“…Here 0 means no damage; 1 means very slight damage; 2 means 25–50% of leaves yellow; 3 means 50–75% of leaves yellow; 4 means more than 75% of leaves yellow and 5 means all seedlings dead. The Na + and K + in shoots and roots of each sample were extracted using 6.5 mL nitrification liquid [32] including 60% trichloroacetic acid (1 mL), 98% nitric acid (5 mL) and 98% sulfuric acid (0.5 mL), and the concentrations in roots (RNC and RKC) and shoots (SNC and SKC) were analyzed by atomic absorption spectroscopy using a TAS-986 machine (PGENERAL, Beijing, China).…”

The key to plant survival under NaCl salt stress is maintaining a low Na+ level or Na+/K+ ratio in the cells. A population of recombinant inbred lines (RILs, F2∶9) derived from a cross between the salt-tolerant japonica rice variety Jiucaiqing and the salt-sensitive indica variety IR26, was used to determine Na+ and K+ concentrations in the roots and shoots under three different NaCl stress conditions (0, 100 and 120 mM NaCl). A total of nine additive QTLs were identified by QTL Cartographer program using single-environment phenotypic values, whereas eight additive QTLs were identified by QTL IciMapping program. Among these additive QTLs, five were identified by both programs. Epistatic QTLs and QTL-by-environment interactions were detected by QTLNetwork program in the joint analyses of multi-environment phenotypic values, and one additive QTL and nine epistatic QTLs were identified. There were three epistatic QTLs identified for Na+ in roots (RNC), three additive QTLs and two epistatic QTLs identified for Na+ in shoots (SNC), four additive QTLs identified for K+ in roots (RKC), four additive QTLs and three epistatic QTLs identified for K+ in shoots (SKC) and one additive QTL and one epistatic QTL for salt tolerance rating (STR). The phenotypic variation explained by each additive, epistatic QTL and QTL×environment interaction ranged from 8.5 to 18.9%, 0.5 to 5.3% and 0.7 to 7.5%, respectively. By comparing the chromosomal positions of these additive QTLs with those previously identified, five additive QTLs, qSNC9, qSKC1, qSKC9, qRKC4 and qSTR7, might represent novel salt tolerance loci. The identification of salt tolerance in selected RILs showed that a major QTL qSNC11 played a significant role in rice salt tolerance, and could be used to improve salt tolerance of commercial rice varieties with marker-assisted selection (MAS) approach.

“…Determination of Na þ and K þ Na þ and K þ in plant species were extracted for 5 min with trichloroacetic acid, HNO 3 and H 2 SO 4 at 901C in a water bath following the method of Gulati & Jaiwal (1992). Soluble Na þ and K þ in soils were extracted by soaking in deionized water (water/soi1, 5/1).…”

The objective of this study was to identify morphological and physiological traits for salinity tolerance in Tunisian autochthonous ZZ pearl millet ecotype (Pennisetum glaucum (L.) R. Br) under local conditions. ZZ ecotype was cultivated under different levels of salinity and growth parameters, water relations and mineral content were measured. Results showed that ZZ pearl millet ecotype was unable to store the large amounts of salt in the leaves, while maintaining high leaf water content and without a grave consequent on panicle yield. This ecotype is fitted for a selective sodium sequestration in the vacuole.
