The sesquiterpene contents in leaves of wild Rosa rugosa and of sixty-one hybrid rugosas were quantitatively measured by a GC analysis. In this group of samples, the greater the number of glandular trichomes the hybrid rugosas possessed on their leaves, the larger the amount of sesquiterpenes they accumulated. In contrast, those having no leaf glandular hairs contained only a trace amount of sesquiterpene components. The concentrations of bisaborosaol A (1) and carota-1,4-dienaldehyde (2) as representative sesquiterpenes of R.rugosa were positively correlated with the density of the glandular trichomes. Furthermore, an approximately regular correlation was observed between the concentrations of 1 and 2 in most of the sesquiterpene-producing hybrid rugosas, regardless of their productivity. This suggests that a major part of these hybrid rugosas have inherited from R. rugosa the ability to produce two skeletally different sesquiterpenes in parallel with a phenotype to develop leaf glandular trichomes. This investigation also led to discovering 1-dominant (e.g., Amelie Gravereaux and Purple Pavement), 2-dominant (e.g., David Thompson), and other-dominant (e.g., Martin Frobisher) types of sesquiterpene-producing hybrid rugosas.
