In horticultural terms, what does the term "codominant" refer to?

The term "codominant" in horticulture refers specifically to a situation where two or more independent stems or trunks arise from a single base or point. This often occurs in trees where two leaders grow alongside each other, resulting in a forked structure. This growth pattern can be significant for tree health and stability, as codominant stems can lead to weak branch unions, making them more susceptible to failure during storms or high winds.

In contrast, a single stem growing straight up represents a different growth form, and branch layering techniques pertain to propagation methods rather than structural characteristics of growth. The growth of a plant from seed describes the initial phase of development, which does not relate to the concept of codominance. Understanding these distinctions is crucial for effective tree management and ensuring structural integrity in landscape design.
