Abstract
The effects of salicylic acid (0.00, 15 and 30 mu M) on the concentrations of saturated fatty acids (palmitic and stearic acids) and unsaturated fatty acids (oleic, linoleic and linolenic acids) of 12 month stored moistened canola seeds (7, 10, 13 and 16%) was evaluated. The salicylic acid application significantly decreased the saturated fatty acids and increased the unsaturated fatty acids concentrations especially under the high seed moisture contents. Palmitic and stearic acids concentrations decreased by around 40% using 15 or 30 mu M salicylic acid compared with 0.00 mu M salicylic acid in the most moistened seeds (16%). Application seeds (16% moisture) with 15 mu M salicylic acid significantly increased oleic, linoleic and linolenic acid concentrations to 61.42, 17.03 and 8.72% compared with 56.66, 10.55 and 4.86%, respectively, under 0.00 mu M salicylic acid. The 15 mu M salicylic acid was the best treatment to improve oil quality of the high moisture stored canola seeds.
