Effects of stratification and temperature on seed germination speed and uniformity in central Oregon ponderosa pine (Pinus ponderosa Dougl. ex Laws.) Book January with 44 Reads How we. Variation in speed of seed germination was investigated among ponderosa pine trees representing locations in central Oregon.

Results suggested that at least some of the geographic variation is. Abstract. This chapter summarizes current technology concerning cone collection and seed processing, testing, storage, and stratification for the six major conifer species—Douglas-fir, ponderosa pine, lodgepole pine, noble fir, white fir, and western hemlock—produced as seedlings in.

We compared carbon storage and fluxes in young and old ponderosa pine stands in Oregon, including plant and soil storage, net primary productivity, respiration fluxes, eddy flux estimates of net ecosystem exchange (NEE), and Biome‐BGC simulations of young forest (Y site) was previously an old‐growth ponderosa pine forest that had been clearcut inand the old forest (O.

Stratification was shown to have a greater effect on the rate of germination than on the germinative capacity. The longer the stratification period the less sensitive the seed was to incubation temperature.

The shorter stratification periods (30 and 40 days) showed little or no significant effect on the rate of germination of the relatively. All results are based on the average ±SD of six independent NMR experiments (replicates). Each replicate contained a single seed for western white pine, ponderosa pine, and loblolly pine, and 12 seeds for lodgepole pine.

From analysis of the NMR spectra. In a study of the problems met in testing germination of coniferous tree seed, special attention is given to the variability between different seedlots of the same species.

Known and suspected causes for this variability are discussed. These include seed source, genetic constitution of individual trees, seed maturity, treatments during the commercial extraction process and storage conditions.

improve the germinative energy and germinative capacity of the seed collected. All three objects can be achieved by one simple treatment, that is, the careful selection of seed trees and the complete isolation of the crowns of these seed trees by thinnings.

NOLAND1 and ANDRE´E E. MORNEAULT2 1. Forest inventory data on ponderosa pine plots in Oregon show that the greatest proportion of plots exist in stands ∼ years old, indicating that a majority of stands are approaching maximum carbon storage and net carbon uptake.

Our data suggests that NEP averages ∼ 70 g C m −2 year −1 for ponderosa pine forests in Oregon. About. California black oak is most common in Pacific ponderosa pine (Pinus ponderosa var. ponderosa; hereafter, ponderosa pine) and mixed-conifer forests, where it is more often an associated than a dominant species [,].

California black oak cooccurs with ponderosa pine throughout nearly all of California black oak's distribution [61,]. Ponderosa pine ecosystems—Graham and Jain dominated by ponderosa pine, these or similar stages may develop in less than years but in other systems, such as Pacific coastal Douglas-fir (Psuedotsuga menziesii (Mirbel) Franco var.

menziesii), it may take in excess of 1, years for the full compliment of structural stages inherent to the system to develop (Franklin and. Kate A. Clyatt, Christopher R. Keyes, Sharon M.

By: Curtis, James D. - Intermountain Forest and Range Experiment Station (Ogden, Utah) Publication info: Ogden, Utah:Intermountain Forest and Range Experiment Station, The ponderosa pine forests in the Davis Mountains of western Texas recently experienced a major mortality event caused, in part, by an extended regional drought that predisposed trees and stands to mortality from both western pine beetle and wildfires.

The loss of many overstory pines and the scarcity of natural ponderosa pine regeneration pose a considerable challenge to restoration.

Cone production by ponderosa pine, lodgepole pine, western larch, and Douglas fir was reduced by SO 2 from smelters (Scheffer and Hedgcock, ). In the Urals SO 2 from a smelter reduced the weight of seed cones of Scotch pine by 32 to 50%, of pollen cones by 23 to 32%, and of seeds by 12 to 15% (Mamajev and Shkarlet, ).

Ponderosa pine is the most common tree species planted in northwest Patagonia, Argentina. Rotation periods and relative high harvest and transport costs make the eventual trade of carbon offsets an attractive option to complement wood production.
