“…In our study, we found that RWC decreased under salt stress, as also detected in the investigations by Eitel et al [36] and Boussadia et al [37]. RWC directly reflects the water status of plants, and its decrease suggests that salinity caused water deficit in plants.…”

“…The quantum yield of PSII is expected to be lowered when non-photochemical quenching (qN) increases, as qN is associated with a thermal deactivation of PSII excitation (Boussadia et al 2008;Weis and Berry 1987). However, our study did not support this expectation, as Yield was comparatively stable under moderate and high nitrogen conditions when qN increased.…”

“…F v /F m , Yield, Etr, qP and qN reflect the maximal quantum yield of PSII (Boussadia et al 2008), the practically quantum yield of PSII, the relative quantity of electrons passing through PSII during steadystate photosynthesis (Dai et al 2009;Tezara et al 2003), the proportion of PSII reaction centers that are open (Dai et al 2009;Maxwell and Johnson 2000), and the degree of plants efficiently-dissipated energy trapped at PSII in the form of heat (Wu et al 2008), respectively. It has been suggested that lower amounts of chlorophyll along with lower content of nitrogen can be the cause of lower basal F v / F m (Jiménez et al 2009).…”

Effects of nitrogen addition on growth and photosynthetic characteristics of Acer truncatum seedlings

Increasing levels of atmospheric nitrogen deposition have greatly affected forest trees. Acer truncatum Bunge has a large distribution in northern China, Korea and Japan and plays an important ecological role in forest ecosystems. We investigated the responses of A. truncatum to a broad range of nitrogen addition regimes with a focus on seedling growth, biomass partitioning, leaf morphology, gas exchange physiology and chlorophyll fluorescence physiology. Moderate nitrogen addition promoted shoot height, stem diameter at ground height, total biomass, size of leaves and chlorophyll fluorescence and gas exchange performance, whereas extreme level of nitrogen addition did not result in such facilitation. Chlorophyll content, pattern of biomass partitioning, ratio of leaf length to width, leaf water content, and specific leaf area did not change among the addition regimes. The critical amount of nitrogen deposition should be defined in the context of a certain time period in a particular region for a certain species at a special developmental stage. The critical amount of N deposition that weakens total biomass facilitation in A. truncatum planted in mixed soil of yellow cinnamon soil and humic soil is approximately 10 g N m −2 y −1 during the first growing season.

“…In agreement with the results of Angelopoulos et al (1996) showing that during the development of water stress a gradual decline of the ratio F v /F m occurred. Recently, Boussadia et al (2008) showed that F v /F m was reduced significantly in plants submitted to water deficit. Declining F v /F m values implies that photochemical conversion efficiency is altered and could indicate the possibility of photoinhibition (Ranjbarfordoei et al, 2006).…”

“…This positive correlation suggests that the reduction in maximal efficiency of PSII photochemistry particularly at drought stress may be due to factors affecting stomatal closure rather than to damages in the photosynthetic apparatus. In addition, increasing stomatal conductance to water vapor resulted in subsequent increase in the net photosynthetic rate under selenium spraying showed that stomata are the main limiting factor to carbon uptake (Cornic et al, 1992;Boussadia et al, 2008).…”

This paper reports the effects of selenium (Se) application on some physiological characteristics of barley (Hordeum vulgare L. cv. Rihane-03) exposed to drought stress. Foliar application to barley at 30 g selenium ha -1 , as sodium selenate, increased significantly shoot dry weight and relative water content in well-watered plants. A remarkable reduction in dry weight of water-stressed plants was associated with significant decrease in maximal efficiency of PSII (F v /F m ), stomatal conductance (g s ) and net CO 2 assimilation rate (A). Activity of antioxidant enzymes was increased by drought stress significantly. Amounts of malondialdehyde (MDA) and hydrogen peroxide (H 2 O 2 ) remained unchanged in Sesupplemented water-deficit plants obviously because of an efficient scavenging following significant enhancement of catalase (CAT) and glutathione peroxidase (GSH-Px) activities. These results indicate that an application of selenium was favorable for biomass accumulation of barley plants under well-watered conditions. However, it did not significantly affect dry matter accumulation under drought stress, but Se-supplemented water-deficit plants exhibited better protection from oxidative damage because of higher CAT and GSH-Px activities and lower level of lipid peroxidation. These results suggest that selenium application can improve antioxidant defense system under drought stress conditions, and it may be recommended for arid and semiarid regions.
