Rangpur Lime X Troyer Citrange, a Hybrid Citrus Rootstock for Closely Spaced Trees
Proc. Fla. State Hort. Soc. 99:33-35. 1986. RANGPUR LIME X TROYER CITRANGE, A HYBRID CITRUS ROOTSTOCK FOR CLOSELY SPACED TREES W. S. Castle A combination of diseases, repeated freezes, and other University of Florida, IFAS factors has reemphasized the importance of rootstocks in Citrus Research and Education Center Florida. Moreover, the effects of these factors illustrate the 700 Experiment Station Road inherent weaknesses in virtually all citrus rootstocks and Lake Alfred, FL 33850 the need to continually search for new, improved ones. Another recent trend related to rootstocks has been C. O. YOUTSEY the shift toward more closely spaced trees, particularly FDACS, Division of Plant Industry within the row (7,8). Rootstocks well-suited for dense plan Citrus Budwood Registration Bureau tings have not been available although such stocks are 3027 Lake Alfred Road being evaluated and one appears particularly promising Winter Haven, FL 33881 (1, 3, 4, 8). It is a hybrid of Rangpur lime and Troyer D. J. Hutchison citrange (RxT) and has been under study in Florida for 18 United States Department of Agriculture yr.

STANSLY−Host Suitability of Citrus and Zanthoxylum Spp. for Leuronota fagarae and Diaphorina citri (Hemiptera: Psylloidea). Florida Entomologist 97(4) (December 2014) at http://purl.fcla.edu/fcla/entomologist/browse Corresponding author: Dr. J. A. Qureshi University of Florida/IFAS Southwest Florida Research and Education Center (SWFREC) 2685 SR 29N, Immokalee, Fl 34142, USA Phone: (239) 658-3400 Fax: (239) 658-3469 E-mail: [email protected] ABSTRACT Leuronota fagarae Burckhardt (Hemiptera: Psylloidea), an exotic psyllid described from South America, was first observed in 2001on a citrus relative Zanthoxylum fagara (L.) Sarg. (Sapindales: Rutaceae) in southern Florida. Diaphorina citri Kuwayama (Hemiptera: Psylloidea) is principal vector of the bacteria ‘Candidatus Liberibacter spp.’ causal agent of huanglongbing (HLB) or citrus greening disease. Both vector and disease are now well established in Florida and also reported throughout the Americas and Asia. The host range of D. citri is limited to citrus and some rutaceous relatives. Additional vectors and host plants could accelerate spread of HLB in citrus and threaten endangered species such as Zanthoxylum coriaceum A. Rich. and Zanthoxylum flavum Vahl. Experiments were conducted to evaluate adult survival, reproduction and nymphal development of psyllids on 3 Citrus and 4 Zanthoxylum species as well as orange jasmine, Murraya paniculata (Syn. M. exotica) (Sapindales: Rutaceae), a common ornamental and preferred host of D. citri. Leuronota fagarae in single male−female pairs at 24 °C lived an average 4-47 days, 4-12 fold longer on Zanthoxylum spp. (except Z. flavum) than on citrus. -
Tetraploid Citrumelo 4475 Rootstocks Improve Diploid Common
www.nature.com/scientificreports OPEN Tetraploid Citrumelo 4475 rootstocks improve diploid common clementine tolerance to long‑term nutrient defciency Julie Oustric1*, Stéphane Herbette2, Yann Quilichini3, Raphaël Morillon4,5, Jean Giannettini1, Liliane Berti1 & Jérémie Santini1 Nutrient defciency alters growth and the production of high‑quality nutritious food. In Citrus crops, rootstock technologies have become a key tool for enhancing tolerance to abiotic stress. The use of doubled diploid rootstocks can improve adaptation to lower nutrient inputs. This study investigated leaf structure and ultrastructure and physiological and biochemical parameters of diploid common clementine scions (C) grafted on diploid (2x) and doubled diploid (4x) Carrizo citrange (C/CC2x and C/CC4x) and Citrumelo 4475 (C/CM2x and C/CM4x) rootstocks under optimal fertigation and after 7 months of nutrient defciency. Rootstock ploidy level had no impact on structure but induced changes in the number and/or size of cells and some cell components of 2x common clementine leaves under optimal nutrition. Rootstock ploidy level did not