Brassica oleraceae var. saberlica, a species native to eastern Turkey, arrived in Europe and spread to almost the entire world due to the particular flavor and nutritional content of its leaves (Tamashiro, 2017). It is rich in calcium, iron, vitamins and has anti-cancer substances, among other properties (https://www.magyp.gob.ar/). It is a winter leafy vegetable, with a biennial or multiannual cycle, robust, that tolerates cold temperatures below freezing point between -7 ° C to 27 ° C. In Argentina, studies carried out in Buenos Aires reveal yield results that oscillate between 3.1 and 6.7 tons/ha according to Logegaray (2018). It is characterized by having an erect, unbranched and elongated stem; in which numerous simple leaves, petiolate, oblong, with curly edges and glabrous, are inserted, which are arranged along the stem through an alternate spiral phyllotaxis. It presents flowers grouped in a racemose inflorescence. Its fruits are siliques, needing a vernalization process to flourish (Cartea González, 2008). The general objective of the present investigation was to compare morphoanatomical characters and the yield of two cultivars of Brassica oleracea var. Sabellica cv. 'Darkibor' and 'Redbor' (kale) in two planting dates in the School Field of the Faculty of Agricultural Sciences-UNC. As specific objectives, it was proposed to characterize the two cultivars exomorphologically during their cycle, to record different sowing times to determine optimal dates and better yields in the central region of the Province of Córdoba and to analyze associated foliar anatomical characters. The trial was carried out in the Experimental Field of the Faculty of Agricultural Sciences of the National University of Córdoba. The seeds used in the trial were purchased from the company Bejo (www.bejo.es). To obtain the specimens, sowing was carried out in germination trays. The early sowing was carried out at the end of May and the late sowing in mid-July, and in both cases the transplant was carried out when the seedlings reached the stage of 4 true leaves, in the months of July and September, respectively. The plots were arranged in completely randomized blocks with three repetitions per treatment (variety per planting season, leaving 6 treatments). Each plot was made up of three lines of 10 plants each. The plantation framework used was in borders of 0.50 m by 0.50 m, which determines a density of 40,000 plants/hectare. Both cultivars were characterized exomorphologically in the laboratory and in the field. For the analysis of the foliar anatomy, work was carried out in the Microscopy laboratory of the FCA-UNC, temporary and semi-permanent histological preparations were made from cross-sectionsof fresh leaves (water-glycerin 1:1 assembly), using traditional techniques and different stains ( D´Ambrogio de Argüeso, 1986; Gil, 2013). Nikon Alphashot-2 YS2 binocular optical microscopes were used and the corresponding photographic record was made with a 9.1 Megapixel Sony Cybershot DSC H50 and a 6 Megapixel Nikon Cool Pix S10 camera. The measurements for the exomorphological characterization were made on the 4 central plants of each row, whose height was measured (from the neck to the cauline apex), and 3 adult leaves per plant inserted in the 4th or 5th node below the apex, in which the width (in the middle part of the blade) and the leaf length (from the insertion of the petiole to the end of the blade) were measured. The leaves were harvested considering their size (15 to 20 cm long from the leaf base to the distal end of the leaf). Subsequently, the fresh weight was determined with a precision balance, thus obtaining the yield expressed in kg of fresh matter per ha. The data was statistically analyzed using the InfoStat program (Di Rienzo, et al. 2020). At 60 days from seeding, the determining photosynthetic parenchymal cells of the dorsiventral mesophyll differentiated. The cultivar 'Darkibor' has a better behavior in early planting dates, with respect to height and foliar development, being that 'Redbor' achieves similar values in the morphoanatomical parameters analyzed for both planting dates, determining greater plasticity when defining the same. The yield obtained in early planting date is similar for both cultivars. All these parameters determine that early sowing dates favor the development of the crop in both cultivars. According to the behavior and production obtained in the trials, the cultivation of "kale" adapts to the climatic and edaphic conditions of Córdoba, making it suitable for commercial production, obtaining the highest yields in the spring-summer season. |

