Preselection of germplasm of Macroptilium lathyroides (L.) Urb. with shade-tolerance.

Studies of shade effects on native forage species support pre-breeding process and are useful to establish selection criteria in plant breeding programs for the agroforestry systems prevailing in the Argentine livestock production. In the present study, ecophysiological and agronomic traits were eva...

Studies of shade effects on native forage species support pre-breeding process and are useful to establish selection criteria in plant breeding programs for the agroforestry systems prevailing in the Argentine livestock production. In the present study, ecophysiological and agronomic traits were evaluated in accessions of Macroptilium lathyroides belonging to the germplasm bank “Ing. Agr. José M. Alonso” of the UNL, under both natural and artificial light conditions. The general response has been related to a shade-avoidance strategy, where plants showed longer stems and greater leaf area in detriment of root and leaf biomass. Even so, accessions without a significant stem and root biomass reduction under shading were identified. However, stomatal conductance and photosynthetic rate were affected on all accessions subject to shade, independently of the produced biomass relative to control.   El estudio de la respuesta al sombreado en especies forrajeras nativas es una estrategia de premejoramiento útil para la selección de los materiales adaptados a los sistemas productivos silvopastoriles, predominantes en la ganadería de cría bovina de Argentina. En el presente estudio se evaluaron caracteres agronómicos y ecofisiológicos en entradas de Macroptilium lathyroides del banco de germoplasma “Ing. Agr. José M. Alonso” de la UNL, en condiciones naturales y artificiales de luz y sombra. La respuesta general estuvo asociada a una estrategia de escape al sombreado, donde las plantas elongaron más los tallos y produjeron mayor área foliar en perjuicio de la biomasa radical y foliar. Sin embargo, se identificaron entradas cuya biomasa de tallo y raíz no sufrieron modificaciones significativas bajo sombra. No obstante, la conductividad estomática y la tasa fotosintética se vieron afectadas en todas las entradas en condiciones de sombra, independientemente de la biomasa relativa al testigo.   Universidad Nacional del Litoral 2021-04-28 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf application/octet-stream https://bibliotecavirtual.unl.edu.ar/publicaciones/index.php/FAVEAgrarias/article/view/10267 10.14409/fa.v20i1.10267 FAVE Sección Ciencias Agrarias; Vol. 20 Núm. 1 (2021): FAVE Sección Ciencias Agrarias; 229-245 FAVE Sección Ciencias Agrarias; Vol. 20 No. 1 (2021): FAVE Sección Ciencias Agrarias; 229-245 FAVE Sección Ciencias Agrarias; v. 20 n. 1 (2021): FAVE Sección Ciencias Agrarias; 229-245 2346-9129 1666-7719 10.14409/fa.v20i1 spa https://bibliotecavirtual.unl.edu.ar/publicaciones/index.php/FAVEAgrarias/article/view/10267/13612 https://bibliotecavirtual.unl.edu.ar/publicaciones/index.php/FAVEAgrarias/article/view/10267/13613 Derechos de autor 2021 FAVE Sección Ciencias Agrarias
