Alata Horticultural Research Institute in Mersin, Turkey. With respect to antioxidant capacities, the highest value (45.28 µmol TE/100 g) was determined in Cocktail (Citrus paradisi) cultivar fruits among all examined cultivars and hybrids. We found that 7-19 (Clementine x Kara) mandarin hybrids had the highest total phenolic content (386.81 mg gallic acid equivalent/g) and the …
Effect Of Exogenously Applied Spermidine On Growth And Physiology Of Citrus Rootstock Troyer Citrange Under Saline Conditions, Muhammad Akbar Anjum
Effect Of Exogenously Applied Spermidine On Growth And Physiology Of Citrus Rootstock Troyer Citrange Under Saline Conditions, Muhammad Akbar Anjum
Turkish Journal of Agriculture and Forestry
The aim of this study was to assess the effects of spermidine (Spd) on ameliorating adverse effects of salinity in Troyer citrange seedlings. For this purpose, 6-month-old, uniform-sized seedlings of Troyer citrange were transplanted to plastic containers containing Hoagland nutrient solution. Addition of 75 mM NaCl into the nutrient solution reduced the plant growth, leaf chlorophyll content, chlorophyll fluorescence yield (Fv/Fm), net photosynthetic rate, respiration rate, and total Spd, N, and Ca^{2+} + Mg^{2+} contents of the leaves. It increased the leaf proline, total putrescine (Put), total spermine (Spm), Na^+, and Cl^- contents of the leaves. Addition of Spd (0.1 …
Molecular Characterization And Genetic Diversity Analysis Of Citrus Cultivars By Rapd Markers, M. N. R. Baig, Sapna Grewal, Santosh Dhillon
Molecular Characterization And Genetic Diversity Analysis Of Citrus Cultivars By Rapd Markers, M. N. R. Baig, Sapna Grewal, Santosh Dhillon
Turkish Journal of Agriculture and Forestry
Random Amplified Polymorphic DNA (RAPD) markers were used to evaluate genetic similarity and inter-relationship among 18 citrus cultivars, including 13 species and 5 hybrids. Out of 40 decamer primers screened, 25 were selected which produced 250 markers; of which 231 were polymorphic and some species or cultivar specific RAPD markers. The Jaccard coefficient was used to calculate the genetic similarity. UPGMA was used to generate the dendrogram which clearly separated Jatti-Khatti from all major clusters at a similarity coefficient of 0.61. The average genetic similarity value observed across all the genotypes was 0.63, with the 2 sweet orange cultivars, Jaffa …
Mandarin Yield Response To Partial Root Drying And Conventional Deficit Irrigation, Cevat Kirda, Fati̇h Topaloğlu, Sevi̇lay Topçu, Harun Kaman
Mandarin Yield Response To Partial Root Drying And Conventional Deficit Irrigation, Cevat Kirda, Fati̇h Topaloğlu, Sevi̇lay Topçu, Harun Kaman
Turkish Journal of Agriculture and Forestry
Fruit yield response of a mandarin (Citrus reticulata cv. Marisol) orchard to deficit irrigation, which was imposed either through conventional deficit irrigation (DI) or a newly evolving irrigation technique, called partial root drying (PRD), was investigated. The PRD practice simply requires wetting of one half of the rooting zone and leaving the other half dry, thereby utilising reduced amount of irrigation water applied. The wetted and dry sides are interchanged in the subsequent irrigations. Six irrigation treatments were tested: (1) TR, traditional farmers’ method of irrigation where irrigation management was left to the full control of a grower; (2) FULL …

Determination Of The Effect Of Fosetyl-Al Against Citrus Gummosis Disease Caused By Phytophthora Citrophthora(Smith And Smith) Leonian, Ali̇ Erkiliç, Yeter Canihoş
Turkish Journal of Agriculture and Forestry
In this study the effect of fosetyl-Al against citrus root not and gummosis caused by Phytophthora citrophthora was investigated. The results showed that fosetyl-Al protected citrus from the disease at least for one year. It was found that two fungicide applications sufficiently protected the trees against citrus gummosis. No significant differences were obtained were obtained at two fungiciede dosages, 160 g a.i./100L and 200 g a.i./100L, in all applications. When the pathogen was inoculated two weeks before fosetyl-Al, the infection area was diminished and with time had complete recovery with callus formation. Thus, fosetyl-Al was shown to have a curative …
