Summary Nine promising taxa of ‘oil mallees’ were planted in twin row alley culture at twelve sites across the Western Australian wheatbelt. Two harvest regimes were imposed (i) 2.5-year-old saplings cut to ground level in summer and their coppice shoot biomass harvested twelve months later, and (ii) 3-year-old saplings cut in winter and coppice shoots

Abstract Our objective was to identify mechanical, chemical or a combination of treatments that would convert dense stands (over 7000 stems ha−1) of small trees into widely spaced, large trees to maximize lumber production and pasture improvement. A randomized complete block design was utilized with four replicates and six treatments.

Elevational changes in vegetation are associated with changes in environmental factors, an example of which is provided by the shade-tolerant Abies mariesii and less shade-tolerant Abies veitchii, which dominate forests at high and low elevations, respectively, in subalpine zones of central Japan.

Investigation of cadmium pollution in the spruce saplings near the metal production factory
Toxicology and Industrial Health, 2013Toxic metals such as lead and cadmium are among the pollutants that are created by the metal production factories and disseminated in the nature. In order to study the quantity of cadmium pollution in the environment of the metal production factories, 50 saplings of the spruce species at the peripheries of the metal production factories were examined ...

Aeroponics, a soilless plant culture method, was used to produce Acacia mangium saplings associated with arbuscular mycorrhiza (AM) fungi. A. mangium seedlings were first grown in multipots and inoculated with Endorize, a commercial AM fungal inoculum. They were then, either transferred to aeroponic systems or to soil.
