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
glaziovii displays rounded transverse section with lateral recess (figure 17), where occur glandular trichomes
(figure 18) with positive reaction to lipid test (figure 18).
Epidermal cell type, type of stomata, type of trichome
, and the nature of the mesophyll have been used before to differentiate P.
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 .
