Increasing disturbance events (forest fires, windstorms, pest outbreaks) associated with climate change are creating new ecological restoration challenges.

seed germination and seedlings of Abies spp. are: temperature treatments, scarification, elongation of adventitious shoots, organogenesis, somatic embryogenesis, callus formation and the use of growth. Germination is extremely variable but is seldom over 50% [14,71,54]. Li and others found that in collections from coastal British Columbia, light increased germination rates in unstratified seed (light/dark germination= 89/80%) but had no significant effect on germination rates of stratified seed (92/93%, p=).
Abies spp. in general have been shown to need a period of cold stratification to break dormancy and germinate, but this can be very time consuming. In this study, hydropriming by itself and in combination with biopriming was carried out on Abies hickelii and Abies religiosa seeds.
For biopriming, three species of plant growth promoting rhizobacteria (Pseudomonas fluorescens, Cited by: 6. A question that many BC nurseries are asking is whether there is good seed sanitation method for Abies spp.
Some early work with hydrogen peroxide indicated that the proportion of fungi on the seed coat could be reduced with hydrogen peroxide, but in general (one exception) a decline in germination was found (Edwards and Sutherland ).
In both species of Abies, stratification/redrying treatments increased germination percentages and rates. Also, after seeds of A. grandis received a routine cold stratification treatment, drying them to 15, 25 or 35% moisture content prior to sowing them increased germination percentages and rates compared to stratified, nondried (45% moisture.
Lack of seed germination at certain times and suitable conditions are a big problem for seed researchers, botanists, and farmers. Seed dormancy in agricultural ecosystems due to use of inputs and energy is a negative features; Thus seed dormancy is a factor in the lack of a uniform seedbed and reduced yield.
Abies is an evergreen Tree growing to 45 m (ft) by 15 m (49ft) at a fast rate. It is hardy to zone (UK) 4 and is not frost tender. It is in leaf all year, in flower from April to May, and the seeds ripen from September to October.
The species is monoecious (individual flowers are either male or female, but both sexes can be found on the same plant) and is pollinated by Wind. COVID Resources.

Artificial seeds are artificially encapsulated somatic embryos (usually) or other vegetative parts such as shoot buds, cell aggregates, auxiliary buds, or any other micropropagules which can be sown as a seed and converted into a plant under in vitro or in vivo conditions.

Picea abies, the Norway spruce or European spruce, is a species of spruce native to Germination of Abies spp. seed book, Central and Eastern Europe. It has branchlets that typically hang downwards, and the largest cones of any spruce, 9–17 cm (3 1 ⁄ 2 – 6 3 ⁄ 4 in) long.
It is very closely related to the Siberian spruce (Picea obovata), which replaces it east of the Ural Mountains, and with which it Clade: Tracheophytes. Propagation by stem cuttings is the most commonly used method to propagate many woody ornamental plants.
Stem cuttings of many favorite shrubs are quite easy to root. Typically, stem cuttings of tree species are more difficult to root. However, cuttings from trees such as crape myrtles, some elms, and birches can be rooted. The genus Abies is generally characterized by low germination ranging from 25% to 60% (US Department of Agriculture, Germination of Abies spp.

Abstract. The Abies genus belongs to the family Pinaceae. Phylogenetically the genus is considered to be most closely related to Cedrus and relatively distantly related to Picea, Pinus and Larix (Farjon, ).The species belonging to the genus are restricted to the northern hemisphere ranging from North of the Polar Circle in Siberia (Abies sibirica) to Guatemala Cited by: Picea glauca, the white spruce, is a species of spruce native to the northern temperate and boreal forests in North America.
Picea glauca was originally native from central Alaska all through the east, across southern/central Canada to the Avalon Peninsula in Newfoundland. It now has become naturalized southward into the far northern United States border states like Montana, Class: Pinopsida.
The new edition of Seeds contains new information on many topics discussed in the first edition, such as fruit/seed heteromorphism, breaking of physical dormancy and effects of inbreeding depression on germination. New topics have been added to each chapter, including dichotomous keys to types of seeds and kinds of dormancy; a hierarchical dormancy classification system.
