“…The GP of Hisar Unnat okra is 66.3% [ 39 ]. Under seed priming conditions, the GPs of six okra accessions were 25.33–88.00% [ 40 ]. In this study, the 180 okra accessions had a GP of 80.41% on day 7 under the CK condition, while the GP on day 3 was only 70.81%.…”

“…Further statistical analysis of these SNPs revealed that 167 were detected by both programs simultaneously, and they are relatively stable SNP loci (Table S5). These 167 SNPs were located on 21 of the 65 okra chromosomes, namely, chromosomes 4,5,15,17,19,22,24,25,31,37,40,41,43,44,45,46,54,56,59, 61, and 64. Among them, chromosome 31 had the most marker-trait associations (66) detected.…”

Excessive soil salinity is a major stressor inhibiting crops’ growth, development, and yield. Seed germination is a critical stage of crop growth and development, as well as one of the most salt-sensitive stages. Salt stress has a significant inhibitory effect on seed germination. Okra is a nutritious vegetable, but its seed germination percentage (GP) is low, whether under salt stress conditions or suitable conditions. In this study, we used 180 okra accessions and conducted a genome-wide association study (GWAS) on the germination percentage using 20,133,859 single nucleotide polymorphic (SNP) markers under 0 (CK, diluted water), 70 (treatment 1, T1), and 140 mmol/L (treatment 2, T2) NaCl conditions. Using the mixed linear model (MLM) in Efficient Mixed-model Association eXpedated (EMMAX) and Genome-wide Efficient Mixed Model Association (GEMMA) software, 511 SNP loci were significantly associated during germination, of which 167 SNP loci were detected simultaneously by both programs. Among the 167 SNPs, SNP2619493 on chromosome 59 and SNP2692266 on chromosome 44 were detected simultaneously under the CK, T1, and T2 conditions, and were key SNP loci regulating the GP of okra seeds. Linkage disequilibrium block analysis revealed that nsSNP2626294 (C/T) in Ae59G004900 was near SNP2619493, and the amino acid changes caused by nsSNP2626294 led to an increase in the phenotypic values in some okra accessions. There was an nsSNP2688406 (A/G) in Ae44G005470 near SNP2692266, and the amino acid change caused by nsSNP2688406 led to a decrease in phenotypic values in some okra accessions. These results indicate that Ae59G004900 and Ae44G005470 regulate the GP of okra seeds under salt and no-salt stresses. The gene expression analysis further demonstrated these results. The SNP markers and genes that were identified in this study will provide reference for further research on the GP of okra, as well as new genetic markers and candidate genes for cultivating new okra varieties with high GPs under salt and no-salt stress conditions.

“…Seed germination is the process by which a dormant seed becomes a healthy seedling (Chen et al, 2021). The process of radicle formation involves several steps, including water absorption, molecular breakdown, genetic material repair, endosperm and embryo elongation, and seed coat disintegration (Rima, 2021;Rhaman et al, 2020). Successful germination is crucial for both the final product and the early-stage development of seedlings (Khanal et al, 2022;Kharat and Pottathil, 2021).…”

The present study has been conducted to study the effect of various primer treatments i.e., PEG (5%), PEG (10%), NaCl (2%), KCl (2%), CuSO4•5H2O (2%), NaOH (2%) and control on germination and growth of two okra (Abelmoschus esculentus) varieties (var. Arka Anamika and Clemson). Growth parameters were measured at 10, 20, and 30 DAS, while germination parameters were recorded over a period of seven days. Compared to Arka Anamika, Clemson showed better germination and growth metrics, which also showed significant differences in seed priming treatments. The use of different concentrations of PEG solution for seed priming proved to be particularly effective as evidenced by the highest germination percentage (79%), speed (95.95%), energy (76%), and Vigor index (2037.94 cm). Growth parameters also showed significant differences with these treatments. Similarly, seed priming with 2% NaOH and 2% CuSO4•5H2O had the lowest results for growth and germination metrics. The results highlight how priming can significantly improve the germination and growth of okra seedlings; the Clemson and PEG solution treatments stand out as particularly successful techniques. This highlights the potential for improved okra production through the use of these priming methods.
