On acidified soil, the growth of Eucalyptus is seriously restricted by aluminum (Al) stress. Therefore, breeding species with excellent Al tolerance, developing genetic potential species, and improving tolerance to stress are important for sustainable development artificial forests. By observing occurrence distribution main reactive oxygen (ROS) nitrogen (RNS) in root tips seedlings under stress, this study analyzed change physiological indexes The antioxidant enzymes activities different induced resulted ROS RNS contents, ultimately resulting differing degrees membrane lipid peroxidation. In addition suppressions relative elongation activity, accumulations soluble sugar, protein, proline can be used as indicators sensitivity species. This may an determinant differences among accumulation roots E. grandis tereticornis severe oxidative nitrification urophylla × was stronger than that tereticornis.

These results provide theoretical support tree areas acidic soil. better both have been due

Abstract The world’s natural forests have a long history of being destroyed, degraded, and simplified. Resilient forest management therefore must often start with restoration. Restorative actions can employ well-developed silvicultural methods, but an emphasis on generating compositional diversity structural complexity. Forest regeneration sets the stage for next many decades development, so requires thoughtful selection plant materials attributes future desired forest, including its ability to thrive in both current climates. Many homogenous, monotypic plantations second-growth be modified include old-growth characteristics (such as standing fallen deadwood, canopy gaps, multilayered canopies), or serve nurse crops establishment slow-growing native tree species. Other aspects ecosystem restoration may need focus reintroduction keystone species (including animals), control invasive landscape integrates these improvements integrity other land covers agricultural residential uses) assure socio-ecological resilience. Guidelines recognition first protect existing halt processes degradation, then undertake broad stakeholder involvement promoting biodiversity adaptability framework adaptive management. provides numerous opportunities design redesign
