Reaction of Tangerines Genotypes to Elsinoe Fawcettiiunder
Reaction of tangerines genotypes to Elsinoe fawcettii under natural infection conditions Crop Breeding and Applied Biotechnology 11: 77-81, 2011 Brazilian Society of Plant Breeding. Printed in Brazil Reaction of tangerines genotypes to Elsinoe fawcettii under natural infection conditions Marcelo Claro de Souza1*, Eduardo Sanches Stuchi2 and Antonio de Goes3 Received 11 February 2010 Accepted 30 September 2010 ABSTRACT - A citrus scab disease, caused by Elsinoe fawcettii, is currently found in all citrus areas throughout Brazil. That being, given the importance of this casual agent, the behavior of tangerines and hybrids influenced by this pathogen was evaluated under natural infection conditions. This study was performed with plants around 15 years old without irrigation; 100 fruits of three plants were collected during harvest season, using a grade scale varying from 0 (absence of symptoms) to 6 (severe symptoms) the level of disease severity was determined. Among the cultivars, citrus scab resistance was observed in Citrus deliciosa, C. tangerina, C. nobilis; a mandarin hybrid (C. nobilis x C. deliciosa) and a satsuma hybrid (C. unshiu x C. sinensis). Among the other genotypes, symptoms were observed with levels of severity ranging from 1 to 3, indicating moderate resistance. Key words: Citrus scab, citrus crop, resistant varieties.

Tropical Horticulture: Lecture 32 1
Tropical Horticulture: Lecture 32 Lecture 32 Citrus Citrus: Citrus spp., Rutaceae Citrus are subtropical, evergreen plants originating in southeast Asia and the Malay archipelago but the precise origins are obscure. There are about 1600 species in the subfamily Aurantioideae. The tribe Citreae has 13 genera, most of which are graft and cross compatible with the genus Citrus. There are some tropical species (pomelo). All Citrus combined are the most important fruit crop next to grape. 1 Tropical Horticulture: Lecture 32 The common features are a superior ovary on a raised disc, transparent (pellucid) dots on leaves, and the presence of aromatic oils in leaves and fruits. Citrus has increased in importance in the United States with the development of frozen concentrate which is much superior to canned citrus juice. Per-capita consumption in the US is extremely high. Citrus mitis (calamondin), a miniature orange, is widely grown as an ornamental house pot plant. History Citrus is first mentioned in Chinese literature in 2200 BCE. First citrus in Europe seems to have been the citron, a fruit which has religious significance in Jewish festivals. Mentioned in 310 BCE by Theophrastus. Lemons and limes and sour orange may have been mutations of the citron. The Romans grew sour orange and lemons in 50–100 CE; the first mention of sweet orange in Europe was made in 1400. Columbus brought citrus on his second voyage in 1493 and the first plantation started in Haiti. In 1565 the first citrus was brought to the US in Saint Augustine. 2 Tropical Horticulture: Lecture 32 Taxonomy Citrus classification based on morphology of mature fruit (e.g. -
Queensland Brain Institute 2017 Annual Report Director’S Message
Queensland Brain Institute 2017 Annual Report Director’s message 2017 was another year of strong achievement in our research output, as reflected in the number and quality of our peer-reviewed publications in leading scientific journals, and our grant success in both the NHMRC Project Grant and the ARC Discovery Project schemes. It was particularly pleasing that many of our younger recruits obtained grant funding. QBI’s clinical links were strengthened through a joint appointment with Mater Neuroscience; Professor Peter Nestor, a clinical neurologist from the German Center for Neurodegenerative Diseases, started in October. Refurbishment of the Ritchie building occurred during much of the year, and a number of Faculty have moved across into the new space; the breakthrough from the Clem Jones Centre for Ageing Dementia Research (CJCADR) into the Ritchie building on Level 3 is also complete, and seamlessly links the two buildings. This space forms a visible clinical interface for QBI, and will include a Memory Clinic for testing patients with neurodegenerative diseases. In August, QBI hosted the first official visit of the newly appointed International Research Review Board. Half of the Faculty were reviewed, and the research focus, current and future, of the Institute was reviewed. The remaining half are also scheduled for review in December 2018. The initial Report was very supportive, and noted that the breadth of neuroscience research was impressive, and that QBI is a world-leading Institute that enjoys high international visibility. Recommendations outlined in the Report will be examined in detail over the coming year. Professor Pankaj Sah Director, Queensland Brain Institute Queensland Brain Institute Annual Report 2017 1 Research highlights There were several major research discoveries in 2017, as well as the progression of a number of research outcomes towards commercialisation. -

Tangerines, Mandarins, Satsumas, and Tangelos
