Rugosal and related carotane sesquiterpenes in the glandular
trichome exudate of Rosa rugosa.
The number of adaxial (63) and abaxial (78.75)
trichomes, together with the acylsugar content (35.29 nmols [cm.sup.-2] leaf area) was higher in S.
Fine-scale frequency differentiation along a herbivory gradiente in the
trichome dimorphism of a wild Arabidopsis.
The stem indumentum presents glandular and non-glandular
trichomes (Fig.
Epidermal cell type, type of stomata, type of
trichome, and the nature of the mesophyll have been used before to differentiate P.
Trichome morphology in the genus Cuphea (Lythraceae).
It is known that this species has
trichomes that secrete toxic bimolecular that act on herbivorous insects [53, 64, 36, 14, 62, 37, 23].
The presence of
trichomes can significantly stimulates the retention, and subsequently, the product absorption (Schonherr, 2006).
The diversity in the foliar
trichomes is of taxonomic importance for discrimination of taxa at specific level.
Berlinger (1986) underlines that physical traits of leaf surfaces, such as pilosity, presence of adherent glandular
trichomes and leaf format are aspects affecting oviposition preference by the whitefly.
tabacina disease: the first is the SGT-produced T-phylloplanins and the second is the abundant diterpenes and T-phylloplanins produced by tall
trichomes on older leaves [19].
