Impact of Salt on Seed Germination
Introduction
Germination is a key event in a plant’s lifetime and controlled by two main factors which are water and salt stress (Yuan et al., 2016 and Vallejo et al., 2010). Salt stress affects plant growth and crop production by causing osmotic and ionic stress in plants. Alonso-Blanco et al in 2009 reported that less study was made on the traits in Arabidopsis thaliana despite the immense genetic variation present in the species and the importance of seed adaptation to salt and drought stress. Many studies on the molecular basis of salt tolerance in Arabidopsis thaliana had been done, however, the genetic variation that causes salt tolerance and other abiotic stresses in the species had not been widely …show more content…
The line chart in Figure 2 also shows that the mean germination between different genotypes is different with genotype Moa-0 showing the highest mean germination and genotype Lov-5 as the lowest and Lesno-4 showing no germination at all. Furthermore, it is shown that all the seeds failed to germinate at 0.2M and 0.3. Figure 3 Bars represent standard error measurement Figure 4 Bar chart of mean germination against salt concentration
The bar chart in Figure 4 compares the seed germination in different genotype where the genotypes Sha and Moa-0 shows the higher mean of seed germination in 0.1M than the other three genotypes that germinated. The result obtained from Kruskal-Wallis test is there were significant effects of salt concentration (Kruskal-Wallis chi-squared = 257.48, df = 3, p-value < 0.001) and variability of genotypes (Kruskal-Wallis chi-squared = 70.551, df = 5, p-value < 0.001) on the seed
