Background Araucaria araucana is a mast species that presents a high variability in annual cone production. Researchers have recorded synchronization events in cone production in different populations, which allows the seed production to be concentrated, reducing the percentage of seeds consumed by different animal *** We sampled three populations located in the Andes Mountains, Araucanía Region, Chile. In 2004 we began the collection of data on cone production, for which we installed permanent plots（1200 m2each） at each location. We identified and labeled each female tree in each plot to monitor its cone production. In 2012 we selected a total of 30 trees near the plots to evaluate the number of seeds per cone. In each February from 2012 to 2014 we selected two mature cones and covered them with a porous mesh for subsequent collection and storage in March. At the beginning of June, we counted and weighed the seeds, determining the average weight, the number of seeds per cone, the germination capacity（GC）, and the germination speed（GS）.Results Cone production was synchronous across the three locations. We observed significant differences among the locations and years evaluated. The cones had fewer seeds in 2013（high production） compared to those in 2012（low production）, but their weights were similar. In 2014 the cones produced smaller seeds in fewer quantities. The difference between the years 2013 and 2014 resulted from the high-energy expenditure in 2013. Regarding GC and GS, there were significant differences among the three locations（GC: F = 45.41, p < 0.01; GS: F = 96.08, p < 0.01）, where the highest values were observed in *** Both GC and GS are related to seed weight but not to the number of cones produced in a given year. These annual fluctuations in seed production are determining factors in the population dynamics of forest species. Our results allow a better understanding of the reproductive phenology of A. araucana and could hel

The effects of the salt stress on plant growth are usually increased by the water stress. We studied the impact of both stresses in simultaneous pulses of drought and salinity on Paspalum dilatatum. This forage species is native to South America, spread in grasslands in many tropical, subtropical, and temperate areas of the world, and very common in grasslands of the Flooding Pampas of Argentina. Mimicking what happens in nature. We compared a pot experiment, a non-stressed control against water stress for a month (midpoint between field capacity and wilting point), and two saline stresses (moderate, 6 dSm-1 and strong, 12 dSm-1), also for a month. Aerial biomass (green leaf; non-leaf green material, and dry material) and roots were harvested, weighed, and analyzed for nitrogen, phosphorus, and cations. The biomass of all components significantly decreased when both stresses were applied. Water plus strong saline stress reduced by half the total biomasses, compared to the control. The proportion of aerial biomass/root biomass ratio as well as aerial green component/dry materials ratio tend to decrease when subjected to both stresses. Nitrogen concentration in plants was not significantly affected, but phosphorus concentration increased in aerial biomass components, from 0.10 to 0.18 mgkg-1 between the extreme treatments, but did not change in roots. Sodium concentration in plants increased (i.e., in green leave sodium (Na) increased from 0.27 to 2.01 mgkg-1 between the extreme treatments), whereas other cations either did not change or decreased, affecting the ratios between them. Sodium performance allows us to infer that the Na accumulation of P. dilatatum behaves in an intermediate range, compared to very tolerant to salts or non-salt tolerant species of the Paspalum genus. In agreement, when salts were applied in the form of a pulse, P. dilatatum tolerated higher salinity than that found by other authors for the sa
