Cuttings of plants were left out of water in a relatively dry atmosphere. In R. rugosa and R. lutea only flavonosides of the aerial parts were affected: 1 or 2 kaempferol derivatives were reduced, while quercetin levels increased. In R. stylosa, whose limbs contain only quercetin derivatives, flavonic content was not modified by hydric stress.
