The present research examined the mechanisms of salt tolerance in five different quinoa genotypes at four different salinity levels (control (60), 80, 120, and 160 mM NaCl). ISSR and SCoT analysis revealed high polymorphism percentages of 90.91% and 85.26%, respectively. Furthermore, ISSR 1 and SCoT 7 attained the greatest number of polymorphic amplicons (27 and 26), respectively. Notably, LINE-6 and M-28 genotypes demonstrated the greatest number of unique positive and negative amplicons (50 and 42) generated from ISSR and SCoT, respectively. Protein pattern analysis detected 11 bands with a polymorphism percentage 27.27% among the quinoa genotypes, with three unique bands distinguishable for the M-28 genotype. Similarity correlation indicated that the highest similarity was between S-10 and Regeolone-3 (0.657), while the lowest similarity was between M-28 and L...

Two open-field experiments were conducted during 2015/2016 and 2016/2017 seasons at the Experimental Farm, Faculty of Environ. Agric. Sciences, Arish University (31° 08' 04.3" N, 33° 49' 37.2" E). This work was aimed to evaluate the performance of four bread wheat (Triticum aestivum L.) cultivars i.e.; Misr-1, Sakha-93, Giza-168 and Gemmeiza-9) in relation to two irrigation pattern i.e. surface supplemental irrigations (12 irrigations) and rainfed under the metrological conditions of North Sinai. Results obtained from experimental field studies were used as indicators to test the performance of DSSAT-CSM (Cropping System Model) Ver. 4.5.1.023. Necessary files were prepared as required. Two different climate scenarios have been implemented in order to study effects of future climate changes on wheat plant growth and yield. Scenarios were done by adding 2°C and 4°C to maximum and minimum temperatures of the last successful winter season (2016/2017) starting from the best sowing date indicated at conducted field experiments and finishing by the end of growing cycle. The future impacts of climate change on wheat showed that increasing in temperature will reduce length of growing cycle and the time needed to full tillering in addition to the final yield. This subsequently will reduce the amount of grain yield; accelerate time for maturity and harvesting. For +2°C scenario, reduction in grain yield, as predicted by the model, will be reach 9.6% loses in grain yield for supplementary irrigated Gemmeiza-9 cultivar and averaged of 18% among all other cultivars. Scenario of +4°C will reduce supplementary irrigated Gemmeiza-9 grain yield by 16.2% and within an average of 23.8% among all other cultivars. The reduction will be more under rainfed irrigation pattern. Generally, Supplementary irrigated Gemmeiza-9 cultivar is recommended treatment to maximized bread wheat grain yield and as an adaption measure to reduce yield variability as affected by increasing of potential temperature scenarios under North Sinai environmental conditions and all similarity regions.

Sea water is available water resources and renewable and non-exploited, it is necessary to maximize use of this water through scientific research for use in irrigation of wheat, to increase the cultivated area and thus, increase production towards self-sufficiency. So, two field experiments were carried out at Faculty of Environmental Agricultural Sciences, EI-Arish, Suez Canal University, during 2012/2013 and 2013/2014 seasons aiming to investigate the response of three wheat cultivar (Triticum aestivum. L.; Masr 1 , Masr 2, Sakha 93) to four mixing ratios between well-water and sea water (control, 3:1, 2:1 and 1:1). Plants were subjected to salinity treatments at 60 days after sowing (DAS). Results showed that Masr 2 and Masr 1 cvs were superior for yield and its attributes, the superiority was obtained from Masr 2 cv as well as seed content of proline and protein. Also, dry leaf content of Na + and Cl-2 were higher for Masr 2 as compared to the other studied cultivars under low mixing ratio (3:1 Well water: Sea water), while, the K + concentration was decreased with the same treatment of Masr 2. For soil analysis, EC, Na + , Mg +2 , K + , HCO 3-2 and Clincreased but Ca-2 decreased under the highest mixing ratio (1 Well water: 1 Sea water). So, it could be recommended to cultivate Masr 2 wheat cultivar under North Sinai conditions, using mixing ratio 3 Well water : 1 Sea water to maximize the benefit of sea water and gain economic productivity of bread wheat in this area and similar regions.

Climate modification causes a considerable influence on the production of several secondary metabolites of plants. In the present investigation, the effect of environmental factors on genetic divergence for three varieties of Stevia rebaudiana (Spanti; China and Eg1) by using differential response for different climate modification (black net, white net and plastic cover in comparing to without cover treatment (control) was studied. Data indicated that the application of different modification treatments showed that the use of nets had significant effect on air and substrate temperature and light intensity as well as relative humidity. In the same context, vegetative growth traits and biochemical analyses for stevioside and rebaudioside content had significant effects according to climate modification treatments. Electrophoresis banding patterns of total protein and isozyme (peroxidase) were obtained to characterize genetic relationship for both different treatments and genotypes. Based on the resolved soluble protein profiles it could be detected 11 and 13 polymorphic unique bands for different treatments and genotypes, respectively. The percentage of polymorphism for all studied treatment and varieties was 100 %. 12 and 13 polymorphic bands were detected in Isozyme marker (peroxidase) analysis for different treatments and genotypes, respectively. However, black net treatment and Spanti variety has the highest polymorphism percentage 100% by using cluster analysis of banding pattern for examined treatments and genotypes based on similarity index and UPGMA resulted four distinct clusters.

This study has been carried out at the Faculty of Environmental Agricultural Science, Arish University, Egypt during the two successive growing seasons 2016/2017 and 2017/2018. The experiment has been done at the shad net house of the experimental crop farm using quinoa seedlings (one month old), which grow in pots. Seedlings have been irrigated every two days using four treatments of irrigation water (control, 100, 150, 200 mM), where control was tap water 85 mM. It was observed that vegetative parameters of quinoa seedling were significantly decreased with increasing water salinity concentration .The highest value for each of plant height, root length, number of leaves, leaf dry weight, shoot dry weight, root dry weight, water relative content was obtained with low saline control, followed by 100, 150 and 200mM which gave the lowest values in this respect. Concerning growth analysis, the maximum value for each of leaf area duration, relative growth rate, crop growth rate and net assimilation rate was achieved by control, followed by the other respected studied concentration which gave the lowest values. The obtained results cleared that the concentration of nitrogen, phosphorus and potassium, pigments decreased in plant tissue with increasing water salinity concentration. However, sodium and proline concentrations increased in plant tissue with increasing salinity concentration. It worthy to note that there were significant differences between Giza1 and Giza2 in most studied parameters.
