Abstract
Seedling growth,ionic absorption and distribution of two rapeseed materials (Brassica napus L.cv Baozayou 1 and B.napus L. line Nanyanyou 11) were studied under 10 days of NaCl (100 and 200 mmol·L-1) stress.The results showed significant inhibition on seedling growth and higher salt tolerance of Nanyanyou 11 under NaCl stresses. Ions of Na+ and Cl-increased markedly and salt-ion content accumulation in shoots was much more than those in roots.NaCl stress led to decrease of K+ and Ca2+ contents. Higher salt tolerance of Nanyanyou 11 was mainly resulted from better ionic homeostasis and higher SK,Na and SCa,Na in roots.
