Description

At the laboratory

At the LBVpam, the Rose has been studied for 25 years from various angles ↓

Its biochemical interest

The Rose's biosynthetic pathways are highly original. Although it produces the same products as many of its congeners, the Rose uses completely different mechanisms to achieve the same result. This difference is of interest in understanding adaptation mechanisms in plants.

 

Its cultural interest

The rose has fascinated humankind since the dawn of time. It has appeared in the arts, its trade has contributed to the economic boom in the Mediterranean and today it remains the ‘Queen of Flowers’.

 

Its economic interest

Rose research began in association with rose growers. Cut flower research was also innovative. Understanding the flower means that it can be cultivated to ever higher quality.

Rose quiz

Do all roses smell more or less the same?

No. Not all roses emit the same volatile compounds, or the same quantities, or from the same organs.

"Thus, for example, R. rubiginosa has a strong apple scent on its leaves, R. bracteata has a lemony scent close to that of pineapple, R. foetida a floral scent of true bug, R. arvensis of myrrh, R. moschata of musk and clove on its petals and stamens’ and R.roxburghii has no scent."

Extract from "Parfum des Roses", Jean-Claude Caissard and Sylvie Baudino

How are roses distilled?

The roses are picked by hand in the morning, when they are most fragrant, and are distilled directly. This is done using the hydrodistillation technique.

To produce 1kg of essential oil, you need to distil 3 to 5 tonnes of roses, or around 200 million petals. The price of rose essential oil is therefore very high.

This is why perfumers substitute rose essential oil with that of Geranium Rosat, which is less expensive.

Which fragrant molecule has a typical rose scent?

Geraniol