Tangerines, Mandarins, Satsumas, and Tangelos Category: Semi-evergreen Hardiness: Damage will occur when temperatures drop below the low 20’s Fruit Family: Citrus Light: Full sun to half day sun Size: 10’H x 10’W; may be pruned to desired HxW Soil: Well-drained Planting: Plant after danger of frost has passed, mid to late March The name “tangerine” derives from one variety that was imported to Europe from Tangiers. There are many named varieties of what citrus growers call “mandarins” because of their Asian origins. One of these, the “Satsuma”, is an heirloom Japanese mandarin that is both delicious and especially adapted to Southeast Texas. It has been part of Gulf Coast Citrus history for a century. There are many named varieties of Satsumas. Mandarins are mostly orange-fleshed, juicy, highly productive, very easy to care for, long-lived, easily peeled and segmented or juiced. Few fruits can match the mandarin. Satsumas are seedless or close to seedless. They are all of outstanding quality and differ little among themselves except for when they ripen. Buy early, mid and late season varieties to have months of ripe fruit harvests from September to April. Care of Mandarins and related fruits Planting: Newly purchased citrus have probably not been hardened off to tolerate our winter weather. Keep your citrus in the container until late March, or until all danger of freeze has passed. Trees can be kept outside in a sunny area on mild days and nights, but move them into the shelter of the garage or house if frost is predicted. -
Rangpur Lime Disease and Its Relatiomship to Exocortis
RANGPUR LIME DISEASE AND ITS RELATIOMSHIP TO EXOCORTIS Instituto Agronomico, Campinas, Sgo Paulo, Brazil INTRODUCTION The Rangpur lime has been used in Brazil more or less extensively as a rootstock for several orange varieties since the early citrus plantings were established. When the tristeza disease invaded and destroyed those Brazilian citrus groves which were budded on sour orange- and sweet lime (lima da Persia), it was demonstrated (5)*, that the Rangpur lime was tolerant to tristeza virus. Since then, nurserymen and growers have favored its use as rootstock for many kinds of citrus plants. However, the young plant- ing~soon showed symptoms of a "new disease" that seemed to be related to the Rangpur lime rootstock. The behavior of Poncirus trifoliata and Rana~ur-1 lime as rootstocks for some sweet orange, grapefruit, and mandarin clones in the tests at the Limeira, RibeirSo Preto, and Tiet6 Stations gave us evidence that the "new disease" was caused by the exocortis virus (6).Olson and Shull (9),in Texas, and Reitz and Knorr (lo), in Florida, were able to confirm that thesis. Olson and Shull demonstrated also that Rangpur l&e shows xyloporosis symptoms when as a rootstock it has been budded with infected scion varieties. Grant et al. (3) reported later that they found xyloporosis symptoms on Rangpur- - lime in Brazil. This paper reports on additional studies made in Brazil on transmission of exocortis virus, symptomat~log~of affected trees, and the effects of the disease on fruit produc- tion. MATERIALS AND RESULTS Incubation Period in Young Trees. One hundred Rangpur lime seedlings were budded in the nursery in May, 1950, with clonal buds from the following varieties (20 each) : Bahianinha, Bargo, and Pera oranges, Marsh seedless grapefruit, and Eureka lemon. -
Plant Biometrics of Malay, Rose and Water Apple Guilherme Nacata1 & Renata Aparecida De Andrade2
ISSN 0100-2945 DOI: http://dx.doi.org /10.1590/0100-29452018131 Botanic and Physiology Plant biometrics of malay, rose and water apple Guilherme Nacata1 & Renata Aparecida de Andrade2 Abstract - Due to the lack of studies comparing Syzygium malaccensis(L) Meer & Perry, Syzygium aqueum Burm.f. and Syzygium jambos (L) Alston Syzygium in relation to the botanical genus Sygygium regarding the physical characteristics, the present research was conducted, aiming at biometrically characterizing each of the three species, as well as comparing them. The fruits were collected from the São Paulo State University (Unesp), School of Agricultural and Veterinarian Sciences, Jaboticabal. Syzygium plants were used for the evaluation of: fruit and seed masses (g); width and length of leaves (cm) and of seeds (cm); percentage of fruit pulp; length of leaf petiole (cm); and leaf area (cm2). Fifty fruits, leaves and seeds of each species were used, with 5 replicates of 10 samples each and the data were submitted to descriptive statistical analysis and organized into frequency tables. For comparative purposes among the species, a blocks randomized design was adopted, being analyzed by the Tukey Test at 5% of probability. The malay and water apple present fruits with high yield of pulp. The fruit of the malay apple are light, with narrow diameter, medium length, broad seeds, narrow and small leaves, with small leaf area. The rose apple fruit present medium mass, width and length, with broad seeds, narrow leaves, medium length and small leaf area. The water apple fruit are light, broad, long, without seeds, with broad leaves, long and having medium leaf area.
