Análisis exploratorio en raigrás anual tetraploide para días a floración y rendimiento
(Asociación Argentina de Producción Animal, 2023-09)Entre las especies forrajeras de mayor importancia tanto en ambientes de alta productividad como marginales a la agricultura, se destaca el raigrás anual tetraploide (Lolium multiflorum Lam.). A pesar de ser una especie ... -
Changes in number and weight of wheat and triticale grains to manipulation in source-sink relationship
(Hindawi, 2019-01)The source-sink ratio experimental manipulation has helped to define whether a crop is limited by source or sink or co-limited by both. There is no evidence in triticale of source-sink manipulations effects on yield and ... -
Control de la floración en agropiro alargado : ¿compromiso entre cantidad y calidad del forraje?
(Ediciones INTA, 2019-04)El agropiro alargado tiene un valor nutritivo bajo y cambia de acuerdo a la época del año y el estado fenológico de la pastura. En relación a ello se presentan los resultados de un trabajo para evaluar la acumulación neta ... -
Cómo afectan los genes de sensibilidad al fotoperíodo PPD-1 al desarrollo del trigo a antesis?
(Ediciones INTA, 2018-04)La sensibilidad al fotoperiodo afecta la adaptación del trigo al ambienteal modifiar: (i) la fecha de antesis, (ii) la duración de las etapas vegetativa y reproductiva previas a antesis, y (iii) la generación de estructuras ... -
Evaluación de caracteres de interés agronómico en la generación F2 de híbridos intra e intervarietales de tomate (Lycopersicon esculentum Mill)
(Facultad de Ciencias Agrarias, Universidad Nacional de Rosario, 2003-03)El objetivo de este trabajo fue estudiar la segregación de los caracteres de interés agronómico en la generación F2 de los híbridos provenientes de un cruzamiento dentro de L. esculentum var. esculentum, y un cruzamiento ... -
Kernel weight responses to the photo-thermal environment in maize dent × flint and flint × flint hybrids
(American Society of Agronomy, 2021-02)Maize (Zea mays, L.) grain yield is assumed to be source limited during the flowering period but sink limited during grain growth; however, environmental restrictions during active grain filling may strongly affect final ... -
Photoperiod-sensitivity genes shape floret development in wheat
(2019-02)Lengthening the pre-anthesis period of stem elongation (or late-reproductive phase, LRP) through altering photoperiod sensitivity has been suggested as a potential means to increase the number of fertile florets at anthesis ... -
Post-grazing cutting management in tall fescue affects the sward structure, forage and liveweight production
(2019-09)Tall fescue is the main perennial grass of the pastures of the temperate region of Argentina. However, after flowering in spring, tall fescue loses productivity and quality. Based on this, the objective of this work was ... -
Predicting soybean development with a simple photothermal dynamic algorithm
(Asociación de la Cadena de la Soja Argentina, 2019-09)Predicting the occurrence of the critical period for soybean’s yield determination is important for farmers to decide on variety and sowing date with the objective to expose this period (during which yield is mainly ... -
Root phenotypes at maturity in diverse wheat and triticale genotypes grown in three field experiments: Relationships to shoot selection, biomass, grain yield, flowering time, and environment
(Elsevier, 2020-09)Modelling and limited data suggest that crops with deeper and longer roots capture more soil resources and yield more when water is available deeper in soil profiles. Interest has grown in the development of new cultivars ... -
The physiology and genetics behind fruiting efficiency, a promising spike trait to improve wheat yield potential
(Oxford University Press, 2021-03)The fruiting efficiency (FE, grains per g of spike dry weight at anthesis) was proposed as a promising spike trait to improve wheat yield potential, based on its functional relationship with grain number determination (the ... -
Wheat Ppd-1 allelic combination modulates photoperiod sensitivity
(Sociedad Argentina de Fisiología Vegetal, 2018-11)ABSTRACT: a model linking Ppd-1 allelic composition to photoperiod response curve would allow replacing expensive and time consuming phenologic trials. In Ppd-1 near isogenic lines grown under different photoperiods we ...
