Bentonite as substrate conditioner under different water regimes – A Eucalyptus dunnii seedling assay
The substrate has a lot of functions in the process to develop a high-quality seedling, including the responsibility to hold water and to make the water available for the plants. A compound that can be used to hold water is bentonite. So, the research aimed to evaluate the effects of different proportions of bentonite as a substrate component under two water conditions in the production of Eucalyptus dunniii seedlings. The research was carried out in the forest seedlings nursery in Curitiba/PR - Brazil. For the treatments, bentonite substrate conditioner was used in different proportions, 0 %, 5 %, 10 %, 15 % and 20 %, in a commercial substrate (with sphagnum peat) here named as S0, S5, S10, S15 and S20 respectively, in two water regimes for the blocks. The seedlings produced with these bentonite proportions was analyzed by the height, stem diameter, dry matter (shoot, root and total), and two parameters: height/stem diameter ratio (H/SD) and Dickson Quality Index (DQI). The substrate analysis shown a contrary behavior of expected. The bentonite in the substrate for seedlings of E. dunnii did not increase water holding capacity in a linear form and the high proportion of bentonite did not improve seedling in the lower water regime, although the 5 % of bentonite gave a good results of seedlings growth, so the purpose of bentonite in the substrate to improve water holder capacity and minimize the irrigation would not be fully attended.
期刊介绍:
Forest Ecology and Management publishes scientific articles linking forest ecology with forest management, focusing on the application of biological, ecological and social knowledge to the management and conservation of plantations and natural forests. The scope of the journal includes all forest ecosystems of the world.
A peer-review process ensures the quality and international interest of the manuscripts accepted for publication. The journal encourages communication between scientists in disparate fields who share a common interest in ecology and forest management, bridging the gap between research workers and forest managers.
We encourage submission of papers that will have the strongest interest and value to the Journal''s international readership. Some key features of papers with strong interest include:
1. Clear connections between the ecology and management of forests;
2. Novel ideas or approaches to important challenges in forest ecology and management;
3. Studies that address a population of interest beyond the scale of single research sites, Three key points in the design of forest experiments, Forest Ecology and Management 255 (2008) 2022-2023);
4. Review Articles on timely, important topics. Authors are welcome to contact one of the editors to discuss the suitability of a potential review manuscript.
The Journal encourages proposals for special issues examining important areas of forest ecology and management. Potential guest editors should contact any of the Editors to begin discussions about topics, potential papers, and other details.
