Towards the construction of a seed traits database for restoration of subtropical seasonally dry ecosystems: Effects of light, temperature and seed storage on germination
There is an increasing need to restore areas with native species, but there is scarce knowledge about their germination requirements. Understanding the conditions for producing a high number of germinated seeds and how long seeds can be stored while maintaining their viability, may determine the success of a restoration project. Here, we present a group of species from subtropical seasonally dry forests of Córdoba, and the main modulators of their germination, in order to improve restoration practices. In recently collected seeds of 36 species, we evaluated germination at four alternating temperatures (15/5, 20/10, 25/15 and 35/20 ºC) in light and darkness, to define the optimal germination conditions. Additionally, we determined the effect of different times of seed storage on germination. Twenty three species showed germination percentages higher than 60 % at least at one temperature. Temperature and light had an effect on germination of most species. Many species had optimal germination at 25/15 ºC (50 %), most were indifferent to light (84.6 %), germinated in an average of ten days (73.5 %), and maintained their germination capacity for at least a year after being stored (65 %). This work marks the beginning of the development of a database of seed traits for subtropical native species of various life forms, distinguished by being produced from experimental trials conducted for this purpose.
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.
