متن کاملInfluence of salicylic acid pre-treatment on emergence and early seedling growth of cucumber (Cucumis sativus)under salt stress
Salicylic acid (SA) is a common, plant-produced signal molecule that is responsible for inducing tolerance to a number of biotic and abiotic stresses. An experiment was therefore conducted to test whether the application of SA at various concentrations (0, 0.25, 0.50 or 1.0 mM) through a seed-soaking method would protect cucumber (Cucumis sativus L.) seedlings subjected to salt stress. Aft...
متن کاملShrub Microsite Influences Post-fire Perennial Grass Establishment
Woody plants can cause localized increases in resources (i.e., resource islands) that can persist after fire. We tested the hypothesis that burned sagebrush subcanopies would have increased seedling establishment and performance of post-fire seeded perennial bunchgrasses compared to burned interspaces. We utilized five study sites in southeastern Oregon. The area was burned in a wildfire (2007)...
متن کاملEffects of microsite conditions on seedling establishment on the foreland of Coleman Glacier, Washington
Questions: How do physical microsite conditions of microsites affect germination and seedling survival in different successional stages? Do different species germinate in similar microsites in a given successional stage? Location: Coleman Glacier foreland, Mount Baker, Washington State, USA. Methods: Two methods were used to characterize safe sites. 1. Grids of 300 10 cm × 10 cm plots were loca...
متن کاملResearch Note Shrub Microsite Influences Post-Fire Perennial Grass Establishment
Woody plants can cause localized increases in resources (i.e., resource islands) that can persist after fire and create a heterogeneous environment for restoration. Others have found that subcanopies have increased soil organic matter, nitrogen, and carbon and elevated post-fire soil temperature. We tested the hypothesis that burned sagebrush subcanopies would have increased seedling establishm...
