Accumulation of K+ and Na+ in different parts of rapeseed at seeding stage and bolting stage under saline-alkali stress A: K+ and Na+ contents in leaves, petioles and roots of rapeseed at seeding stage; B: K+ and Na+ contents in leaves, petioles, stems and roots of rapeseed at bolting stage. Treatments and abbreviations are the same as those given in Table 1. Different letters behind the data indicated the significant difference at the 0.05 probability level."
