Western White Pine, P. monticola. Also called Silver Pine. Bark whitish or reddish and Lodgepole smooth; needles in 5's and very Pine slender, 2"-4"long; 6"-l0" long cones are very slender when. Cone and seed yield results were compiled from various field stations in the South over a year period. They showed that survival of cones from cross-pollinations was less than 40 percent, seed yields per cone about half those from wind pollinations, and interspecific crosses generally less productive than intraspecific pollinations.
White fir will seed into the understory of ponderosa pine stands or in mixtures of ponderosa pine, Douglas-fir, quaking aspen, and southwestern white pine. Many habitat types in the white fir series in the Southwest are dominated by Douglas-fir and ponderosa pine in mid-seral stages, with white fir steadily gaining dominance as succession. Allium sativum, commonly known as garlic, is a species in the onion genus, close relatives include the onion, shallot, leek, chive, and rakkyo. Dating back over 6, years, garlic is native to central Asia, and has long been a staple in the Mediterranean region, as well as a frequent seasoning in Asia, Africa, and Europe.

After that, seed production depends on individual tree vigor and character of crown or possibly on heritable capacity to set and bear cones.
Seed yields for western white pine range f to 70,/kg (14, to 32,/lb) with an average of 59,/kg (27,/lb).

The optimal time for control pollinations was at cone stages 4 and 5 and optimal amount of pollen per pollination bag was mL.

A spruce is a tree of the genus Picea / p aɪ ˈ s iː ə /, a genus of about 35 species of coniferous evergreen trees in the family Pinaceae, found in the northern temperate and boreal regions of the Earth.
Picea is the sole genus in the subfamily s are large trees, from about 20–60 m (about 60– ft) tall when mature, and have whorled branches and conical form.
Western pine shoot borer, Eucosma sonomana, pheromone release of 10–20 g ha− 1 has been shown to reduce damage by over 65% in ponderosa pine plantations in the western United States.
Many forest management practices are available for use to reduce the impacts of insect populations. pollen-cone and seed-cone buds is resumed. Pollination occurs in May and is well synchronized with female receptivity [14,63].
Fertilization occurs in early July, 4 to 5 weeks after pollination. In early August, meristems and cotyledons of embryos develop and mature by the end of the month. Cones change from green to purple at maturity [6, Eastern white pine seeds are favored by black bears, rabbits, red squirrels and many birds, especially red crossbills.
While potentially damaging to the trees, the bark is eaten by mammals such as beavers, snowshoe hares, porcupines, rabbits and mice. 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, Minnesota. The yield in (Table ) was similar to that in (Table ), seed per cone.
Clones varied widely in total seed per cone all 3 years (Tables, and ), with a three lo fourfold difference between those having the largest and those having the smallest yields per cone. This banner text can have markup. web; books; video; audio; software; images; Toggle navigation.

The combined GA/girdling treatment significantly increased female flowering, numbers of seed cones and pollen cones, and the proportion of trees bearing cones. Thus, GA plus girdling can enhance cone and seed production in young seed orchards. 9 of the 22 SSR markers developed for the Pollen Contamination Study were used to measure pollen.
The estimated critical elevations for lodgepole pine and western larch are m (Rehfeldt, ) and m (Rehfeldt, ), respectively.
In contrast to these results, western white pine exhibits very little differentiation among populations (Rehfeldt, ; Rehfeldt et al., ). found pollen deposition in temperate pine forests in Korea to be c. % that of total litterfall by weight, with nitrogen inputs corresponding to 1% and 6% of total nitrogen and phosphorus, respectively.
Pine pollen may nonetheless be a significant source of nutrients during the critical early growing period. The red crossbill eats some western larch seed. Seed-eating small rodents prefer larger Douglas-fir and pine seed but consume some western larch seed [9,]. Squirrels cut and cache western larch cones in years when other conifers have poor crops [,].

It is a minor species in five types: Engelmann Spruce-Subalpine Fir (Type ), White Fir (Type ), Western White Pine (Type ), Aspen (Type ), and Lodgepole Pine (Type ).
