Comparative Study for Seed Germination and Seedling Initial Growth under Elevated NaCl Concentrations to Four Species of the Brassica Genus
Year: 2016
Type: article
Abstract: One of the most challenges that encounter humans’ nutrition is the salinity increases in soil and water which leads to highly limitation in crops production. Furthermore the ability of seeds to germinate at high salt concentration in the soil is critical importance for the survival, propagation and production of many plant species. Seed germination and seedling growth of four species belong to the genus Brassica (B. alba, B. niger, B. juncea and B. napus) were evaluated under conditions of salinity (control, 150, 200, 250 and 300ml M).The obtained results showed that seeds of all the species germinate at all concentrations of NaCl. Percentage of viable seed germination for all tested species show slightly closely results only at the highest concentration (300 mlM) B. napus show significant higher seeds germination percentage than the other three species. However, root length of all the examined species slightly similar at lowest concentration while starting with concentration 200 ml MB. napus shows significant increase in root length than the other three tested species. B. napus shows more stability to the salinity condition than the other three species.