modify gas exchanges in Carrizo citrange but induced a reduction in the leaf net photosynthetic rate in Citrumelo 4475. By assessing foliar damage, changes in photosynthetic processes and malondialdehyde accumulation, we found that C/CM4x were less afected by nutrient defciency than the other scion/rootstock combinations. Their greater tolerance to nutrient defciency was probably due to the better performance of the enzyme‑based antioxidant system. Nutrient defciency had similar impacts on C/CC2x and C/CC4x. Tolerance to nutrient defciency can therefore be improved by rootstock polyploidy but remains dependent on the rootstock genotype. Fruit crops, especially citrus fruits, require large amounts of fertilizers to ensure good production and fruit qual- ity. -

C, JULY 15, 1920 No. 8 RELATIVE SUSCEPTIBILITY TO CITRUS-CANKER OF DIFFERENT SPECIES AND HYBRIDS OF THE GENUS CITRUS, INCLUDING THE WILD RELATIVES » By GEORGE I*. PELTIER, Plant Pathologist, Alabama Agricultural Experiment Station, and Agent, Bureau of Plant Industry, United States Department of Agriculture, and WILLIAM J. FREDERICH, Assistant Pathologist, Bureau of Plant Industry, United States Department of Agriculture 2 INTRODUCTION In a preliminary report (6)3 the senior author briefly described the results obtained under greenhouse conditions for a period of six months on the susceptibility and resistance to citrus-canker of a number of plants including some of the wild relatives, Citrus fruits, and hybrids of the genus Citrus. Since that time the plants reported on have been under close observation; a third experiment has been started, and many inoculations have been made in the isolation field in southern Alabama during the summers of 1917, 1918, and 1919. Many more plants have been successfully inoculated; others have proved to be extremely sus- ceptible; while some of those tested still show considerable resistance. The results obtained up to November 1, 1919, are described in tjhis report. EXPERIMENTAL METHODS In the greenhouse, the methods used and the conditions governing the inoculations described in the preliminary report were closely fol- lowed. The same strain of the organism was used and was applied in the 1 Published with the approval of the Director of the Alabama Agricultural Experiment Station. The paper is based upon cooperative investigations between the Office of Crop Physiology and Breeding Investi- gations, Bureau of Plant Industry, United States Department of Agriculture, and the Department of Plant Pathology, Alabama Agricultural Experiment Station. -
The Satsuma Mandarin1 Peter C
HS195 The Satsuma Mandarin1 Peter C. Andersen and James J. Ferguson2 Scientific Name Family Citrus unshiu Marcovitch Rutaceae Common Name Origin In most citrus producing areas, satsuma mandarin is the China and Japan preferred name, but satsuma tangerine is also used (Figures 1 and 2). Distribution Satsumas are grown in cool subtropical regions of Japan, Spain, central China, Korea, Turkey, along the Black Sea in Russia, southern South Africa, South America, and on a small scale in central California and northern Florida. The world’s largest satsuma industry is located in southern Ja- pan where climatic conditions are favorable for the produc- tion of early ripening satsuma mandarins of high quality. Selection of slight mutations and seedlings from controlled pollinations over many years has resulted in a collection of Figure 1. A satsuma orchard in north Florida. over 100 cultivars that differ in date of maturity, fruit shape, Credits: P. C. Andersen color, and quality. ‘Owari’ is the primary satsuma cultivar commercially grown in Florida, but ‘Brown Select’, ‘Early St. Ann’, ‘Silverhill’, and ‘Kimbrough’ are also available. History Satsuma mandarin may have originated in China, but it was first reported in Japan more than 700 years ago, where it is now the major citrus species grown. The first recorded introduction into the United States was in Florida by George R. Hall in 1876. The name “satsuma” is credited to Figure 2.
