    Seed dispersal, the way that seeds travel, is super intriguing. A friend and former co-worker from my High Park summers has gotten me hooked on this topic over the years. There are the many different structures which allow seeds to travel by the wind, like maple keys and milkweed’s fluffy seeds. seedling populations in Southern Ontario pine plantations to sample the dispersal of seed of hardwood trees in remnant woodlots in the region. The following questions were addressed: (1) Do hardwood seedlings normally establish in pine plantations and if so, what is the size-class structure and spatial distribution of these populations? (2.

    Production and dispersal of longleaf pine (Pinus palustris Mill.) seeds were sampled in , , and on the Escambia Experimental Forest in southwest Alabama. Two transects of seed traps were established at right angles to each of four forest walls enclosing a rectangular acre by: 3. The proper selection, treatment of sowing southern pine seeds will deter-mine whether a crop of high-quality pine seedlings can be grown. The goal for any nursery should be to have seed lots with greater than 90 percent ger-mination and losses, after emergence, of less than 10 percent (Barnett et al. ).

    winter. Thus, dormancy is an adaptive trait that optimizes the distribution of germination over time in a population of seeds. Seed dormancy is generally an undesirable characteristic in agricultural crops, where rapid germination and growth are required. However, some degree of dormancy is advan- tageous, at least during seed by: 2.

(3) Fire (serotinous dispersal) The seeds are mostly small and winged, and are anemophilous (wind-dispersed), but some are larger and have only a vestigial wing, and are bird-dispersed.

At maturity, the cones usually open to release the seeds, but in some of the bird-dispersed species (e.g. Whitebark Pine), the seeds are only released by the. Wind dispersal capacity of pine seeds and the evolution of different seed dispersal modes in pines Craig W.

Loblolly pine has good seed crops every 2 or 3 years and slash has good seed crops at about 3-year intervals. Shortleaf pine has good seed crops every 3 to 5 years.

Longleaf pine, however, does not have good seed crops except every 5 to 7 years. It is important to observe flower and cone production when making plans for natural Size: KB.

The seeds of a bishop pine germinate only after exposure to the extreme heat of a forest fire. Evaluate the significance of this structural adaptation.

The extreme heat allows the germination of the seed which is desired because of the forest being wiped out by the fire. Seed Dispersal on *FREE* shipping on qualifying cturer: Benediction Classics. To prevent seed predation and promote dispersal, seeds exhibit physical or chemical defenses.

Collared peccaries (Pecari tajacu) cannot eat some hard seeds, but can digest chemically defended seeds. Slash Pine Tree (Pinus elliotti) The Slash Pine is found along the coast from South Carolina to Florida, West to Southeastern Mississippi and Louisiana.

It is an important timber species in these areas. It is a tall tree growing over feet tall. Growth Rate: Fast growing Soil Type: Found in wet flat woods, near coastal sands and sandy ridges.

Seed dispersal and seedling establishment of Korean pine (Pinus koraiensis) were studied in Hokkaido, Japan, by means of: (1) observation of seed harvest and seed dispersal by animals; (2) distribution of the offspring (seedlings, saplings and juveniles); and (3) sowing experiments (1) Red squirrels (Sciurus vulgaris orientis) harvested and transported Korean pine cones away from seed Cited by: Seed dispersal: Studies of pitch pine seed dispersal were lacking as of the writing of this review ().

Prescribed Fire. Shortleaf pine is a fire-adapted species, or it tolerates frequent, low temperature fires (Fig. Historic records indicate this adaptation has enabled the species to persist in the landscape through time.

The older-school favors the “pull-up” technique where the seedling is placed into the planting hole and then pulled up 3 to 10 cm (and the root-collar is about 1 to 5 cm below the soil surface).

This action purportedly improves field performance by straightening out the Size: KB. seedling size: ” Jack Pine (Pinus banksiana) Jack Pine is an open-crowned tree with spreading branches and stout needles.

This tree does well in dry, sandy soils or mineral beds. The pine cones are serotinous, meaning they open under extreme heat associated with wildfire.

Seedling densities 13 months postfire were low ( m−2), but seedling mortality also was low (%). Aerial seed bank size increased from north-facing to south-facing slopes and from high-severity to low-severity burns.

Seedling recruitment was unrelated to burn severity and increased with the size of the canopy seed bank (cone density).Cited by:   Seed density, seed colour and the number of seed damaged by birds were monitored for several months, after a late-spring fire, in two Aleppo pine (Pinus halepensis Miller) stands growing in South Italy.

In one stand (S(1)) the trees were completely burned ('charred’), in the other one (S(2)) the trees were only ‘scorched’, with a crown in part still alive after fire. 37% and 61% of seeds Cited by:   Forums > Plant Central > Seed Starting / Propagation > seed and seedling Discussion in ' Seed Starting / Propagation ' started by Theodoros,
