5 results for “seed viability”
Black spruce seed viability from seed rain traps in the 2004 burns off the Steese, Taylor, and Dalton Highways, collected in 2005-2007.
This dataset contains viability estimates of black spruce seed collected in traps at 39 intensive study sites within the 2004 burns of interior Alaska. Data are presented as raw data from trap collections at each site. All sites were in communities dominated by black spruce before burning, and were located 100 to 600 m from the road, beyond the range of any visible road effects and away from any signs of other human disturbance.
Black spruce seed availability and viability after fire, Northwest Territories, Canada
<p>Context : Black spruce ( Picea mariana ) is an important conifer in boreal North American that develops a semi-serotinous, aerial seedbank and releases a pulse of seeds after fire. Variation in post-fire seed rain has important consequences for black spruce regeneration and stand composition.</p> <p>Aims : We explore the possible effects of changes in fire regime on the abundance and viability of black spruce seeds following a very large wildfire season in the Northwest Territories, Canada (NWT).</p> <p>Methods: We measured post-fire seed rain over two years at 25 black sprucedominated sites and evaluated drivers of stand characteristics and environmental conditions on total black spruce seed rain and viability.</p> <p>Results : We found a positive relationship between black spruce basal area and total seed rain. However, at high basal areas this increasing rate of seed rain was not maintained. Viable seed rain was greater in stands that were older, closer to unburned edges, and where canopy combustion was less severe. Finally, we demonstrated positive relationships between seed rain and seedling establishment, confirming our measures of seed rain were key drivers of post-fire forest regeneration.</p> <p>Conclusion: These results suggest that black spruce recruitment after fire may be reduced with projected increases in fire activity.</p>
Diversity of Reproductive Characters, Reproductive Capacity, and Viability of Agave Seeds
<p>Raw data of morphological variables of reproductive characters of Agave landraces used for the production of pulque in 10 localities of Tlaxcala. These data were used to analyze and describe the morphological diversity of these varieties.</p>
