Branches of plants such as grasses that occur below or near the ground. Produced on relatively large and nutrient-rich tiller nodes. The first-order tiller is called directly from the tiller node at the base of the main stem, and new tiller buds and adventitious roots can be produced at the base of the first-order tiller to form the second-order tiller. Under good conditions, the third and fourth stage tillers can be formed. As a result, a plant forms many branches that are clustered together. Tillers born in the early stage that can head and bear fruit are called effective tillers, and those born in the late stage are called invalid tillers. Effective tillering is directly related to the number of ears per unit area.
For example, the tiller number of wheat is affected by various conditions such as water, fertilizer, light, temperature, and agricultural measures. If the conditions are right, there will be more tillers. In theory, tillers are infinite. Some people use a single wheat seed to grow hundreds of tillers and extract more than 100 ears of wheat.
