Physiological changes in Mimosa caesalpiniifolia Benth. seeds from different sources and submitted to abiotic stresses

Abstract: A B S T R A C TSeed germination of species that develop in arid and semi-arid soils can be altered by water deficit and abundance of salts in the soil. Knowledge on tolerance limits is fundamental to understand the adaptive capacity of species under such conditions. The objective of this study was to evaluate the physiological changes (germination and vigor) of Mimosa caesalpiniifolia seeds from different regions and submitted to water and saline stresses. To simulate water stress, the osmotic agent polyethyle… Show more

“…Nasr et al, (2012), pointed out that saline stress during germination affects cell division and elongation, and therefore, mobilization of essential reserves for this stage. Furthermore, under saline stress, seed reserves that could be used for growing embryonic axis are used to repair damaged cells (45). Saline stress increases MGT and reduces germination percentages, as shown by this study.…”
