“…As known, air pollution could cause serious oxidative damage such as DNA variation, lipid peroxidation, chlorophyll, protein degradation and photosynthesis reductions as revealed before (Weber-Lotfi et al 2002;Liu et al 2009). To cope with oxidative stress, plant develops a series of antioxidant enzyme and antioxidant pigment so as to safely degenerate free radicals in plant tissue (Liu et al 2007). In the present study, the higher ''Other protein N'' content under air pollution might be attributed to the elevated antioxidant enzyme content and activity, such as peroxidase and catalase, in Masson pine needles (unpublished data).…”

“…In Nanshan, the south suburb of Chongqing city in Southwestern China, there are about 2,000 ha of Masson pine forest which has exhibited decline since the beginning of the 1980s, and the damage to Masson pine trees was consistent with an increase in the atmospheric concentrations of SO 2 and fluoride (Bian and Yu 1992). Recent studies have found that this species had declined gradually during the latest decades in Dinghushan Biosphere Reserve and Baiyun Mountain in Guangdong province, by local acid rain and nitrogen deposition (Liu et al 2007;Lu et al 2010). SO 2 , NO x and heavy metal toxicity alter the normal growth of conifer tree species by changing amino acid contents and leaf nutrient balance, and both processes involve nitrogen metabolism in plant cells (Thelin et al 1998;Sun et al 2009).…”

“…They are widespread and useful for firewood and reforestation. The serious damage symptoms of S. superba affected by acid rain have been reported in some forests in China 14 . However, the knowledge of the mechanisms by which acid rain affects S. superba is limited.…”

“…The lack of nutrients or producing seedlings in inadequate containers can lead to physiological damage, as plants under stress activate alternative mechanisms to avoid damage in their photosynthetic apparatus, such as the dissipation of electrons by photorespiration (Genty et al, 1989;Arena et al, 2016) and thermal dissipation (Pinnola et al, 2013). The latter can be observed through increasing NPQ, described as a mechanism of PSII protection against photoinhibition (Liu et al, 2007). However, the effectiveness of the protective mechanisms depends on the stress intensity and physiological characteristics of the plant.…”
