“…The features of the stoma and cuticle structure observed were those generally used in descriptions of Finns subgenus Pinus (Trautmann, 1953;Mirov, 1967;Esau, 1982;Yoshie and Sakai, 1985; .<f fi .r e. Hansen, 1995;Farjon and Styles, 1997;Sweeney, 2003). The present study, however, identified significant differences among some of these variables that allow P. sylvestris and P. uncinata to be distinguished.…”

“…Later studies have emphasized the taxonomic importance of this ring. Six different types have been identified; four of them occur in the subgenus Pinus, of which one is seen in P. sylvestris (Yoshie and Sakai, 1985;Farjon and Styles, 1997;Kim et al, 1999;Whang et al, 2001Whang et al, , 2004.…”

“…The analysis of the shape and arrangement of the epidermal cells and other foliar structures such as trichomes and papillae has provided new evidence for phylogenetic and taxonomic discussion (Alvin et al, 1980;Barron and Buades, 2002). Cuticle analysis has been used to revise the phylogeny of the genus Pinus L and to classify it into sections, subsections and subgenera (Yoshie and Sakai, 1985;Kim et al, 1999;Whang etal., 2001Whang etal., , 2004.…”

Keywords: plant taxonomy plant variation Iberian Peninsula epidermal characteristics needles PinusTaxonomic differences in the needle epidermis characteristics of Pinus sylvestris L. and Pinus uncinata Ramond ex DC. from two Iberian populations were sought; such information could help identify these species when pollen analysis and the inspection of wood anatomy fails. The features of the cuticle are commonly well preserved in the fossil record. Although the epidermal patterns of the examined taxa were similar, qualitative differences were seen in the subsidiary and guard cells. P. sylvestris showed small subsidiary cells homogenously arranged around the opening of the epistomatal chamber, while P. uncinata showed small, lateral subsidiary cells and nondifferentiated subsidiary cells in the polar position. The aperture of the epistomatic chamber of P. uncinata was also larger in diameter (15.1 ±1.8 um P. sylvestris; 21.1 ±2.8 umP uncinata). Principal components analysis and discriminant analysis was performed on the features of the guard cells characterising the size and shape of the articular thickenings -all the variables analysed can be measured in disperse stomata in microscope preparations for pollen analysis. Significant differences were found in the upper woody lamellae width and the coefficient associated with the shape of the medial lamellae borders (discriminant analysis weighting 0.739 and 0.826 respectively). Other significant parameters included the coefficient associated with the relative size of the medial lamellae border width of the guard cells with respect to the distance between the external limits of the medial lamellae borders, and the length of the upper woody lamella. Different light regimens appeared not to significantly affect the variability of the studied features.

“…In the case of conifer needles, the extent of development of epicuticular waxes depends on species (e.g., Whang et al, 2004), and their distribution on the leaf surface also varies among species (e.g., Burkhardt et al, 1995;Yoshie and Sakai, 1985).…”

In determining the effect of aerosols on forest trees, it is necessary to estimate the deposition of aerosols to forests. To this end we must consider the arboreal factors that influence the deposition of aerosols on forest trees. This paper examines such relevant factors as canopy shape, shoot structure, and leaf surface structures. Laboratory and field experiments in urban areas show that these factors play an important role in the deposition of aerosols on trees. SEM-EDX analyses have determined the chemical composition of particles deposited on the surfaces of tree leaves in urban areas. In forests, however, details of aerosol particles deposited on leaf surfaces is not known, and the effect of abiotic factors such as rainfall, fog and wind has not been determined. Further information is needed, including experimental data about the aerosols deposited on leaf surfaces of trees in a forest, taking into account canopy shape, leaf surface structures and tree phenology.

“…The stomata of many gymnosperms [9] and a few angiosperms appear to be partially blocked by filamentous waxes [10]. In the genus Pinus, the stomatal Florin ring and the stomata lantechamber [11] are covered with tubular epicuticular waxes, and this structural wax distribution reaches surrounding areas in the stomatal rows. These waxy plugs occlude the entrance of stomata, particularly in conifers [12] [13].…”

Tropospheric ozone is a worldwide phenomenon causing injuries to forest trees. Californian ponderosa and Jeffrey pines are well known for their sensitivity to ozone, while other pine species have varied in their susceptibility. Sensitive pine species are known for their chlorotic mottle and tip burn symptoms, caused by ozone air pollution. Epistomatal wax plugs and filamentous waxes around stomata are typical for pine needle surfaces. In this study, we investigated epistomatal and epicuticular needle waxes in eight species of field-grown pines in 1985, 1986 and 2006. The epistomatal wax plugs were present in asymptomatic needles without chlorotic mottle (23% of needles). A lack of wax plugs in needles with chlorotic mottle and tip burn symptoms was common (76% of needles). More abundant existence of mottling associated with stomata without wax plugs in twoyear-old needles, compared with one-year-old needles (43% and 33%, respectively), indicated chronic injury development over time.
