where this is mentioned in the description.
Official apple variety testing protocols lack units of measurement or scoring scales for evaluating blossom fragrance. Descriptions of this trait in literature are subjective and qualitative in nature and lack quantitative metrics.
Fundamental biochemical research studies the composition of volatile organic compounds, such as linalool and benzyl acetate, but these data are not included in agronomic regulations. The practical significance of fragrance is primarily limited to ornamental gardening as a criterion for aesthetic evaluation or to pollination biology for attracting insects.
