“…Secondly, the sodium level in ANA was slightly lower (Figure 3b). The sodium levels most likely did not slow down the growth performance of the lettuce plants, as the concentration was far below the salinity threshold [25,26].…”

Abstract:The mobilization of nutrients from fish sludge (i.e., feces and uneaten feed) plays a key role in optimizing the resource utilization and thus in improving the sustainability of aquaponic systems. While several studies have documented the aerobic and anaerobic digestion performance of aquaculture sludge, the impact of the digestate on plant growth has yet to be understood. The present study examines the impact of either an aerobic or an anaerobic digestion effluent on lettuce plant growth, by enriching a mixture of aquaculture and tap water with supernatants from both aerobic and anaerobic batch reactors. The lettuce plants grown in the hydroponic system supplied with supernatant from an anaerobic reactor had significantly better performance with respect to weight gain than both, those in the system where supernatant from the aerobic reactor was added, as well as the control system. It can be hypothesized that this effect was caused by the presence of NH 4 + as well as dissolved organic matter, plant growth promoting rhizobacteria and fungi, and humic acid, which are predominantly present in anaerobic effluents. This study should therefore be of value to researchers and practitioners wishing to further develop sludge remineralization in aquaponic systems.

“…The chlorosis of older leaves (yellow and brown) is often associated with the toxic effects of chloride ions accumulation in leaves (Munns & Tester, 2008; Parida & Das, 2005). Following leaf death, plant growth was inhibited by the reduction of photosynthetic surface area and biomass (Stofberg et al, 2015).…”

“…Worldwide, many freshwater ecosystems have been experiencing increased salinity stress (Jolly, McEwan, & Holland, 2008; Stofberg, Klimkowska, Paulissen, et al, 2015). Climate change, anthropogenic activities and salt water intrusion from estuaries caused by decline of water discharge from the upriver basin greatly elevate freshwater salinity (Jeppesen et al, 2015; Werner, Bakker, Post, et al, 2013).…”

Many freshwater ecosystems are facing salinity stress, but limited information is available about its effects on submerged macrophytes. Here, we assessed the effects of salinity on sprouting and growth of three submerged macrophytes-Potamogeton crispus, Hydrilla verticillata and Myriophyllum spicatum. We conducted experiments in the lab and the outdoor platform to test for the sprouting and growth responses of selected macrophytes to a gradient of salinity (0.32-10,000 mg Cl − L −1). Sprouting rate, biomass and other related physiological indices were measured in all treatments. We found that lower salinity (100 mg Cl − L −1) increased the turion sprouting rate, and higher salinity (greater than or equal to 5,000 mg Cl − L −1) significantly inhibited the sprouting of P. crispus turions. M. spicatum appeared to have higher tolerance of salinity than H. verticillata. The optimum salinity for the growth of H. verticillata and M. spicatum was 500-1,000 mg Cl − L −1 and 100-500 mg Cl − L −1 , respectively. Activity of superoxide dismutase (SOD) and production of malondialdehyde (MDA) differed in salinity levels between submerged macrophytes, and higher SOD activity was observed in M. spicatum. This study helped clarify how physiological response mechanisms affecting sprouting and growth of submerged macrophytes are inhibited under high salinity and suggested that SOD plays an important role in the resistance to oxidative stress induced by salinity.

“…Plant uptake is generally dependent on the physical–chemical properties of the chemicals, the characteristics of soil and irrigation water, and the plant species and physiology (Paterson et al 1994 ). It has been known that the changes in environmental influences (such as salinity and temperature) may impact the physicochemical properties of compounds as well as the physiology of plants, consequently resulting in changes in contaminant uptake by plant (Stofberg et al 2015 ). To date, the uptake potential of PFASs by plant in salinity or temperature gradients is unclear.…”

Perfluoroalkyl substances (PFASs) have recently attracted increasing concerns due to their ubiquitous existence, adverse effects and persistence in environment. This study employed four perfluorinated carboxylic acids (PFCAs) to examine effects of salinity and temperature on the PFAS uptake in wheat, one of the major crops in the North China Plain. Wheat plants were grown in the spiked-PFCA hydroponic culture system at different salinities and temperatures. As expected, salinity and temperature significantly impacted the root uptake and translocation of wheat to four PFCAs, and the concentrations for each of PFCAs in wheat root and shoot increased with increasing salinity and temperature, respectively. PFCA concentrations at high salinity or high temperature were up to thrice those found at low salinity or low temperature. Except for perfluorobutanoic acid, the amount of PFCAs in root was always higher than that in shoot at the ranges of salinity and temperature tested. Additionally salinity and temperature were also capable of influencing the transfer factors (TFs) of four PFCAs, and significant increase was observed in the TFs in response to the increases in salinity and temperature.Electronic supplementary materialThe online version of this article (doi:10.1186/s40064-016-2016-9) contains supplementary material, which is available to authorized users.
