Abstract:

For studying the effects of seed priming with ethanol, methanol, Zn, B and Mn on seed mineral concentration at 8 weeks after planting and the end of growth in Canola (Brassica napus L.), 2 separate laboratory and greenhouse experiments were conducted. Laboratory experiment was performed as a Completely Randomized Design with 6 priming treatments: (Non-primed, 2% ethanol, 2% methanol and 0.5% each ZnSo4, H3BO3, and MnSO4.H2O solutions) in three replicates. Greenhouse experiment was conducted as a factorial experiment form by Completely Randomized Design with 4 levels of irrigation: (100%, 75%, 50%, and 25% FC) with 3 replications. The detailed results of the study proved that Zn, B, and Mn application through canola seed treatments could be used to increase this mineral concentration in seeds under normal irrigation (100% FC) at 8 weeks after planting and the end of growth compared with the other treatments. Based on the results, the Zn concentration showed an increase of 79% (8WAP) and 40% (EOG), due to Zn-seed priming. Also, the B concentration showed an increase of 2/5 times (8WAP) and 2/2 times (EOG), due to B-seed priming and Mn- seed priming increased 2/5 times (8WAP) and 93% (EOG) Mn concentration of the seeds.
