Responses of Cool Season Grain Legumes to Soil Abiotic Stresses

Response of Some Forage Pea Genotypes to Salt Stress During the Seedling Stage

“…Generally, root growth was less affected by salt stress than shoot growth (Table 1). Similar results were also reported by Jayasundara et al (1998) As salt level increase, seedling fresh and dry weights were decreased especially it was more pronounced after 5 dS m -1 salt content (Table 1). This was mainly orriginated from negative effect of salt stress on plant growth (Parida & Das, 2005).…”

“…The plants are the most sensitive to salt stress during seedling stage and considerable differences occur among genotypes belonging to species are originated from genetical differences (Cerda et al, 1982;Jayasundara et al, 1998;Noreen & Ashraf, 2009). In this study, investigated genotypes showed different response to salt stress with respect to germination percentage and it was decreased at high salt levels.…”

Pretreatment with Antioxidants Decreases the Effects of Salt Stress on Chloroplast Ultrastructure in Rice Leaf Segments (Oryza sativaL.)

“…The effects of salinity in plants have been well investigated on important metabolic processes such as ion uptake and transport, respiration, photosynthesis and the detoxifi cation processes of AOS (Marschner, 1995;Dionisio-Sese and Tobita, 1998;Jayasundara et al, 1998;Meneguzzo et al, 1998), but, few studies have been undertaken on salt-induced ultrastructural changes in cells and organelles. In some studies, salt stress induced changes in chloroplast ultrastructure such as the swelling of thylakoids and the destruction of thylakoid membranes (Hernandez et al, 1995;Rahman et al, 2000;Mitsuya et al, 2003).…”

Root traits of different crops under rainfed conditions in the High Barind Tract of Bangladesh

“…2) and more residual soil moisture. Root distribution and function is greatly affected by soil compaction or high bulk density (Jayasundara et al, 1998).…”
