“…Under NH 4 ? stress, most plants showed slow growth rates, low root:shoot ratios, and occasionally had rotted roots and stems with chlorosis in old leaves (Britto and Kronzucker 2002;Tylova et al 2008;Jampeetong and Brix 2009). Thus, NH 4 ?…”

The effects of high NH(4)(+) concentration on growth, morphology, NH(4) (+) uptake and nutrient allocation of Myriophyllum brasiliense were investigated in hydroponic culture. The plants were grown under greenhouse conditions for 4 weeks using four levels of NH(4)(+) concentration: 1, 5, 10 and 15 mM. M. brasiliense grew well with a relative growth rate of c.0.03 day(-1) at NH(4)(+) concentration up to 5 mM. At the higher NH(4)(+) concentrations the growth of the plants was stunted and the plants had short roots and few new buds, especially when grown in 15 mM NH(4)(+) where the submerged leaves were lost and there were rotten roots and submerged stems. To avoid NH(4)(+) toxicity, the plants may have a mechanism to prevent cytoplasmic NH(4)(+) accumulation in plant cells. The net uptake of NH(4)(+) significantly decreased and the total N significantly increased in the plants treated with 10 and 15 mM NH(4)(+), respectively. The plant may employ NH(4)(+) assimilation and extrusion as a mechanism to compensate for the high NH(4)(+) concentrations. However, the plants may show nutrient deficiency symptoms, especially K deficiency symptoms, after they were exposed to NH(4)(+) concentration higher than 10 mM. The present study provides a basic ecophysiology of M. brasiliense that it can grow in NH(4)(+) enriched water up to concentrations as high as 5 mM.

“…Physiological stress resulting from high NH 4 + concentrations in water column may also contribute to the decline of macrophytes (Smolders et al, 1996b(Smolders et al, , 2000Nimptsch and Pflugmacher, 2007). High water column NH 4 + concentrations reduce growth of Ceratophyllum demersum and disturb carbon and nitrogen metabolism in Potamogeton crispus and Stratios aloides (Best, 1980;Smolders et al, 1996bSmolders et al, , 2000Cao et al, 2004;Tylová et al, 2008). Storage of excess nitrate in Littorella uniflora tissues was also found to reduce plant growth (Robe and Griffiths, 1994).…”

“…Reed plants were found to be more tolerant to N, P, K, ammonium compounds as well as to salt stresses as compared to Glyceria plant [108]. This was reflected by the growth of reed roots to greater soil depth, where the accumulation of NH 4 + ions was evident, which improved reed plant tolerance to mechanical damage, mowing, and grazing [108].…”

“…This was reflected by the growth of reed roots to greater soil depth, where the accumulation of NH 4 + ions was evident, which improved reed plant tolerance to mechanical damage, mowing, and grazing [108]. Unamuno et al [107] investigated reed plants' copper adsorption and reported that initial adsorption of Cu was high in the plants vegetative litter; but after 50 min, it decreased drastically.…”

“…PA plants are aquatic perennial grass [103]. A number of studies have been conducted on PA plants growth and development [104], mineral content [105], response to heavy metals [49,104,[106][107][108], response to salt stress, [108,109] as well as the different reed plant subspecies phenotypic, genotypic, evasive characteristics [49,96,109]. The results on the available research studies indicated that reed plant species significantly differ in their response to salt stress [102,109,110], this could be due to genotypic differences [103,111].…”

Advances in Bioremediation and Phytoremediation

View full text Add to dashboard Cite

Water pollution has been a growing issue for the last decades. This is mainly because of the boost in human population, and the motivations that lead to technological advances for the welfare of the society. Water pollution originates from different sources such as agricultural, municipal, industrial, and landfills drainage waters. These pollutants, which are either organic, nutrient, or heavy metals pollutants, are very deleterious to the natural ecosystems and eventually harmful to humans. Different procedures have been proposed for handling heavy metals water pollution, which encompass electro-osmosis, ion exchange, electrokinetic, sludge activation, as well as phytoextraction. Water contaminants are also removed using flotation, membrane filtration, aeration, precipitation, coagulation-flocculation, ion exchange, and electrochemical treatment. These procedures are costly and have prompted the use of other techniques, such as phytoremediation. Phytoremediation involves the utilization of plant species to alleviate the impacts of environmental pollution. It could be implemented to eliminate pollutants from various natural ecosystems including water, soil, and air or to develop new vegetation growth on disturbed or barren ground. Different plant species have been used for phytoremediation. This chapter addresses trace elements pollution of natural water resources in details and the abilities of Aquatic plant communities such as Reed plants (Phragmites australis) to absorb soluble trace elements from water.
