The process of seed germination is considered a critical phase of development in the life cycle of plants and is important for the establishment of seedlings, in addition to being directly related to the ability to adapt to severe environmental conditions. One way to maintain seed quality is through the application of chemical treatments, usually with fungicides, inoculants, stimulants, micronutrients and others. However, the indiscriminate use of agrochemicals means that there is a need for alternative products, preferably biodegradable and that do not present toxicity to humans and animals. In this sense, turmeric, which has several pharmacological activities, such as anti-inflammatory, antimicrobial, antimutagenic and antioxidant effects, due to the presence of the metabolites such as curcumin, may represent benefits in seed treatment and in the initial development of seedlings.
