Abstract
QUIROGA - CARDONA, Julio; HERNANDEZ- PARRADO, Francy L; SILVA- HERRERA, María del Rosario and ORDUZ-RODRIGUEZ, Javier O.. Performance of the production of Tahiti lime (Citrus latifolia Tanaka) grafted on the pattern of Cleopatra Mandarin (Citrus reticulata Blanco) and the influence of tristeza virus (CTV) under the piedemont of Meta, 1997-2008. Orinoquia [online]. 2010, vol.14, n.1, pp.5-15. ISSN 0121-3709.
Tahiti limes (Citrus latifolia T) is in third place among the citrus species cultivated in Colombia. Its fruits are consumed in the domestic market and has a growing export market. Among the viral diseases affecting citrus crops Virus Citrus Tristeza (CTV) is one of the most limiting for production and longevity of plants especially in Tahiti lime. This study was carried out under the ecological conditions of the Research Center Corpoica La Libertad, in the foothills of the department of Meta. The plants used in the nursery in 1996 grafted with buds from crops used as standard Cleopatra mandarin (Citrus reticulata Blanco). The crop field was established in 1997, occupying an area of one hectare, with a density of 490 plants ha-1. To determine crop production took annual records, and the incidence and severity of the (CTV) were two readings in plants, during the seventh and eleventh year after transplantation (addt). In 2008 (11 addt) A description of the symptoms of the damage caused by citrus tristeza in the plant and the photographic record was made. The Tahiti lime production started three years after transplantation with 4 t / ha and increased annually to present the peak of production in the eighth year with 62 t/ha, then decreased until 2 t/ha in year 11. The incidence of CTV in 2003 (6 addt) was 16.5 % for a total of 80 affected plants and in 2008 (11 addt) 100 % of plants were affected (490 plants). The severity of CTV, in the 2003 was 29.4 %, while the reading of 2008 was 84 %.
