“…Higher medium salinity hampers the photosynthetic capacity and chlorophyll synthesis of plants (Eleiwa et al, 2011;Mahboob et al, 2016). In this study, similar decline was found in photosynthetic pigments when seedlings exposed to NaCl, as reported in other crops like rice (Cha-Um et al, 2010), tomato (Taffouo et al, 2010) and wheat (Mahboob et al, 2017). The common reason of chlorophyll reduction is increase synthesis and/or activity of chlorophyllase enzyme (Moharekar et al, 2003).…”

Salicylic acid (SA) is a plant signaling molecule, which regulates various metabolic processes and involves in eliciting specific responses against abiotic/biotic stresses. Present study investigated the effect of SA on seed germination and seedling growth of salt stressed wheat. Wheat seeds were primed with water and two concentrations of SA (0.5 and 1.0 mM) for 12 h. For In-vitro experiment, seeds were soaked in 0, 50 and 100 mM NaCl solutions and seed germination and seedling growth parameters were studied. Primed seeds (both 0.5 and 1.0 mM SA) significantly improved seed germination, rate of germination, total chlorophyll, soluble sugars, proteins and phenolic content, as compared to non-primed and hydro-primed controls. For greenhouse experiment, hydro-primed (control) and SA primed (0.5 and 1.0 mM) seeds were grown in plastic pots and irrigated with 0 and 100 mM NaCl for 4 weeks. Plants emerged from SA primed seeds showed better response to salinity in which higher contents of photosynthetic pigments, soluble sugars, proteins and phenols contributed to enhanced growth and biomass production, as compare to control plants. Seed priming with 1.0 mM SA was found most effective to protect plants from damaging effects of salinity as compare to hydro-priming and 0.5 mM SA priming. Therefore, it is suggested that the priming of seeds with 1.0 mM SA can be adopted as a strategy to enhance wheat growth especially in salt affected soils.

“…Salt stress is one of the major abiotic threats causing major reductions in growth and productivity of edible crops like wheat (Panta et al, 2014;Mahboob et al, 2017). Increasing population and severity of environmental stresses impose enormous pressure to agricultural production (Egemberdieva et al, 2010).…”

“…From results, it was inferred that the values of crude protein (CP), digestible crude protein (DCP), ash and fat (%) in different organs of fodder beet plants, significantly decreased with applied irrigation water from Hadous drain compared to using El-Salam Canal irrigation water while proline content (in top organs) and crude fiber (CF) in fodder beet organs, took an opposite trend .This reduction in yield quality values may due to the high salt content of soil as well as salinity and sodicity of irrigation water of Hadous drain region. The present results are in harmony with those obtained by Abbas et al (2013) and Mahboob et al (2017) who concluded that salinity resulted in a significant reduction of the protein and fat contents.

To study the interaction effects of humic acid rates (HA) × irrigation water quality on productivity of fodder beet yield (Beta vulgaris L.) and its quality as well as some soil chemical properties, two field experiments were conducted in a split plot design with three replications in two different locations, El-Salam canal and Bahr Hadous drain in Sahl El-Hossinia, Sharkia Governorate, Egypt during to winter seasons (2014/2015 and 2015/2016). The studied factors were four rates of humic acid (0, 800 , 1600 and 2400 ml HA for 400 l-1 of irrigation water i.e., 0,2, 4 and 6 ml HA l-1 , respectively) and two types of irrigation water (El-Salam canal water 1.75 dSm-1 and Bahr Hadous drain water 3.31 dSm-1). The results indicated that using each of irrigation water and humic acid rate gave the best values of all the studied characters in El-Salam canal region compared to that obtained from Bahr Hadous drain region. Concerning the interaction effect (El-Salam canal irrigation water × HA 6 ml l-1 rate) recorded the maximum values for all studied characters: growth attributes (root length, root diameter, fresh weight (FW), dry weight (DW), fresh yield (FY), dry yield (DY), total fresh yield (TFY) and Total dry yield (TDY) and total chlorophyll), yield quality crude protein (CP), digestible crude protein (DCP), CF, ash, fat (%) in different organs and proline in top organs of fodder beet plants) and chemical composition (N, P, K, Fe, Mn and Zn concentrations and uptake) of fodder beet yield as well as some soil chemical properties (pH, EC, CEC, macro and micronutrients contents).

“…Breeders select for many traits in their efforts to improve adaptation to biotic and abiotic stress (Qin et al, 2013;Cao et al, 2017;Mahboob et al, 2017). An important consideration is agronomic type whereby initial selection is for an ideotype where plant height and grain yield are optimal for the target environment (Rebetzke et al, 2002;Rebetzke et al, 2012).…”

Wheat is an important cereal crop and one of the sources of nourishment and energy for humankind. But drought has affected wheat production seriously. This study has focused on wheat yield-related traits and tried to select suitable indexes for wheat breeding in semi-arid region. To this aim, a factorial experiment with two water regimes in field conditions was conducted. We found that the wheat line with higher grain yield also possessed higher spikelet number per spike (SN), 1000-kernel weight (TKW), and grain number per spike (GNPS) and the higher post-anthesis photosynthetic rate (Pn) than the others (P<0.05). The statistical analysis showed that under drought condition the higher grain yield was significantly associated with SN, TKW, GNPS and the higher post-anthesis Pn (P<0.05). Based on our findings, it is concluded that the post-anthesis Pn as physiological index and SN, TKW, and GNPS as agronomic trait are suitable in using selection indicators for wheat breeding in semi-arid region.

Abstract: A glass house experiment was conducted to investigate the potential of different wheat genotypes for physiological traits, decisive for their salt tolerance. Ten wheat genotypes along with salt tolerant check (LU-26s) were evaluated under two salinity levels (control and 120 mM NaCl).
