Publicación Acceso abierto Evaluación de la eficacia de los métodos de mini injertos hendidura, t invertida y yema terminal en la propagación de plantas de naranja valencia (citrus sinensis (l.) osbeck.)(Universidad de Córdoba, 2020-11-11) Álvarez Correa, Cristian Camilo; Suárez Padrón, Isidro E.La Naranja Valencia (Citrus sinensis (L.) Osbeck.) es la más cultivada en las regiones citrícolas del mundo al igual que en Colombia, siendo las regiones subtropicales las responsables de más del 85% de la producción mundial. La Naranja Valencia es de gran importancia en Córdoba debido a su amplio consumo y además por sus altos contenidos nutricionales como la vitamina C, que ayuda a absorber otros nutrientes. En Colombia los pequeños productores de plantas para siembra del área citrícola, tienen la incapacidad de cumplir lo requerido por la Resolución 12816 de 2019, principalmente por los costos que implica el mantener plantas madres de gran tamaño bajo condiciones de casa malla. La presente investigación se realizó en el Laboratorio de Biotecnología Vegetal de la Facultad de Ciencias Agrícolas de la Universidad de Córdoba, municipio de Montería en el departamento de Córdoba y tuvo como objetivo principal evaluar la eficiencia de tres técnicas de mini injertación en la producción de plantas de naranja valencia.Publicación Acceso abierto Evaluación del crecimiento de plantas mini injertadas de naranja valencia (Citrus x sinensis osbeck) y lima Tahití (Citrus x latifolia Tanaka ex Q. Jiménez)(2023-07-05) Hoyos Villarraga, Julio Alejandro; Suárez Padrón, Isidro ElíasThe Citrus genus belongs to an important group of crops in the national and regional market that are used at an industrial level in a number of commercial products with high demand; Lately, in Colombia and especially in the department of Córdoba there has been a low production and therefore low commercialization of citrus fruits due to the presence of various pests that attack and affect these crops, many of them putting plant health at risk throughout the national territory such as Huanglongbing (HLB) which is produced by the bacterium Candidatus Liberibacter asiaticus using the insect Diaphorina citri as a vector. Due to this, the ICA (Colombian Agricultural Institute) has imposed the Resolution 12816 of August 21, 2019, which obligates nurseries to have a special infrastructure within their facilities in order to avoid contact of mother plants with insects vectors of diseases, but this generates a large economic investment to adapt all the necessary facilities to meet the requirements and be able to produce plant material. For these reasons, in Córdoba there are only two ICA-certified nurseries to market citrus, and nonnursery is certified to produce plants of this species. The IBAC (Institute of Applied Biotechnology of the Caribbean), in the search for technological alternatives to overcome these limitations, has evaluated the use of alternative methods of grafting through mini-grafts, considering as its main objective to evaluate the growth and development in the field phase of Tahiti lime (Citrus x latifolia Tanaka ex Q. Jiménez) and Valencia orange (Citrus x sinensis Osbeck) plants produced by two types of mini grafts. This research was carried out on the main campus of the University of Córdoba in a period of four months, the plant material consisted of plants propagated by mini slit grafts and inverted-T on rootstocks of Cleopatra mandarin (Citrus x reshni Hort. ex Tanaka), the evaluated variables corresponded to the number of branches per plant (1) and the height of these (2) measured every 20 days. The treatments were distributed using a completely randomized design (DCA) with a 2 x 2 x 2 factorial arrangement with 3 replicates. The first factor corresponded to the species, the second to the type of mini graft and the third to the type of container in the nursery. An analysis of variance (ANAVA) was carried out, which detected statistical differences in the variable number of branches, where Lima Tahiti produced a greater number than Valencia orange. In the height variable, there was a significant effect of species, type of mini graft, type of container, and in the species x container interaction, also observing statistical differences in the treatments of the factorial experiment vs controls for which the Dunnett test was performed at 5%.Publicación Acceso abierto Evaluación del crecimiento en etapa de vivero de plantas cítricas de naranja dulce (Citrus x sinensis (l.) osbeck (pro. sp.)) y lima tahití (Citrus x latifolia tanaka) producidas mediante dos métodos de mini enjertación y dos tipos de recipiente(2022-07-20) Uparela Gutiérrez, Yulisa Andrea; Suárez Padrón, Isidro E.Citrus (Citrus L.) are permanent crops with high adaptability to various climatic conditions, facilitating their cultivation in a large number of countries. Among the species with the highest commercial demand in Colombia are sweet oranges (Citrus x sinensis (L.) Osbeck (pro. sp.)) and Tahiti limes (Citrus x latifolia Tanaka). The national citrus market in recent years has shown a shortage in production; generated by the increase in pests and diseases, which has led to a reduction in plant material for new crops of citrus species, especially in the department of Córdoba, because of limitations to comply with regulations established by ICA through Resolution 12816 of August 21, 2019. To propose technical alternatives, IBAC (Instituto de Biotecnología Aplicada del Caribe) has evaluated the use of alternative methods of grafting through micro and mini grafts and evaluation of growth and development of propagated plants in the nursery stage, in order to accumulate information that allows delivering the appropriate recommendations. The present research (investigation) was carried out in the Plant Biotechnology Laboratory of the University of Córdoba and its main objective was to evaluate the growth and development in the nursery stage of citrus plants of sweet orange and Tahiti Lime produced through two methods of mini grafting, and transplanted in two types of container. The plant material consisted of plants produced from mini grafting of sweet orange and Tahiti lime. Bud donor plants were purchased from nurseries registered by the ICA. Two techniques were used for grafting: cleft and inverted Ton rootstocks of approximately 5-month age, grafted plants were kept tube and plastic bags, treatments were distributed with a CRD. The ANOVA allowed to detect the presence statistical differences in Tahiti lime plants in the variable increase in the number of leaves due to the interaction between type of grafting x container. In sweet orange plants increase in leaf number was affected by the type of grafting and container. Increase in stem umber of stems and increase in height were not affected for both species. The DMS test showed that Lima plants propagated by inverted-T 14 grafting and kept in bags developed a significantly higher number of leaves compared to those propagated by cleft grafting grown in bags. Sweet orange plants propagated by Inverted T grafting and transplanted in bags developed a significantly higher number of leaves compared to other treatments. Plastic bag and tube could be considered as container alternatives for transplanting depending on the characteristics of the nursery.
