“…However, it is consistent with the results of this work, different authors like Enjalbert et al (2013) state that the percentage content and fatty acid composition may vary with the species and the condition of drought; the authors found that two of three species assessed significantly reduced fatty acid content in drought as a direct result of the reduction in linolenic acid content and that other species that maintained high levels of this acid recorded higher levels of tolerance to drought (Enjalbert et al, 2013). pasto Estrella, por ser más adaptado a condiciones de suelos húmedos.…”

En estas condiciones y de acuerdo a Enjalbert et al (2013) B. decumbens Stapf puede aumentar y mantener diferencialmente la composición de los ácidos grasos poliinsaturados de membrana, tales como el ácido linolénico como estrategia para mantener fluidez en la membrana y mejorar el intercambio de agua hacia las células.…”

“…Sin embargo, de manera consistente con los resultados de este trabajo, diferentes autores como Enjalbert et al (2013), afirman que el contenido porcentual y la composición de los ácidos grasos puede variar con la especie y la condición de sequía; los autores encontraron que dos de tres especies evaluadas redujeron significativamente el contenido de ácidos grasos en sequía como una consecuencia directa de la reducción en el contenido del ácido linolénico y que la otra especie que mantuvo altos niveles de éste ácido registró mejores niveles de tolerancia a la sequía (Enjalbert et al, 2013).…”

Bromatología de Brachiaria decumbens Stapf y Cynodon nlemfuensisVanderyst en suelos sulfatados ácidos en Córdoba, Colombia* Bromatology of Brachiaria decumbens Stapf and Cynodon nlemfuensis ResumenLos suelos sulfatados ácidos generalmente se caracterizan por poseer altas concentraciones de Al, Fe, y Mn, en los que se aplica cal agrícola para disminuir el efecto fitotóxico de estos elementos y aumentar la disponibilidad de nutrientes como P, Ca, Mg, K y N. El objetivo del trabajo fue evaluar el efecto de diferentes dosis de cal sobre las características bromatológicas en dos especies de gramíneas forrajeras, Cynodon nlemfuensis Vanderyst (pasto Estrella) y Brachiaria decumbens Stapf, en suelos sulfatados ácidos. Se diseñó un experimento de bloques completamente al azar con estructura de sub-parcelas divididas, donde la parcela principal correspondió a la época (seca o húmeda), la sub-parcela a las especies de pasto y las sub-subparcelas a las dosis de encalamiento (0, 3, 6 y 9 t ha -1 de cal). Los resultados indicaron que en la época húmeda los pastos mantienen similares contenidos de proteína cruda, pero que en época seca, estos niveles se reducen en 20% (p≤0.01), en B. decumbens Stapf respecto al pasto Estrella. La época del año afectó el porcentaje de grasa en ambas especies (p≤ 0.01) registrando valores de 1.97% para pasto Estrella y 1.87 % para B. decumbens Stapf en época húmeda y de 1.96 y 2.64 respectivamente para las mismas especies en época seca. Independientemente de la dosis de carbonato de calcio aplicada, el porcentaje de fibra se aumentó significativamente AbstractAcid sulphate soils are generally characterized by having high concentrations of Al, Fe, and Mn, in which is applied agricultural lime to reduce the phytotoxic effects of these elements and increase the availability of nutrients such as P, Ca, Mg, K and N. The aim of the study was to evaluate the effect of different doses of lime on the bromatological characteristics of two species of forage grass, Cynodon nlemfuensis Vanderyst (African Bermudagrass) and Brachiaria decumbens Stapf in acid sulphate soils. A complete randomized block experiment was designed with a structure of divided sub-plots, where the main plot corresponded to season (dry or wet), the sub-plot to grass species and sub-subplots to lime doses (0, 3, 6 and 9 t ha -1 lime). The results indicated that during the wet season pastures maintain similar crude protein, but in dry season, these levels are reduced by 20% (p≤ 0.01) in B. decumbens Stapf compared to American bermuda grass. The time of year affects the percentage of fat in both species (p≤ 0.01)-recording values of 1.97% recorded for American bermudagrass and 1.87% for B. decumbens Stapf in wet season and 1.96 and 2.64 respectively for the same species in the dry season.

“…In particular, C. sativa can be grown on marginal land due to its characteristics such as cold-stress resistance and low fertilizer demands (Enjalbert et al 2013;Putnam et al 1993;Zubr 1997). C. sativa seeds contain 35-45 % storage oils per seed dry weight and its seed oils with high levels of unsaturated fatty acids are suitable for the production of jet fuels and biodiesel due to their physical properties such as lower melting point (Moser 2010(Moser , 2012Waraich et al 2013;Zubr 1997).…”

Crop cycles in spring canola (Brassica napus L.) and carinata (Brassica carinata A. Braun) are controlled by temperature and photoperiod. In the central region of South America, which accounts for 90% of South American rapeseed crop production, farmers seek to sow as early as possible to maximize yield even though early sowing dates expose crops to a higher probability of frost occurrence that had not been quantified before. Our objective was to model phenology for one spring cultivar of canola ('Rivette') and one of carinata ('Avanza 641') and assess the probability of frost occurrence during flowering and grain filling in the central region of South America. For the estimation of frost risk, we modeled phenology resulting from 15 April to 15 August sowing dates at 12 locations (from 31.16˚to 34.20˚S latitude). We assumed that the critical period spans from 100 to 500 growing degree days (GDD) after flowering. Under early sowing dates, carinata tends to have a longer cycle (200 GDD more than canola) although both crops had a similar cycle length under a late sowing date. Predicted and observed flowering dates showed an average difference of 1.6 and 0.95 d for canola and carinata, respectively. Carinata has a lower probability of suffering frost events, and early sowing dates result in a greater exposure to frost damage. The results of this work will enable farmers and stakeholders to know the potential frost risk when defining a sowing date for canola and carinata. INTRODUCTIONRapeseed crops are among the most important commodities, with an annual worldwide production of 723 million t in 2019-2020. Rapeseed ranks fourth among the most important oilseed crops produced globally, accounting for 6% of a world oil crop market largely led by oil palm (Elaeis guineensis Jacq.) and soybean [Glycine max (L.) Merr.] (FAOSTAT, 2020). Rapeseeds include canola (Brassica napus L.), an edible oil crop with low erucic acid and glucosinolates content Abbreviations: CCC, concordance correlation coefficient; GDD, growing degree days.
