    The distribution of genetic variation among and within provenances, the extent of genetic control in growth and bud phenology traits and potential of early testing of height growth were investigated in open-pollinated families from 57 provenances of white spruce (Picea glauca) from Quebec and Ontario, Canada. Provenances and families within provenances showed significant genetic variation.   On average, white spruce wood from plantations showed a good performance for the shaping process, with 77 percent of pieces graded good to excellent (Table 1). Lihra and Ganev (11) and Williams and Morris (16) also reported a high percentage (74%) of good to excellent pieces for the same wood, but grown in natural forests.

    Needle primordia in buds and branch lengths were assessed in the crown of a plantation-grown white spruce tree. There was a gradation in needle primordia in buds in branches within the crown. The largest number of primordia was in the terminal bud of the leading main stem shoot, with the number in first-order whorl lateral shoot terminal buds decreasing from whorl 1 to whorl 4, below which.

Species, Ontario has many white spruce provenance test trials with sources from across the province and the country. Provenances from across Ontario have been planted at a Kakabeka test site to determine the top performing seed sources.

This thesis explores the variation in height between provenances at this test site to determine the climatic. Additional Physical Format: Online version: Morgenstern, E. Kristian (Erwin Kristian), Best white spruce provenances in Ontario.

Ottawa: Science Branch. This report is based on the performance of 15 provenances of white spruce from Ontario and Quebec Provinces in Canada, a region that includes the typical variety-P. glauca var. glauca. Racial variation of white spruce has not been well known.

The first intensive studies were initiated by the Petawawa Forest Ex-periment Station, Canada Department of. and those from other provenance tests of white spruce (Teich L) Carlisle and Teich () estimated that. an increase in yield of 15 percent can he obtained by using superior provenances of white spruce for reforestation.

The objective of my study was to evaluate height-growth performance of these range-wide white spruce seed-sources after. traits, and field performance of selected white spruce provenances originating from throughout the species range.

Tree height, survival, cold hardiness, hydraulic, and wood anatomical traits were measured in a year-old common garden trial, located in the center of the species range. Provenance performance included all combinations. Here, we study the relationship among climate, a wide range of physiological traits, and field performance of selected white spruce provenances originating from throughout the species range.

how provenances from other provinces perform in Alberta. Provenance studies have shown that white spruce exhibits high genetic variation among populations.

In the eastern part of its natural range, provenances with highest growth potential occur in southeastern Ontario (e.g., Teich et al. The three Russian provenances were also growing better than the local white spruce, but were poorer than white spruce introduced from Ontario.

This is because both the Russian Norway spruce and local Wisconsin white spruce are variable in growth, and the Ontario white spruces are much more uniform, which gives them a better average height.

The white spruce tree, also known as cat spruce and skunk spruce, is a coniferous tree found across North America.

Impacts of nursery short-day treatments on the survival, growth and needle damage of about 5, 1 + 0 container white spruce (Picea glauca [Moench] Voss) seedlings from a single seedlot were studied for two growing seasons following planting on J at four boreal reforestation sites in Northern Alberta, Canada of varying soil texture, drainage, aspect, slope, and slope position.

We anticipate the usefulness of such information in: (1) the development of an ISAM strategy to adapt white spruce to climate change within and outside Ontario, (2) assessing vulnerability of existing forests to climate change, and (3) contributing to policies for conserving genetic.

Bedrock classification for test sites and provenances by limestone or non-limestone parent material was done using a data set of the Ontario Geological Survey.

Local and regional timber shortages may be ameliorated via planting improved stocks with higher yields.

A total of seed sources (provenances) of white spruce (Picea glauca (Moench) Voss) from Ontario and western Quebec were established at a greenhouse and in six field trials throughout Ontario. Growth and phenological variables were measured over three growing seasons. The goal of this study was to evaluate the magnitude of the potential impacts of climate change on the growth performance of local white spruce populations.

Such evaluation can only be obtained, if there is sufficient genetic variation among populations, which would be shaped by natural selection incurred by differential climatic conditions.Nursery indications of white spruce provenance variability in northwestern Ontario.

There's simply nothing bad about this tree.

The White Spruce is one of the most beautiful and practical evergreens you can add to your landscape. Incredibly tolerant and providing both ornamental and functional value in colder climates, it's the perfect tree for anyone in zones 2 to 6. The White Spruce will grow, no matter what.
