Rice encrusting with small‐seeded native species for reintroduction in agroecosystems: a case study in Lindernia procumbens
Seed coating is commonly applied in agricultural seed industry to alleviate biotic and edaphic barriers and improve seed germination, seedling emergence and establishment. Recently, this seed enhancement technology has been tested and applied to seeds of native species for ecological restoration and conservation. This work presents a novel application of seed coating for the reintroduction of species with dust‐like seeds that render direct seeding and cultivation unfeasible. Here we have used seed coating on Lindernia procumbens (Krocker) Philcox (Linderniaceae), a threatened annual species of paddy fields. Lindernia procumbens seeds were encrusted to the surface of rice seeds that acted as carrier to spread the species along rice sowing. We first tested how two selected concentrations of binder affected L. procumbens germination, then we investigated sowing depth (i.e. surface level—light, and buried—darkness) effect. Rice encrusting is a feasible and valuable tool for preserving threatened species with tiny seeds, since binder did not limit L. procumbens germination. Light increased L. procumbens seedlings emergence compared to buried conditions. Although L. procumbens emergence was limited in a paddy field trial, we promoted the formation of a soil seed bank for the species. As such, this should not discourage the possibility to reintroduce rare species with tiny seeds in agroecosystems. This pioneering technique can be extended to ecological restoration, where there is an urgent need for new seed‐based approaches and seed‐coating technologies to improve seedling establishment and restoration efficacy.
期刊介绍:
Restoration Ecology fosters the exchange of ideas among the many disciplines involved with ecological restoration. Addressing global concerns and communicating them to the international research community and restoration practitioners, the journal is at the forefront of a vital new direction in science, ecology, and policy. Original papers describe experimental, observational, and theoretical studies on terrestrial, marine, and freshwater systems, and are considered without taxonomic bias. Contributions span the natural sciences, including ecological and biological aspects, as well as the restoration of soil, air and water when set in an ecological context; and the social sciences, including cultural, philosophical, political, educational, economic and historical aspects. Edited by a distinguished panel, the journal continues to be a major conduit for researchers to publish their findings in the fight to not only halt ecological damage, but also to ultimately reverse it.
