“…Furthermore the hairs can be alive or dead, calcified, silicated, or neither and the protoplast can vary greatly in size, or be absent (Esau 1977). As with waxes (Gonzalez et al 1996;Gordon & Percy 1999), the extent to which hairs develop is dependent on both species and environment (Karabourniotis et al 1992;Liakoura et al 1997;Filella & Peñuelas 1999). Accordingly, the classification of hairs and waxes that we have employed in this study is necessarily coarse, but is required if meaningful relationships are to be obtained between leaf hair-type and leaf reflectance.…”

Total reflectance of ultraviolet and photosynthetically effective wavelengths was measured for a range of different leaf types. Two approaches were employed. Firstly, reflectance of monochromatic wavebands at 330 and 680 nm was measured for a total of 45 different species covering a wide range of genera. In the second, specific leaf types that displayed different degrees of reflectance were treated to remove hairs and waxes that contributed to their reflectance. Selected waxy and non-waxy leaves were also studied in more detail over the spectral range 270-500 nm. It was found that both pubescence (presence of hairs) and glaucousness (presence of a thick epicuticular wax layer) had marked effects on total reflectance. Pubescent leaves tended to be more effective in reflecting longer wavelengths than ultraviolet radiation. The extent of this effect depended on hair type. Glaucous leaves demonstrated that surface waxes were very effective reflectors of both UV and longer wavelength radiation.

“…Hence flavonoids play an adaptive role in water stress regulation (Gitz and LiuGitz, 2003). UVB radiation can also affect wax biosynthesis (Gordon and Percy, 1999) and ethylene evolution (A.-H.-Mackerness, 2000), which differ with species, plant age, and environmental cues, such as humidity, temperature, light quality and quantity.…”

The content of nonacosan-10-ol and n-alkanes in needle waxes of twelve Pinus taxa (Pinus halepensis, P. heldreichii, P. mugo, P. nigra ssp. nigra, P. nigra ssp. dalmatica, P. peuce, P. pinaster, P. pinea, P. ponderosa, P. strobus, P. sylvestris, and P. wallichiana) were examined. In eight Pinus taxa (except of P. halepensis, P. pinaster, P. heldreichii and P. peuce) nonacosan-10-ol contents were examined for the first time. In all examined pines C29, C27 or C25 were the main n-alkane compounds. C range was mainly 18-33. In six Pinus taxa (P. mugo, P. nigra ssp. dalmatica, P. sylvestris, P. pinea, P. strobus and P. wallichiana) CPI and ACL values were examined for the first time. In the plane of Axis 1 (PCA), P. strobus, P. mugo, and P. wallichiana were strongly separated from P. heldreichii and P. pinea. In the plane of Axis 2, P. peuce, P. strobus, and P. wallichiana as well as P. heldreichii and P. pinea diverged from other examined species. In DA P. heldreichii, P. strobus, P. peuce, and P. wallichiana diversed. CA divided sections Pinus and Pinaster from section Strobi.
