    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.

The new growth and flowers are flushed with purple and the trees are sensitive to frost. • Ethrog or Etrog citron is a variety of citron commonly used in the Jewish Feast of Tabernacles. The flesh is pale yellow and acidic, but not very juicy. The fruits hold well on the tree. The aromatic fruit is considerably larger than a lemon. • The yellow rind is glossy, thick and bumpy. Citron rind is traditionally candied for use in holiday fruitcake. Ethrog or Etrog citron CITRON Citrus medica • Buddha’s Hand or Fingered citron is a unique citrus grown mainly as a curiosity.

    A New Graft Transmissible Disease Found in Nagami Kumquat L

    A New Graft Transmissible Disease Found in Nagami Kumquat L. Navarro, J. A. Pina, J. F. Ballester, P. Moreno, and M. Cambra ABSTRACT. An undescribed graft transmissible disease has been found on Nagami kumquat. Three types of symptoms have been observed: 1) vein clearing on Pineapple sweet orange, Troyer citrange, sour orange, Marsh grapefruit, Orlando tangelo, Dweet tangor and Alemow, but not on Mexican lime, Etrog citron, Cleopatra mandarin, rough lemon, Eureka lemon, Volkamer lemon, trifoliate orange, Nules clementine and Parson's special mandarin; 2) stem pitting on Etrog citron, but not on the other species and hybrids; and 3) graft incompatibility of Nagami kumquat on Troyer citrange, but not on rough lemon. Vein clearing symptoms were more severe in seedlings grown at 18- 25OC than at 27-32OC. Stem pitting was induced only at 18-25OC. Some kumquat plants obtained by shoot-tip grafting in vitro were compatible with Troyer citrange, and did not induce vein clearing, but still produced stem pitting. These data suggest the presence of more than one pathogen on the original plants. Preliminary electron micro- scopy studies have shown the presence of some virus-like particles about 800 nm long in extracts of infected Troyer citrange and sweet orange plants. Diseased kumquats gave negative reactions by ELISA using four different tristeza antisera.

    Studies on Citrus Pollination Using Gamma-Irradiated Pollen

    s. AfT. J. Bot. , 1988, 54(3): 257-264 257 Studies on Citrus pollination using gamma-irradiated pollen J.H. de Lange* and A.P. Vincent Citrus and Subtropical Fruit Research Institute, Nelspruit, 1200 Republic of South Africa 'Present address: National Botanic Gardens, Private Bag 7, Claremont, 7735 Republic of South Africa Accepted 10 December 1987 Studies have been performed in Citrus motivated by Pandeys' theory of induced egg transformation and parthenogenetic development of embryos by pollination with irradiated pollen. Poncirus trifoliata (a Citrus relative) and shaddock pollen still germinated following 1,0 kGy irradiation and that of Palestine sweet lime following 2,0 kGy irradiation. The pollination study involved cross-pollination of Clementine mandarin using P. trifoliata or Palestine sweet lime pollen; gamma-irradiated at different doses, with or without a second pollination of the same flowers using normal Valencia sweet orange pollen. Using 0,5 or 1,0 kGy-irradiated P. trifoliata pollen, cross-pollination of Clementine, known for its limited parthenocarpic ability, resulted in the production of large numbers of seedless fruits. It was demonstrated that extensive embryo abortion took place after cross-pollination using irradiated pollen but that fertilization and/or early ovule development stimulated set and growth of fruitlets. Ovule occupation by irradiated pollen largely prevented fertilization by normal pollen. Pollination, using 0,5 or 1,0 kGy-irradiated pollen followed one day later by a second normal pollination is suggested for further studies on possible transformation of hybrids by the first pollen parent. Seed production after pollinating with pollen irradiated at high doses in a single pollination, is very low.

    The Clementine Was Named in 1902 After a Monk Living in Algeria, Father Clement Rodier. Father Clement Was Believed to Ha

    History/Origin The Clementine was named in 1902 after a monk living in Algeria, Father Clement Rodier. Father Clement was believed to have discovered the Clementine in his mandarin garden at his orphanage. Others think the Clementine originated earlier in Asia. Clementines were introduced to the United States in 1909 in Florida, and brought to California in 1914. Clementines are imported from Spain, Morocco, North Africa, South Africa and Chile. Botanical The Clementine is part of the citrus family. It is the fruit of a variety of Mandarin. Clementine oranges grow on trees. The fruit looks like a mini orange. They are considered the tiniest in the Mandarin orange family. The Clementine is a cross between a sweet orange and a Chinese mandarin orange. Clementines are sometimes mistaken for tangerines but the Clementine has a more easily removed skin, a sweeter fruit, and no seeds (usually). Nutrition Although in small packages, Clementines pack a BIG health punch. They are an excellent source of vitamin C, which: helps to heal wounds, and keeps teeth and gums healthy.
