Seed aging is a phenomenon that causes a lot of economic losses every year and therefore it is necessary to use new and efficient methods to deal with this problem. Vitamins in B group play a defensive and antioxidant role and they are effective in growth and development, so it is possible that they can heal the effects of seed aging. For this purpose, an experiment was conducted at Shahrood University of Technology in March 2017 to investigate the effect of seed pretreatment with B group vitamins on the growth and yield of canola in seed deterioration conditions. The experiment was factorial based on randomized complete block design with 3 replications. Experimental treatments included 3 levels of seed deterioration (0, 50 and 100 hours) and 7 levels of seed pretreatment with B vitamins (No pretreatment, Distilled water, thiamine, Riboflavin, Niacin, Pantothenic acid and Pyridoxine) with a concentration of 100 mg/l. Seed deterioration was done at 40C and seed pretreatment for 8 hours. The results showed that all the measured traits decreased by seed deterioration and only the amount of anthocyanins increased. In severe deterioration, seed pretreatment with distilled water and pyridoxine increased protein as well as oil yield respectively. Pantothenic acid pretreatment increased the amount of anthocyanins, total chlorophyll and grain yield at severe deterioration levels. This treatment increased grain yield by 143 percent compared with the plants grown from seeds without pretreatment. In general, among the treatment investigated in this study, the pretreatment of seeds with pantothenic acid and thiamine improved and increased many traits such as seed yield, oil and protein content. The advantage of these treatments was quite obvious in normal seeds but in aged seeds there was no significant difference with distilled water. Therefore, the results showed that in aged seeds, a similar result can be achieved by using distilled water with less cost.
