Understanding ecosystem resilience to human impacts is critical for conservation and restoration. The large-scale die-off of New England salt marshes was triggered by overfishing and resulted from decades of runaway crab grazing. In 2009, however, cordgrass began to recover, decreasing die-off -40% by 2010. We used surveys and experiments to test whether plant-substrate feedbacks underlie marsh...

The production of argan seedlings in nurseries is considered a crucial step for the success any forest regeneration program since it increases rate survival and growth. Therefore, substrate container play vital role seedling production, while use shade may improve soil moisture decrease water stress plant. This study aims to determine effects these factors their interactions. For this, four lev...

The effect of a variety factors on the survival of several rhizobia strains on inoculants and inoculated seeds has been evaluated. Since the rhizobia strains showed different cell-density-evolution patterns on peat-based inoculants and on inoculated seeds, several inoculant formulations with highly effective Rhizobium/Bradyrhizobium strains (for Lupinus, Hedysarum, Phaseolus and Glycine max.) w...

Isolates of Fusarium were discovered in peat soil samples collected from peat swamp forest, waterlogged peat soil, and peat soil from oil palm plantations. Morphological characteristics were used to tentatively identify the isolates, and species confirmation was based on the sequence of translation elongation factor-1α (TEF-1α) and phylogenetic analysis. Based on the closest match of Basic Loca...

To study how ectomycorrhizas (ECMs) mediate plant performance and rhizosphere soil bacterial communities via altered physiological characteristics root carbon exudation. Tuber melanosporum-colonized uncolonized Quercus mongolica seedlings were grown on a substrate consisting of 41% peat, pumice, 9% pine bark lime. Gas exchange fluorescence system, inductively coupled plasma atomic-emission spec...

ABSTRACT Watermelon (Citrullus lanatus) is a succulent fruit and vine-like plant that cultivated in Mexico it generates employment currency for the country. However, there need to research what local organic substrates can substitute peat moss as culture medium produce watermelon seedlings of good quality at low cost. The objective this study was evaluate physical chemical properties five subst...

Commercial forest plantations in Chile are dominated by pine (Pinus radiata) and eucalyptus (Eucalyptus globulus). Tree bark is the main by-product of forestry industry has low value, but great potential for use as an agricultural substrate. However, direct fibers may cause plant phytotoxicity due to presence polyphenolic other compounds. This study aims evaluate physicochemical properties E. g...
