Sorenson said the results could lead to further improvement or manipulation of glandular trichomes
The number of GTs per unit area was estimated at 20x magnification by counting the trichomes
in randomly selected samples of stems (N = 15) from five juvenile plants (Gravano, Tani, Bennici, & Gucci, 1998).
Furthermore, observations during evaluations indicated that the presence of trichomes
and domatias would result in an important place for these mites to refuge.
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.
The epidermal cells common of the abaxial face resembled that of the adaxial face; however, showing paractic trichomes
and stomata (Figures 1E-H and 1J).
The glandular trichomes
may occur on both faces (Fig.
The anatomical study's with Scabiosa rotata M.Bieb, it is stated that the eglandular trichomes
are present in the stem and leaf, and also a small amount of glandular trichomes
are present in the leaf.
Owing to the presence of trichomes
and sensilla chaetica, we were not always able to view the complete surface of the TAPs, thus our meristic data may slightly under represent the actual number of pores present (Table 1).
The majority of species within Plectranthus genus is succulent leaves and stems and is aromatic due to glandular trichomes
present on its leaves.
Key results: All species contain multicellular uniseriate trichomes
which may be glandular or non-glandular.
It is known that this species has trichomes
that secrete toxic bimolecular that act on herbivorous insects [53, 64, 36, 14, 62, 37, 23].
