Dielectric spectroscopy of Scots pine

Wood Science and Technology, 2009
Dielectric properties of Scots pine (42 trees) were compared with density, moisture content (MC), and resin acid content (RAC) (of heartwood). The samples were measured in frozen, green, conditioned and non-conditioned dry moisture states to evaluate the potential of dielectric spectroscopy in determining the wood characteristics at different stages of

Hydraulic architecture of Scots pine

1998
The hydraulic architecture of plants is controlled by internal and external variables like, inter alia, species (Huber, 1928; Zimmermann, 1978; Yang and Tyree, 1993), genotype (Neufeld et al., 1992), competition (Sellin, 1993), site fertility (Espinosa-Banclari et al., 1987; Long and Smith, 1989), stand management (Pothier and Margolis, 1988), climate (

The Large Pine Aphid on Scots Pine in Britain

1988
The large pine aphid, Cinara pinea (Mordvilko), infests a number of pines but is found most commonly on Scots pine (Pinus sylvestris).16 It is widely distributed throughout the Palaearctic, coinciding with the range of its main host plant.6 There are also numerous records from North America, where Scots pine has been introduced and grown on a ...

Needle area relationships of Scots pine in the Netherlands

Forest Ecology and Management, 1993
Abstract To analyse the foliage area characteristics of Scots pines of different sizes, 12 trees were selected out of 4 stands of different ages. From the selected trees, total needle area and needle area distribution were estimated from branch samples. Stem discs were collected to determine sapwood area at breast height.

Effect of the Pine Needle Scale on Photosynthesis of Scots Pine

Forest Science, 1973
Abstract An examination of the feeding sites of pine needle scale on Scots pine revealed that the insects' stylets enter the needle through stomata and terminate in the mesophyll tissue. Chlorotic bands result from this feeding, and photosynthesis is reduced. Forest Sci. 19:109-111.
