What does a "germination test" evaluate?

A germination test evaluates the percentage of seeds that will sprout under controlled conditions. This test is key in assessing seed viability, which is essential for farmers and gardeners who rely on quality seeds for successful planting and crop production. By determining the germination rate, growers can make informed decisions about seed selection and planting practices, ensuring that they choose seeds that will yield healthy plants.

The other options focus on aspects that do not assess germination directly. For instance, the weight of the seeds, the quality of the soil, and the age of the seeds are all factors that can influence plant growth, but they do not specifically measure the capability of the seeds to sprout. Thus, option B stands out as the relevant choice for understanding germination testing.
