What is the tillering stage in plant growth?

The tillering stage in plant growth refers specifically to the formation of erect shoots, known as tillers, that emerge from the base or crown of the plant. This stage is crucial for many grass species and some cereal crops, as it significantly impacts the overall yield. During tillering, the plant begins to develop additional stems that will eventually support seed head formation, increasing the number of productive tillers that can contribute to grain production.

This stage occurs after the vegetative growth phase, where the plant focuses on expanding its leaf area. By producing multiple tillers, the plant can optimize resource use, capture more sunlight, and promote photosynthesis, ultimately leading to a more productive structure. Understanding this growth stage is essential for effective crop management and herbicide application, as the requirements and sensitivities of the plant can change significantly as it progresses through its growth stages.
