seed coat
This term is primarily used in botanical and agricultural contexts to describe the integument of a seed. It carries a neutral, scientific connotation and is used to discuss the biological mechanisms of dormancy and germination.
Because it refers to a specific anatomical structure, it is typically used in technical descriptions of plant biology. In practical gardening or farming, discussions regarding the seed coat often center on scarification, which is the process of physically or chemically breaking this layer to encourage water absorption.