Brassica oleraceae var. sabellica, especie originaria del este de Turquía, llegó a Europa expandiéndose a casi todo el mundo debido al particular sabor y contenido nutricional de sus hojas (Tamashiro, 2017). Es rica en calcio, hierro, vitaminas y posee sustancias anti-cancerígenas, entre otras propiedades (https://www.magyp.gob.ar/). Se trata de una hortaliza invernal de hoja, de ciclo bienal o plurianual, robusta, que tolera temperaturas frías bajo punto de congelamiento entre -7 ° C a 27 ° C. En Argentina, estudios realizados en Buenos Aires revelan resultados de rendimiento que oscilan entre 3,1 y 6,7 tn/ha según Logegaray (2018). Se caracteriza por poseer un tallo erecto no ramificado y alargado; en el que se insertan numerosas hojas simples, pecioladas, oblongas, con bordes rizados y glabras, que se disponen a lo largo del tallo a través de una filotaxis alterna espiralada. Presenta flores agrupadas en una inflorescencia racemosa. Sus frutos son silicuas, necesitando un proceso de vernalización para florecer (Cartea González, 2008). El objetivo general de la presente investigación fue comparar caracteres morfoanatomicos y el rendimiento de dos cultivares de Brassica oleracea var. sabellica cv. 'Darkibor' y 'Redbor' (kale) en dos fechas de siembra en el Campo Escuela de la Facultad de Ciencias Agropecuarias-UNC. Como objetivos específicos se planteó, caracterizar exomorfológicamente a los dos cultivares durante su ciclo, registrar diferentes épocas de siembra para determinar fechas óptimas y mejores rendimientos en la región central de la Provincia de Córdoba y analizar caracteres anatómicos foliares asociados. El ensayo se llevó a cabo en el Campo Experimental de la Facultad de Ciencias Agropecuarias de la Universidad Nacional de Córdoba. Las semillas utilizadas en el ensayo, fueron adquiridas a la empresa Bejo (www.bejo.es). Para la obtención de los ejemplares, se realizó una siembra en bandejas de germinación. La siembra temprana se realizó a fines del mes de mayo y la tardía a mediados del mes de julio y en ambos casos el trasplante se llevó a cabo cuando los plantines alcanzaron el estado de 4 hojas verdaderas, en los meses de julio y septiembre respectivamente. Las parcelas se dispusieron en bloques completamente aleatorizados con tres repeticiones por tratamiento (variedad por época de siembra, quedando conformados 6 tratamientos). Cada parcela se conformó por tres líneas de 10 plantas c/u. El marco de plantación utilizado, fue en bordos de 0,50 m por 0,50 m, lo cual determina una densidad de 40.000 plantas/hectárea. Se caracterizó exomorfológicamente ambos cultivares en laboratorio y a campo. Para el análisis de la anatomía foliar se trabajó en el laboratorio de Microscopía de la FCA- UNC, se confeccionaron preparados histológicos temporarios y semipermanentes de cortes transversales de hojas frescas (montaje agua-glicerina 1:1), empleando técnicas tradicionales y diferentes tinciones (D´Ambrogio de Argüeso, 1986; Gil, 2013). Se trabajó con microscopios ópticos binoculares Nikon Alphashot-2 YS2 y se realizó el correspondiente registro fotográfico con cámara Sony Cybershot DSC H50 de 9,1 Mega pixeles y Nikon Cool Pix S10 de 6 Mega pixeles. Las mediciones para la caracterización exomorfológica, se realizaron sobre las 4 plantas centrales de cada surco a las cuales se les midió la altura (desde el cuello hasta el ápice caulinar), y se eligieron al azar 3 hojas adultas por planta insertas en el 4º o 5º nudo por debajo del ápice, en las cuales se midieron el ancho (en la parte media de la lámina) y el largo foliar (desde la inserción del pecíolo hasta el extremo de la lámina). La cosecha de las hojas se realizó considerando su tamaño (15 a 20 cm de largo desde la base foliar hasta el extremo distal de la hoja). Posteriormente, se determinó el peso fresco con balanza de precisión obteniendo de esta forma el rendimiento expresado en kg de materia fresca por ha. Los datos se analizaron estadísticamente mediante el programa InfoStat (Di Rienzo, et al. 2020). A los 60 días desde la siembra se diferenciaron las células de parénquima fotosintetizantes determinantes del mesofilo dorsiventral. El cultivar 'Darkibor' tiene un mejor comportamiento en fechas de siembra temprana, con respecto a la altura y desarrollo foliar siendo que 'Redbor' logra valores similares en los parámetros morfoanatómicos analizados para ambas fechas de siembra, determinando mayor plasticidad a la hora de definir la misma. El rendimiento obtenido en fecha de siembra temprana es similar para ambos cultivares. Todos estos parámetros determinan que las fechas de siembra tempranas favorecen el desarrollo del cultivo en ambos cultivares. Según el comportamiento y la producción obtenida en los ensayos, el cultivo de “kale” se adapta a las condiciones climáticas y edáficas de Córdoba haciéndolo apto para su producción comercial, obteniendo los mayores rendimientos en la época primavero-estival.
