Soil seed bank - Wikipedia
The soil seed bank is the natural storage of seeds, often dormant, within the soil of most ecosystems. [1] The study of soil seed banks started in 1859 when Charles Darwin observed the emergence of seedlings using soil samples from the bottom of a lake.
Soil seed bank | Definition, Ecology, Types, Importance, & Examples ...
A soil seed bank is the natural storage of seeds in or on the soil of many ecosystems, which serves as a repository for subsequent generations of plants. Given the variety of stresses that ecosystems experience, soil seed banks are often a crucial survival mechanism for many plants.
A global database of soil seed bank richness, density, and …
2024年10月2日 · A soil seed bank is the collective name for viable seeds that are stored naturally in the soil. At the species or population level, the ability to form a seed bank represents a strategy for (re)colonization following a disturbance or other change in the local environmental conditions.
Soil seed bank responses to anthropogenic disturbances and its ...
2023年10月1日 · Soil seed banks can serve as a direct source of natural restoration, as well as a buffer against environmental changes in vulnerable ecosystem. However, in arid mining area, it remains unclear how the anthropogenic disturbances affect the seed banks and what its potential for vegetation restoration.
Soil Seed Bank Dynamics: History and Ecological Significance …
2013年1月1日 · A soil seed bank, which begins at dispersal and ends with the germination or death of the seed (Walck et al. 2005), is a reserve of mature viable seeds located on the soil surface or buried in the soil (Roberts 1981) that provides a memory of past vegetation and represents the structure of future populations (Fisher et al. 2009).
Soil Seed Bank - an overview | ScienceDirect Topics
Soil seed bank: the viable seeds present on or in the soil, including both those that germinate within a year of initial dispersal (the transient component) and those that remain in the soil for longer periods (the persistent component).
Responses of soil seed banks to drought on a global scale
2023年3月15日 · Soil seed banks (SSBs) are reservoir or collections of viable seeds in the soil. SSBs are capable of replacing adult plants under certain favorable conditions (Mmusi et al., 2021), which is one of the most important functional parts of …
Vertical distribution of soil seed bank and the ecological …
Soil seed banks play a central role in vegetation dynamics and may be an important source of ecological restoration. However, the vast majority of seed bank studies examined only the uppermost soil layers (0–10 cm); hence, our knowledge on the depth distribution of seed bank and the ecological significance of deeply buried seeds is limited.
Investigating the Soil Seed Bank – awkward botany
2019年5月1日 · Outside of human-built seed banks, many plants maintain their own seed banks in the soil where they grow. This is the soil seed bank, a term that refers to either a collection of seeds from numerous plant species or, simply, the seeds of a single species. All seed bearing plants pass through a period as a seed waiting for the chance to germinate.
The Soil Seed Bank: Plant Communities’ Secret Weapon
2023年11月8日 · Plant communities have a secret survival tool buried underground: the soil seed bank. The soil seed bank is made up of all the seeds of any plant species buried in the soil in an area. They build up over the years as plants drop seeds which lie dormant, sometimes for many years, until they germinate and grow up into a new plant.
