Plants which are intentionally grown in fields and gardens are called cultivated plants. All other plants which are not supposed to be there and grow unwanted, are called weeds.
Types 4. Causes 5. Effects. Meaning of Seed Dormancy: Dormancy is a delaying mechanism which prevents germination under conditions which might prove to be unsuitable for establishment. As long as the seed remains viable … Ecology: Examining the Relationships Between Living Things ... Between landscape ecology and global ecology, this is the study of large-scale ecological phenomena that cover multiple geographic locations but are not large enough to be considered global. An example of this is continent-wide impacts of effects of a large volcanic explosion.
Other reasons that weed populations change with time are found in the study of weed ecology, a relatively new area of emphasis in weed science. Understanding

Trials were performed to test the germination ecology of buried weed seeds as a function of physical soil conditions such as of burial depth, texture, and compaction. Indeed, these ecological conditions, due to the adopted agronomic practices, play a crucial role in modulating the seed bank germination dynamics.

Moreover, marestail is the first plant that Weed - Wikipedia In weed ecology some authorities speak of the relationship between "the three Ps": plant, place, perception. These have been very variously defined, but the weed traits listed by H.G. Baker are widely cited. Weeds have long been a concern, perhaps as long as humans have cultivated plants.

Many plants introduced into Australia in the last 200 years are now weeds. Weeds typically produce large numbers of seeds, assisting their spread. Weed-Population Dynamics - an overview | ScienceDirect Topics Weed Population Dynamics. The biology of annual weeds emphasizes reproduction. Seed production, dispersal, longevity, dormancy, and germination are important features of weed population dynamics (see WEEDS | Weed Seed Biology).
