Clear cutting and burning affect nitrogen supply, phosphorus fractions and seedling growth in soils from a Wyoming lodgepole pine forest
Timber harvesting, with and without prescribed slash ®re, and wild ®re are common disturbances in pine forests of western North America. These disturbances can alter soil nitrogen (N) pools and N supply to colonizing vegetation, but their in ̄uence remains poorly understood for many forests. We investigated the effects of clear cut harvesting and ®re on KCl extractable N pools, net N mineralizat...
متن کاملDiscussion Solution — N and CO2 effects on pine seedling growth
General approach These data are best analyzed by multiple regression, which can address all three hypotheses in one analysis. The first two hypotheses assert positive effects of the two independent variables separately, while the third hypotheses posits a positive (“reinforcement”) interaction between them; testing the latter therefore requires a multivariable analysis. The first two hypotheses...
متن کاملNitrogen effects on seed germination and seedling growth
Recent evidence associates the persistence of invasive plant species with disturbance and fluctuations in distinct forms of mineral N in soils. We conducted soil and hydroponic experiments to investigate the influence of N form and availability on germination and seedling development of 2 invasive annual grasses, cheatgrass (Bromus tectorum) and medusahead (Taeniatherum caput-medusae) and 6 per...
متن کاملPlant growth-promoting rhizobacteria for improving nodulation and nitrogen fixation in the common bean (Phaseolus vulgaris L.)
A greenhouse experiment was performed to evaluate the effects of plant growth-promoting rhizobacteria (PGPR) on nodulation, biological nitrogen fixation (BNF) and growth of the common bean (Phaseolus vulgaris L. cv. Tenderlake). Single and dual inoculation treatments of bean with Rhizobium and/or PGPR were administered to detect possible changes in the levels of and interactions between the phy...
متن کاملEffects of overstorey canopy, plant-plant interactions and soil properties on Mediterranean maritime pine seedling dynamics
Seedling emergence, survival and early growth of the Mediterranean conifer P. pinaster were studied under closed canopy and open canopy (gaps) cover conditions in a Mediterranean forest of central Spain during two consecutive years (March 2008 to January 2010). Our main objective was to understand how overstorey structure, shrubs and soil properties influence recruitment in this species. Natura...
