Study of secondary xylem of six species of the genus Citrus used in Costa Rica.

However, the exploitation of these plantations is limited only to the fruit, leaving many parts of the tree without a use, which they can be an important bioma...

However, the exploitation of these plantations is limited only to the fruit, leaving many parts of the tree without a use, which they can be an important biomass source for energy production. In the present work, it was studied the anatomy of the secondary xylem of six species of the genus Citrus: C. aurantifolia (limero), C. limettioides (sweet lemon), C. reticula (tangerine), C. paradisi (grapefruit), C. sinensis (orange) and a variety, C. sinensis var. Washington Navel (hybrid orange) by the anatomical description (macroscopic and microscopic) of their wood, with the aim of providing information for a future process of their trunk’s use. For this, there were taken samples of the trees’ trunks, which were described using international standards of wood description. The results showed that different Citrus species had a dry density wood less than 500 kg/m3, a fine to medium-sized texture, a pale yellow to yellow color, and no veined, flavor or scent. Also, the wood presented diffuse - porous and high abundance of solitary and small pores. There were observed homocellular rays, with a 1-3 cell width and 10-25 cell height. For axial parenchyma, it presented a wide variety of types, ranging from paratracheal to apotracheal, and some parenchyma bands forming false or either annual rings. The presence of traumatic canals and crystals in the species’ wood were also determined. Generally it was evident that the anatomy of the six studied species presented little difference between them, which it is why the difficultness of their possible identification. En Costa Rica, algunas especies del género Citrusson plantadas para la producción del fruto o comoárboles de servicio en cultivos de café (Coffea spp). Sinembargo, el aprovechamiento de estas plantaciones selimita solamente al fruto, por lo que al llegar al final de suvida útil, las partes leñosas del árbol son despreciadas,a pesar de ser una fuente importante de biomasa para laproducción de energía. En el presente trabajo se estudióla anatomía del xilema secundario de seis especies delgénero Citrus: C. aurantifolia (limero), C. limettioides(limón dulce), C. reticula (mandarina), C. paradisi (toronja),C. sinensis (naranja) y una variedad, C. sinensis var.Washington (naranja injertada), mediante la descripciónanatómica (macroscópica y microscópica) de la maderade estas especies, con el objetivo de aportar informaciónpara la utilización del fuste. Para ello, muestras del fustefueron descritas utilizando las normas internacionalesde descripción de madera. Los resultados mostraronque la madera de las especies de Citrus evaluadaspresentan una densidad seca menor de 500 kg/m3, textura fina a mediana, color amarrillo a amarrillo pálido,sin veteado, sabor u olor característico. Así mismo,mostraron porosidad difusa y poros solitarios, pequeñosy de alta abundancia. Se observaron radios de tipohomocelulares, de 1 a 3 células de ancho y de 10 a 25células en altura. Para el parénquima axial, se presentóuna gran variedad de tipos, que van desde paratraquealhasta el apotraqueal, y bandas de parénquima formandoanillos falsos o bien anillos anuales. La presencia decanales traumáticos y cristales en madera tambiénestuvieron presentes en todas las especies. En general,se evidencia que la anatomía de la madera de las seisespecies estudiadas presenta poca diferencia entreellas, por lo que su posible identificación a este nivel sedificulta. 2012-11-21 2021-06-08T22:00:53Z 2021-06-08T22:00:53Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion https://revistas.tec.ac.cr/index.php/kuru/article/view/489 10.18845/rfmk.v9i23.489 http://hdl.handle.net/2238/12571 spa https://revistas.tec.ac.cr/index.php/kuru/article/view/489/418 application/pdf Editorial Tecnológica de Costa Rica Revista Forestal Mesoamericana Kurú; Vol. 9 Núm. 23 (2012): Julio- Diciembre 2012; pág. 35-44 2215-2504 |

Some of the species of the genus Citrus are planted in Costa Rica for fruit production or as shadow trees in coffee (Coffea sp) plantations. However, the exploitation of these plantations is limited only to the fruit, leaving many parts of the tree without a use, which they can be an important biomass source for energy production. In the present work, it was studied the anatomy of the secondary xylem of six species of the genus Citrus: C. aurantifolia (limero), C. limettioides (sweet lemon), C. reticula (tangerine), C. paradisi (grapefruit), C. sinensis (orange) and a variety, C. sinensis var.
