BAAD: A biomass and allometry database for woody plants.
(Ecological Society of America, 2015-05-01)Understanding how plants are constructed—i.e., how key size dimensions and the amount of mass invested in different tissues varies among individuals—is essential for modeling plant growth, carbon stocks, and energy fluxes ... -
Changes in leaf size and in the rate of leaf production contribute to cytokinin-mediated growth promotion in Epipremnum aureum L. cuttings
(2013)The growth of ornamental foliage plants is often limited by pot size, which exerts a restriction on root growth and, therefore, on the production of root-synthesised cytokinins which play key regulatory roles in the ... -
Contrasting effects of phosphorus and potassium deficiencies on leaf area development in maize
(Crop Science Society of America, 2018-10)Management of P and K in agricultural systems is similar, since both move mainly by diffusion in soil. In maize (Zea mays L.), radiation capture is a consequence primarily of leaf area formation and senescence, but little ... -
Deficiencias de fósforo y potasio en maíz : efectos sobre el área foliar, crecimiento y absorción de nutrientes
(Facultad de Agronomía, Universidad de Buenos Aires, 2015-08)El manejo agronómico del fósforo (P) y del potasio (K) guarda similitudes, en gran medida por su baja movilidad en el suelo. Hay pocos estudios que aborden los procesos que se ven afectados en el cultivo de maíz (Zea mays ... -
Desarrollo y evaluación de métodos prácticos no destructivos para la estimación del Área Foliar (AF) por árbol y cálculo del Índice de Área Foliar (IAF) en montes de cerezo (Prunus avium L.)
(EEA Alto Valle-Università degli studi di Bologna, 2010-11)El conocimiento del Índice de Área Foliar (IAF) de los montes de cerezo (Prunus avium L.) es una herramienta de suma utilidad para la estimación del potencial productivo. Sin embargo, su medición es muy dificultosa, por ... -
Effects of combined or single exogenous auxin and/or cytokinin applications on growth and leaf area development in Epipremnum aureum
(2015)We have analysed the effects of combined auxin and cytokinin treatments on whole plant growth and leaf development in Epipremnum aureum and compared both morphological and physiological variables to those obtained with a ... -
Effects of plant density in broccoli on yield and radiation use efficiency
(Elsevier, 2006)The effects of plant density on broccoli (Brassica oleracea L. var. italica Plenck) commercial characteristics are well determined. However, it is not completely clear how the broccoli plant respond to changes in plant ... -
An empirical model that uses light attenuation and plant nitrogen status to predict within-canopy N distribution and upscale photosynthesis from leaf to whole canopy
(2015-10-03)Modelling the spatial and temporal distribution of leaf nitrogen (N) is central to specify photosynthetic parameters and simulate canopy photosynthesis. Leaf photosynthetic parameters depend on both local light availability and ... -
Exogenous cytokinin promotes Epipremnum aureum L. growth through enhanced dry weight assimilation rather than through changes in partitioning
(SCIENCEDOMAIN international, 2015)Aims: Benzylaminopurine (BAP) sprays have been shown to increase leaf size and leaf appearance rate, as well as biomass accumulation in pot-grown Epipremnum aureum L. BAP-mediated enhanced growth could either be the ... -
Impacto de las enfermedades foliares sobre variables fisiológicas determinantes del rendimiento del girasol ante diferentes situaciones de cultivo
(Gerencia de Comunicación e Imagen Institucional, DNA SICC, INTA, 2018-12)La mancha de la hoja por Alternaria (ALT) y la mancha negra del tallo por Phoma (MNT) son enfermedades foliares endémicas del girasol en Argentina. MNT disminuye regularmente el rendimiento del girasol de alto potencial ... -
Leaf senescence and the profile of expanded leaf area in maize (Zea mays L.)
(University of Guelph, 2002-08)Leaf senescence is a major factor affecting light interception and dry matter accumulation during the grain-filling period. Reduced leaf senescence has been associated with maize yield genetic improvement. The objectives ... -
Physico-chemical properties of plant cuticles and their functional and ecological significance
(2017-11)Most aerial plant surfaces are covered with a lipid-rich cuticle, which is a barrier for the bidirectional transport of substances between the plant and the surrounding environment. This review article provides an overview ... -
Producción de lechuga (Lactuca sativa) en hidroponía en sistema Indoor con luces artificiales = Lettuce (Lactuca sativa) production in hydroponics indoor system with artificial lights
(Universidad Nacional de la Patagonia Austral, 2023-12-21)En la localidad de Río Gallegos, el fotoperiodo disminuye en época invernal y lo torna limitante para la producción de hortícolas. Motivo por el cual, para obtener cultivos todo el año en esta zona, es necesario realizar ... -
The application of K phosphites to seed tubers enhanced emergence, early growth and mycorrhizal colonization in potato (Solanum tuberosum)
(Scientific Research, 2014-01)Rapid emergence and a vigorous growth prevent the seed tubers from infections by soil microbes and allow a rapid interception of solar radiation. In this work, the effect of the potassium phosphites (KPhi) applied to seed ... -
Vegetative and reproductive plasticity of broccoli at three levels of incident photosynthetically active radiation
(2007)To study the effects of shading on the growth, development, dry matter partitioning, and plant architecture of broccoli, "Legacy" hybrid plants were grown in pots in a greenhouse under black shading meshes to generate ...
