Abstract. The natural range of Scots pine (Pinus sylvestris L.) is the widest among the pine species (Mirov ).It is found at latitudes from 70°N in northern Scandinavia to about 40°N in the south, in Turkey and Spain, and at longitudes from 10°W in the west, with a small population in Scotland (6°W) to °E in the east in Russia (Figure 1). Its seeds are winged and thought to be dispersed primarily by wind and gravity (e.g. Fowells, ), but are food items for: a number of mammals including mice, voles, shrews and chipmunks (Gashwiler, ); birds including the Winter Wren (Troglodytes hiemalis), Pine Siskin (Carduelis pinus), Song Sparrow (Melospiza melodia), Golden
The white pine weevil Pissodes strobi (Peck) (Coleoptera: Curculionidae) is a major pest in spruce plantations in western Canada. Larvae, mining down the axis of the tree, girdle the leader killing at least 2 and sometimes up to 4 years' growth. Existing knowledge of the biology and behaviour of P. strobi has been derived mostly from studies in eastern white pine and Sitka spruce hosts Nitrogen (N) concentrations in the range of to % generally result in seedlings that exhibit enhanced field survival and height growth. The benefits of nutrition, however, can be altered by its effect on seedling size, degree of frost hardiness, and levels of ://

Both lodgepole pine and jack pine initiated spring growth earlier and had greater responses to experimental warming in bud phenology than black spruce and white spruce, suggesting a greater The objective of this study was to compare volume growth and external timber quality properties of lodgepole pine (Pinus contorta Dougl.
var. latifolia) stands planted in different spacings ( In shelterwood, the height growth of seedlings of Scots pine and Lodgepole pine was significantly reduced due to partially factors associated with the distance to the nearest shelter tree (Strand This thesis reports the findings of two complementary investigations on boron, copper and iron nutrition of lodgepole pine and Douglas-fir.
The primary aim of the first study was to determine the critical levels of boron, copper, total iron and "active" iron for lodgepole pine grown under controlled conditions in the greenhouse.
The second study, conducted at five different field locations in Most studies on plant phenology have focused on leaf phenology because of its direct role in photosynthetic production (Menzel ), while much less is known about root phenology Winter and spring cold hardiness and bud flush phenology show weaker and more variable patterns of variation among populations and show strong plasticity in response to variation in chilling and heat sum accumulation (Duputié et al.

Other trees that commonly occur with white spruce include red spruce, yellow birch, jack pine, and sugar maple in the east; and subalpine fir and Rocky Mountain Freezing stress is one of the most important limiting factors determining the ecological distribution and production of tree species.
Assessment of frost risk is, therefore, critical for forestry, fruit production, and horticulture. Frost risk is substantial when hazard (i.e., exposure to damaging freezing temperatures) intersects with vulnerability (i.e., frost sensitivity).

Gaz – Winter coloration and growth of jack pine in the nursery as affected by Provenance studies of many species of conifers have identified substantial proportions of genetic variation for characters such as germinability, growth, disease resistance, times of bud break and bud set, susceptibility to frost damage, and growth form (Wright, ).One indication of the magnitude of variation among individuals is the range of values for maximum photosynthetic capacity Bud temperature controls the rate of ontogenetic bud development (Sarvas,), determines flower bloom and leaf flush phenology (Kozlowski, ; Hänninen, ; Saxe et al., ), and governs patterns of tree crown mortality during forest fires (S.

This work has shown that host phenology is as important as host preference in determining the survival and successful development of L.
monacha larvae. For example, when the larvae hatch before foliage bud burst, the presence of male flowers or buds on Pinus sp. is critical to larval survival and growth ( Contents.

Over the ensuing century, concepts on what is meant by a quality seedling have evolved to the point that these assessments now provide value to both the nursery
