Canola Seedling Growth As Affected By Salt Type and Concentration.

High soil salinity adversely affects plant growth and development, including canola. The objective of this research was to determine canola seedling growth under three types of salt (NaCl, Na₂SO₄+MgSO₄, and Na₂SO₄+MgSO₄+CaCO₃) at 2, 4, 8, and 12 dS m^-1. Canola seeds were germinated and grew under the saline conditions for 30 days. Plant height, shoot and root dry weight, and root length decreased with an increasing salinity level. When compared to the control treatment (i.e. non-saline), reduced growth was only observed at 8 dS m^-1 and/or higher. Salt type had no effects on canola seedling growth, except root length in which NaCl resulted lower root length than the other two types of salt.
