“…These results indicated the existence of genetic potential for salt tolerance among this sugar beet O-type lines that could maintain a good growth status in plant aerial part under salt stress and also show that stress intensity (16 dS/m) used in our study, was appropriate which was able to differentiate between susceptible and tolerant controls, and to differentiate genotypes for different traits. This goes in pair with many other studies (Khayamim et al, 2014;Chikha et al, 2016;Abbasi et al, 2018), which illustrate that severe saline stress, could be used as a rapid method to identify visible phenotypic differences among salt tolerant and sensitive genotypes.…”

“…The second group consisting of seven genotypes were dedicated to moderately tolerant to salinity and the remaining eight O-type lines with low amount of weight related traits, were classified as sensitive to salinity. In many researches, Ward's clustering technique based on STI values was able to distinguish genotypes with contrasting demeanor toward salinity (tolerant/sensitive) (Win et al, 2011;Mini et al, 2015;Kim et al, 2016;Sakina et al, 2016;Abbasi et al,2018). .…”

Increased production of sugar beet under rainfed conditions on saline-sodic soils in the Iranian areas highlights the importance of salt tolerant varieties. Screening of genotypes for salinity tolerance is difficult in field due to heterogeneity of physical and chemical properties of soil. In order to evaluate the salinity tolerance of 21 sugar beet monogerm O-types lines, a pot experiment was conducted using a split plot design. The evaluation of plants was performed using 11 morphological and physiological traits at vegetative growth stage under severe salt stress (∼16 dS m-1) and control (0.3 dS m-1) for 8 weeks. Salinity stress significantly reduced weight related traits. The response of genotypes for total weights and stem weights was very similar under both conditions. But, ranking of O-type lines for root weights under normal and stress condition was different. Indeed, there was high significant genotype × treat interaction for two these traits. Cluster analysis by using STI index of all traits allowed the identification of tolerant, moderate tolerant and sensitive genotypes toward salinity. The four salttolerant genotypes, O-type 9669, O-type 1609, O-type 463-2, and O-type 463-5 identified in this study, could be used in the development of salt-tolerant sugar beet varieties. In the second part of this study in order to assess a simple, rapid, and nondestructive method to estimate chlorophyll content, the chlorophyll meter (SPAD 502) readings were recorded and the relation was determined. Regression analysis indicated that there was a significant linear regression between chlorophyll content and chlorophyll meter and about 74% of changes in chlorophyll meter based on chlorophyll content were predicted.

“…Starch is found exclusively in the perisperm, while proteins and lipids are in the embryo (Prego et al, 1998). The same structure can be observed in the sugar beet (Abbasi et al, 2018) and amaranth seeds (Ye and Wen, 2017). The high protein content of quinoa is due to the fact that 60% of the seed weight corresponds to the embryo that has a hypocotyl-radicle axis and two cotyledons.…”

Seed quality of 22 quinoa materials (Chenopodium quinoa Willd.) from the department of Boyacá 1 Chenopodium quinoa Willd. is a pseudocereal with seeds that are a rich source of vitamins and minerals. However, there are few studies on quinoa seed quality, especially for the Colombian germplasm. So, the objective of this research was to determine the quality of 22 quinoa materials from the Department of Boyacá by evaluating the physical (color, shape and diameter) and physiological (tetrazolium test) quality of the seeds. It was found that 36% of the materials had a white grain color, 80% cylindrical shape, 65% smooth edges and diameters smaller than 2mm, desirable characteristics for post-harvest processes. The evaluated physical characteristics presented high variability between the evaluated materials, which is desirable for elite breeding processes. The imbibition rate showed that germination was rapid (at 4 hours, the weight of the seeds doubled), that is, the materials were not dormant. Finally, it was determined that storage conditions, such as temperature and relative humidity, are essential for preventing deterioration in quinoa seeds; these factors can also affect germination and long-term vigor.

“…High soil salinity causes adverse effects on different plant responses in terms of morpho-physiology and biochemistry, leading to a severe reduction in crop productivities [10,11]. Soil solutions containing Na + and Cl − ions due to high salinity cause osmotic stress, ionic imbalance, nutrient uptake antagonism (especially Na + with K + ), and damage to cellular membranes and some organelles by producing reactive oxygen species (ROS) [12][13][14]. Salinity also disrupts the synthesis of proteins, metabolic enzymes, particularly nitrate reductase [15], and other important cellular macromolecules, thus, it severely impairs photosynthesis and plant growth, resulting in a loss of about 20-50% of crop yields [11].…”

“…Sugar beet salt resistance reaches EC e = 7 dS m −1 as a critical maximum without a decrease in its economic yield [16,17], which depends on the stage of plant growth and/or the state of salt tolerance of the cultivated genotype [18]. Although high Na + ion concentrations have detrimental effects on the growth and survival of some plants [13][14][15], a low Na + concentration may be required for normal sugar beet growth and may replace K + in some nonspecific metabolic activities under K + deficiency [19,20].…”

Integrated Application of K and Zn as an Avenue to Promote Sugar Beet Yield, Industrial Sugar Quality, and K-Use Efficiency in a Salty Semi-Arid Agro-Ecosystem

Salinity combined with a deficiency of potassium (K) and zinc (Zn) negatively affect sugar beet yield and quality. A two-year (2017/18–2018/19) field trial was undertaken to investigate the mediating role of soil-applied K [120 (K120) and 180 (K180) kg ha−1] and foliar-applied Zn [0 (Zn0), 150 (Zn150), and 300 (Zn300) ppm] in alleviating salt-stress (8.60 dS m−1) based on sugar beet morpho-physiological responses, sugar yield and quality, and K-use efficiency in the BTS 301 and Kawemira cultivars. Application of K180 × Zn300 was more effective and resulted in 23.39 and 37.78% higher root yield (RY) and pure sugar yield (PSY), respectively, compared to control (K120 × Zn0). It also enhanced sucrose, pure sugar (PS), and purity but decreased impurities (α-amino N, K, and Na), alkalinity index, and sugar loss. However, the K120 × Zn300 recorded higher K-use efficiency. PSY correlated positively (r = 0.776 **, 0.629 **, 0.602 **, 0.549 **, and 0.513 **) with RY, root fresh weight (RFW), top yield, PS, and root diameter, respectively. The stepwise and path-coefficient analysis demonstrated that RY, PS, and RFW were the most influential PSY-affected attributes. Integration of K180 + Zn300 can correct K and Zn deficiencies in the soil and mitigate salt-stress effects via improving sugar beet growth, yield and quality, and K-use efficiency.
