Abstract :

Canola with the scientific name Brassica napus L., due to its high oil content in the seed, produces one third of all edible oils worldwide, which plays an important role in improving the nutritional needs of societies. Accelerated aging test is one of the most important tests used to evaluate the viability and physiological potential of seeds. Unsuitable environmental conditions as well as seed storage conditions can cause oxidative stress in seeds and other plant tissues. In this study, the improvement effect of pretreatment of vitamin C and Hydroquinone on canola seed under accelerated aging and the developmental and phytochemical characteristics of seedlings obtained from aged canola seed including morphological traits, germination indices and phytochemical changes were investigated. Pre-treatment of seeds with antioxidant compounds reduced the damage caused by decay, improved the quality of canola seeds and seedlings, and also changed the phytochemical composition of the seedlings. The reduction of seed germination and weak morphometric characteristics of seedlings obtained from old seeds indicate the relationship between the phytochemical changes of seeds and the aging process. Seedlings obtained from old seeds showed phytochemical changes in the metabolic pathways of carbohydrates and proteins. If the aging process of the seed does not lead to death of seed, the resulting seedlings will have a different destiny with high power to deal with oxidative stress. It seems that the seedlings receive the signal from the free radicals of seed aging and cause the growth of intelligent seedlings to deal with the stress.
