Ng day and 22 C at evening with relative humidity of 650 . The seeds were surface sterilized with 5 sodium hypochlorite option for 30 min and rinsed with distilled water many occasions. Sterilized seeds had been placed on germination paper in Petri dishes and incubated for 72 h. Sterile plastic containers with styrofoam sheets had been utilised for screening the genotypes under hydroponics. Styrofoam with 10 16 matrix of hole was utilized, exactly where the bottom in the hole was covered by stitching nylon net to prevent seeds from falling into the nutrient remedy. The plastic tray was filled with 15 liters of modified Yoshida nutrient remedy [84] and styrofoam sheet was allowed to float around the remedy. The components and concentrations of modified Yoshida nutrient resolution are presented in Supplementary Table S3. A single wholesome pre-germinated seed was placed in every single hole of styrofoam sheet with each and every genotype inside a row (ten holes). Every single plastic tray could accommodate 14 test genotypes in addition to sensitive (IR29) and tolerant (FL478) checks. The whole experimental set up consisted of plastic trays with modified Yoshida nutrient solution in entirely randomized design (CRD) with two replications and every genotype comprised of ten plants per replication. Fourteen days soon after germination, saline solution with 60 milimolar (mM) NaCl (EC of six.9 dS/m) was added to the tray and following 3 days, salinity anxiety was raised to 120 mM (EC of 13.9 dS/m) which was maintained till final DNMT1 custom synthesis phenotypic scoring. The container was refilled with fresh nutrient remedy keeping the essential salinity level and pH of 5.0 at each and every four days interval. On 16th day after first salinization, the genotypes were visually scored making use of modified common Kinesin-14 Purity & Documentation Evaluation system for rice [85]. 4.3. Measurement of Morpho-Physiological Characters Right after final scoring, three plants per genotype have been rinsed three occasions in distilled water and information on seven traits viz., SL, SFW, RL, RFW, SEW, SDW, and RDW had been recorded. For each plant, the SL was recorded from the base on the plant for the tip of your longest leaf when RL was measured in the base on the plant towards the tip on the longest root. Plants were dried in hot air oven at 80 C for 72 h and SDW and RDW had been measured making use of a higher precision digital balance. Dried samples of shoot and root have been made use of for assessment of Na+ and K+ ion concentration. four.4. Estimation of Na+ and K+ Ion Concentration The Na+ and K+ ion content in the root and shoot samples were determined working with flame photometer as described by Yoshida et al. [84]. The oven dried plant material was ground to fine powder. About one hundred mg of the ground powder was added into a test tube containing 15 mL of di-acid digestion mixture (HNO3 and HClO4 , ten:three). The mixture was cooled and transferred to a 50 mL volumetric flask and volume was made up to 50 mL employing double distilled water. The mixture was shaken gently and filtered with Whatman numberPlants 2021, ten,13 of42 filter paper and concentration of Na+ and K+ ions was estimated employing Systronics Kind 128 Flame Photometer (Systronics Gujarat, Ahmedabad, India). 3 replicates were performed per sample and also the typical value with the replicate was taken. The concentration of ions was expressed in millimoles per gram of dry weight (mmol/g of dry wt). four.five. Data Evaluation Descriptive statistics and correlations involving traits have been worked out using R v.3.6.0. Hierarchical cluster evaluation [86] was performed utilizing Ward’s method [87] and clusters had been ge.
