“…In addition, a high CO 2 concentration improves the growth and number of fine roots, which helps plants to absorb more water and nutrients. In our study, high CO 2 significantly increased the leaf area of plants, which may be an effect of increased photosynthesis under high CO 2 concentration . Improved growth under a high CO 2 concentration may ultimately help weeds establish and expand their ranges .…”

“…El seguimiento de la fenología del cultivo en las distintas fechas de siembra se realizó in situ, mediante el registro de la fecha de ocurrencia en días calendario de las principales etapas fenológicas del cultivo (Boote, 1982). Esas etapas fueron, además, referenciadas cronológicamente en grados día (°Cd), calculados con la ecuación lineal de tiempo térmico (TT) empleando una temperatura base (Tb) de 10,3ºC (Kumar et al, 2012).…”

“…En este sentido, otros autores (Collino et al, 2001;Haro et al, 2007b) señalan que el crecimiento, principalmente en las últimas etapas del ciclo del cultivo, responde altamente a la actividad de los destinos de fotoasimilados (frutos). Además, se han reportado mayores tasas de fotosíntesis neta en diferentes cultivares de maní bajo temperaturas de 35/30ºC (día/noche) comparadas con tratamientos a temperaturas menores (25/20ºC día/noche) (Kumar et al, 2012).…”

“…Los resultados obtenidos en el presente estudio indican que el rendimiento fue significativamente influenciado por la fecha de siembra en ambos ciclos experimentales (Cuadro 3). El retraso en la siembra desplaza el periodo reproductivo del cultivo hacia condiciones declinantes de radiación y temperatura que inciden negativamente en los procesos involucrados en la determinación del rendimiento (Cirilo y Andrade, 1994;Kumar et al, 2012). Retrasar la fecha de siembra en este trabajo produjo una disminución significativa del peso individual del fruto, al igual que lo hallado por Chandrika et al (2008) y Prathima et al (2012); pero, contrariamente a lo señalado por otros autores (Haro et al, 2007b), no se detectaron cambios significativos en el número de frutos maduros por planta.…”

“…Estos escenarios sub-óptimos están configurados por la extensa longitud del ciclo de los cultivares utilizados (>150 días) (Gamba et al, 2014) y el alto requerimiento de temperatura del maní con óptimos entre 25 a 30°C (Kumar et al, 2012). A ello se suma la frecuente ocurrencia de precipitaciones en el otoño y un descenso concomitante de la radiación incidente y la temperatura, que afectan negativamente el llenado de frutos (Giayetto et al, 2006).…”

Crop management practices like the choice of sowing date and of the cultivar modify and affect the environmental conditions of radiation and temperature in which peanut crop grows and develops. The aim of this study was to evaluate the effect that three contrasting sowing dates (SD) had on the growth and partition of biomass of two peanut cultivars of different cycle length; in the peanut-region of Rio Cuarto, Córdoba (Argentina). The experiment was conducted under field circumstances, without restrictions in water, nutrition or sanitary conditions during 2009/10 and 2010/11 growing season in the experimental field of the FAV-UNRC. On a Typical Haplustol soil with a clear light sandy texture. The Granoleico cultivars (runner type with cycle> 155 days) and Utre cultivars (cross runner x Spanish cycle of 130-140 days) were sown in early October, November and December (1st, 2nd and 3rd SD, respectively). During the growth cycle, environmental conditions were recorded, ecophysiological variables of development (phenology, thermal date) and growth (radiation interception, crop growth rate, biomass partitioning factor) of the crop were determined. At harvest, the yield components and market quality were determined, and the conditions to which the crop was exposed were analyzed. The phenological stages of peanut occurred in different environmental regimen due to variations in cycle length of the cultivars, sowing dates and the interaction between these variables. During the early SD, the duration of the cycle was longer, obtaining a greater amount of radiation as compared to the other SD. Both parameters, duration of the cycle and intercepted radiation (IPAR), decreased with late sowing. By delaying the SD, the crop growth rate (CGR) is greater during the initial periods of the crop cycle; an anticipation in the moment of maximum CGR can be seen, changes that occur in response to increased temperature and incident radiation (PAR), reflected in the pattern of biomass production and partition to the different plant organs. The combination of the SD and the length cycle of the cultivars affected the location of the critical period of definition of the yield components and the amount of radiation obtained by the crop. Particularly, the weight of ripe pod and grains was affected, which decreased by delaying the SD, with similar behavior in both cultivars and years of study. As a result, the pod yield and market quality is reduced with the delay of sowing date in both cultivars.

PremiseTo survive climate change and habitat loss, plants must rely on phenotypic changes in response to the environment, local adaptation, or migration. Understanding the drivers of intraspecific variation is critical to anticipate how plant species will respond to climate change and to inform conservation decisions. Here we explored the extent of local adaptation and phenotypic plasticity in Heteromeles arbutifolia, toyon, a species endemic to the California Floristic Province.MethodsWe collected leaves from 286 individuals across toyon's range and used seeds from 37 individuals to establish experimental gardens in the northern and southern parts of toyon's range. We measured leaf functional traits of the wild‐collected leaves and functional and fitness traits of the offspring grown in the experimental gardens. We then investigated the relationships between traits and source environment.ResultsMost traits we investigated responded plastically to the environment, and some traits in young seedlings were influenced by maternal effects. We found strong evidence that variation in leaf margins is a result of local adaptation to variation in temperature and temperature range. However, the source environment was not related to fitness traits or survival in the experimental gardens.ConclusionsOur findings reiterate the adaptive role of toothed leaf margins in colder and more seasonally variable environments. Additionally, we provide evidence that fitness of toyon is not dependent on where they are sourced, and thus toyon can be sourced across its range for restoration purposes.
