“…The reduction in plant height could be attributed to lower crop growth rate and the decrease in relative water content. These results are in harmony with those of Nabipour et al, (2002), Bayoumi (2004), Mohamed (2004), Farhat (2005), Bagheri and Abad (2007), Samarah et al,(2009) andVaezi et al, (2010).…”

“…Moreover, the reduction in assimilates translocated to new developing tillers might owe much the death of the new tillers and depressed the number of spikes primordial. These results are confirmed by Abd El-Wahab (2002), Bayoumi (2004), Mohamed (2004), Farhat (2005), Mahmoud (2006), Bagheri and Abad (2007), Samarah et al, (2009) and Vaezi et al, (2010).…”

This study examined seven barley genotypes in two evaluation experiments; the 1 st under normal condition at Sakha station while the 2 nd under salt stress at the El-Hosinia station, during two growing seasons (. During 2017 season to study the efficacy of barley seed with characters under different salinity levels(0, 10, 12, 14 and 16 dSm -1 ) using Rashid salt. The randomized complete block design with 3 replications was used for each experiment. Nine traits were recorded, days to heading, days to maturity, plant height (cm), spike length(cm), No. of spikes m -2 , No. of grains spike -1 , straw yield (t. ha -1 ), grain yield (t.ha -1 ) and harvest index (HI). Other five traits were recorded in Laboratory experiment; shoot length, root length, seedling dry weight (g), K + content and N + a content. Besides, eight stress tolerance indices were evaluated (TOL, MP, STI, GMP, Yr, DSI, YSI, YI). The combined analysis of variance for years, locations, genotypes, and interaction was significant and highly significant for all studied traits; Results revealed that Line 4, Line 2 and line1 gave the highest values under two conditions in both seasons for grain yield (t.ha -1 ). For indices of salinity tolerance, the Productivity MP Values obtained by Line4; Line2; Giza123 and Line1. Moreover, these four tolerant genotypes recorded high values for GMP, STI, YSI, and YI. Significant differences were observed between salinity levels, whereas level (10dSm -1 ) was lowest harmful in connection. Compared with other Salinity levels. On the other hand, the highest harmful of parameters was obtained by Salinity level(16 dSm -1 ).

“…Under both water stress and irrigated conditions, L4 revealed the highest grain yield for two years. These results agreed with Bagheri et al (2007) Santos et al (2008) Samarah el al. (2009), Refay (2010 and Vaezi el al.…”

“…The reduction percentage was 41, 46 and 44% at the first season, the second and combined, respectively. These results are confirmed by Bayoumi (2004), Bagheri et al (2007) and Refay (2010). Biological yield differences were related to low plant height, leaf area and tiller numbers; grain yield differences were caused by a reduction in spikes/plant and grains/spike.…”

HIS STUDY was conducted to evaluate twenty covered barley (Hordeum vulgare L.) genotypes for high yield potential and stable performance under two irrigation treatments (irrigated and water stressed). Total dry matter accumulation (TDM), leaf area index (LAI), crop growth rate (CGR), net assimilation rate (NAR), relative growth rate (RGR), relative water content (RWC), relative chlorophyll content (RCC), grain yield and biological yield were evaluated during two successive seasons 2009/10 and 2010/11 at Sakha Res. Station. All parameters studied had a negative significant effects as a result of water stress in both growing seasons, except for relative chlorophyll content, which increased under stress conditions compared with the normal irrigation. Results showed that L4 and L8 genotypes had the heaviest biological yield and grain yield, where they had the highest values of TDM, LAI and CGR especially under stress condition, as well as possessed good values of NAR, RGR and RCC, revealing that these genotypes were more tolerant to water stress and more desirable genotypes for both stress and non-stress conditions.

“…But the effects of salinity treatment on sucrose phosphate synthase activities is weak under the condition of salt stress [17]. Salinity stress decreases starch content but increases sucrose content in four barley cultivars [2]. The amount of soluble carbohydrates in the roots and shoots sharply increased at higher salinities (more than 125 mM NaCl, Figs 3 and 4).…”

Salinity has adverse effects on plants and is one of the causes of environment degradation. Plants have developed many defensive mechanisms, protecting them from sodium chloride (NaCl), including accumulation of osmoprotective compounds, which maintain osmotic balance, protect cell structure and enzymes. In the current study, we investigated the effects of salinity resulting from a range of sodium chloride concentrations (from 0 to 400 mM) on the growth of common duckweed (Lemna minor L.) and yellow lupin (Lupinus luteus L.). Increasing concentration of sodium chloride decreased the area of common duckweed leaves. At the highest applied salt concentration, the decrease of leaf area was associated with leaf chlorosis. In yellow lupin, the increasing sodium chloride concentration inhibited root and stem elongation. The highest tested NaCl concentration of 400 mM completely stopped elongation of yellow lupin shoots. The content of cyclitols and soluble carbohydrates in plant tissues was evaluated as well. Cyclitols (D -chiro -inositol and D -pinitol), as well as soluble carbohydrates (glucose, fructose and sucrose) were detected in common duckweed tissues. Yellow lupin seedlings also contained cyclitols -D -pinitol, myo -inositol and D -chiro -inositol -and soluble carbohydrates -glucose, galactose and sucrose. The content of osmoprotectants in plant tissues, especially sucrose and cyclitols, increased with increasing concentration of sodium chloride in the soil. The results indicate that the content of cyclitols and soluble carbohydrates in plant tissues can be an indicator of plant response to salinity stress.
