چکیده مقاله:

In order to study the effects of salinity stress on growth indices of three clover species including, Trifolium resupinatum, T. alexandrinum, and T. incarnatum, an experiment was conducted as factorial based on a completely randomized design arrangement with three replications. Factors included seven levels of salinity stress (0, 41, 82, 123, 164, 205, and 246 mM) and three clover species. Different performance was observed for germination and seedling parameters among the species. In addition, results indicated significant differences among the treatments in all traits and showed that the effects of salinity on all traits were the same at low-stress levels (0 and 41 mM), but differed at higher stress levels. The experimental results revealed that with an increase in salinity level, the greater reduction was observed in vigor index, seedling length, and root and shoot fresh and dry weight while MGT and GU increased. The highest levels of vigor index and root and shoot fresh and dry weight was related to T. resupinatum and T. incarnatum, respectively, while MGT and GU in T. resupinatum were higher than those of the other two species. In addition, T. resupinatum seedling length was higher than the other two species.

Study of Germination and Seedling Growth Parameters of Three Clover Species (Trifolium spp.) under Drought and Salinity Stresses

DOR: 98.1000/2383-1251.1398.6.145.11.1.1575.1610 Extended Abstract Introduction: Agriculture has been influenced by different abiotic stresses such as temperature, drought and salinity, which reduces roughly half of the yield of crops. In many forage plants, germination and early seedling growth are the most sensitive stages of their growth in the face of environmental stresses. Current r...

Mapping Salinity Tolerance during Arabidopsis thaliana Germination and Seedling Growth

To characterize and dissect genetic variation for salinity tolerance, we assessed variation in salinity tolerance during germination and seedling growth for a worldwide sample of Arabidopsis thaliana accessions. By combining QTL mapping, association mapping and expression data, we identified genomic regions involved in salinity response. Among the worldwide sample, we found germination ability ...
