Variety traits

Freesia Flower Fragrance

Freesia Eckl. ex Klatt

The intensity and profile of freesia fragrance are determined by varietal characteristics and measured using gas chromatography or sensory evaluation. The trait is dynamic and peaks during the full bloom stage.

In the reference 5 varieties crop Freesia, where this is mentioned in the description.

For objective assessment of freesia fragrance, instrumental analysis using gas chromatography-mass spectrometry is employed, allowing for the identification of volatile compound composition, as well as electronic noses for intensity evaluation. In breeding practice, expert sensory evaluation using five- or seven-point scales is also widely used.

Scent intensity is a varietal trait: 'Gold Flame' type cultivars possess high aromaticity, while 'Rose Marie' or 'Blue Heaven' exhibit almost no volatile emission. Modern breeding often prioritizes ornamental characteristics, which can lead to a decrease in fragrance intensity.

Fragrance dynamics depend on environmental conditions and the plant's developmental stage. Maximum emission of volatile compounds occurs during the full bloom stage. Temperature directly influences the evaporation of compounds; therefore, maintaining a temperature of approximately 18°C is critical for preserving the aromatic properties of cut flowers.
