Growth, photosynthesis, and ion distribution in hydroponically cultured Populus alba L. cuttings grown under various salinity concentrations

Abstract: Growth, photosynthesis, and Na + , K + , and Ca 2+ distributions were investigated in 2-year-old hydroponically cultured Populus alba L. cuttings exposed to salt stresses (0, 0.85, 8.5, 17, and 85 mM NaCl in experiment 1 and 0, 50, 100, 150, and 200 mM in experiment 2) for 4 weeks in 2/5 Hoagland solution. Salt did not markedly inhibit height growth and diameter increment in 150 and 100 mM NaCl, respectively. The 85 mM NaCl treatment increased the dry weights of roots and total dry weight of plants, while 150 … Show more

“…For the determination of ion composition (Mao et al 2008), leaves and roots were powdered and digested in a solution of three acids (10:4:1, HNO 3 :HClO 4 :H 2 SO 4 ) at 200-350°C on a hot plate. The extracted solutions were used to determine the concentrations of Na ?…”

“…Salt accumulation in plant cells disrupts ion homeostasis and possibly causes deficiency of essential nutrients (Chartzoulakis 2005). These physiological difficulties result in leaf damage, including scorching, lower stomatal conductance, inhibition of photosynthetic activity, growth inhibition of shoots and roots, and in severe cases, high mortality of plants (Mao et al 2008). On the other hand, the route for salt entry in saline-submerged plants would be different from that in plants flooded with saline water (Wainwright 1984).…”

“…Plants can adapt to salinity by tolerating or avoiding salt uptake. Some plants can achieve salt tolerance by osmotic adjustment (Mao et al, 2008). Many researchers have studied salt tolerance of herbaceous plants after they are exposed to high salts.…”

“…When growing under saline conditions, plants may exhibit reduced leaf area, height, net photosynthesis, stomatal conductance, and transpiration, and may produce osmolytic compounds (Mao et al 2008). Flooding or waterlogging with seawater or freshwater is also a very important environmental stress worldwide and causes oxygen deficiency in the rhizosphere (Pierdomenico et al 2007).…”

“…Populus alba is native to northwest China, whereas Populus nigra is native to Europe but is widely distributed throughout China (Zheng 1983). There has been little research into the salt tolerance of these two species (Mao et al 2008), and much less into the interactive effects of salinity and oxygen deficiency in root systems in relation to flooding.…”
