Introduction: Seed germination is a process in which the resting seed imbibes water, the seed radical elongates and passes through the seed coat surrounding the embryo. However, most plant seeds do not germinate immediately and undergo a period of dormancy. These dormant seeds are normally dehydrated, contain inactive enzymes and are resistant to adverse conditions. These characteristics allowed seeds to be dispersed before germination and survive adverse environmental conditions such as drought. For a seed to break dormancy, optimal conditions were necessary for the seed to germinate. There are three important conditions for seeds to germinate: suitable temperature, sufficient water supply and also a satisfactory oxygen level. Water supply is important because it is used to rehydrate seed tissues and cause breakdown of the seed coat which provides a physical barrier for radical elongation (Debeaujon et al., 2000). In addition, oxygen is also an essential element for seed germination, because aerobic respiration of seed tissues produces energy, ATP, necessary for further development of the embryo. The optimal temperature for potential seed germination varies among plant species, but it is one of the important factors that affect seed germination. Factors such as light and hormones also contribute to the seed germination process. Exposure to light is essential for the germination of certain plant seeds. Additionally, light has an indirect effect on ambient temperature. Hormones are important because they signal the production of enzymes in seeds to carry out processes such as mitotic division, cell wall breakdown, and cell differentiation. So, the purpose of this experiment is to study the effect of light, planting depth and hormones on seeds. germination.Materials and methods:In section A, the effect of light on seed germination was studied. The materials used in section A were 100 lettuce seeds, 100 green beans, 4 petri dishes, cotton and 4 filter papers. 2 Petri dishes were labeled water + light (LS) and water + dark (LS). The other 2 Petri dishes were labeled water + light (GB) and water + dark (GB). All Petri dishes were placed with filter paper moistened with 2 ml of water. Then, 5 ml of water is used to moisten the cotton wool that has been placed on all the Petri dishes. 50 lettuce seeds were placed in each Petri dish labeled LS and 50 green beans were placed in each Petri dish labeled GB..
