Examples
-
The seed or any form of planting material (generally termed propagule) is a basic requirement in all development programs, i.e., agricultural crop production, agroforestry, plantation and reforestation projects.
Chapter 6 1992
-
(A propagule is any part of a plant that can separate from the parent and grow into a new plant, for example, a seed, an agave aerial plantlet, a cholla joint.)
-
Second, such reductions are very likely to happen more rapidly where the northward migration of boreal or temperate species is not limited either by habitat availability or propagule (dispersal stage of a plant or animal, such as fertilized eggs, larvae, or seeds) dispersal.

Beyond the ability to determine variation and infer propagule pressure, genetic tools can be used to detect, identify, and monitor invasive species.
-
This acceleration is likely because of a rise in propagule pressure, the number of individuals released in a particular area, and human disturbance to aquatic systems.
-
It is somewhat redundant in its wording, for an individual that disperses is a propagule and there is no need to specify that dispersal is to be between "populations".

-
Temporal dispersal takes place when dormant propagules of a species accumulate in its habitat, forming "propagule banks", and are activated at different times in the future.

Each propagate is made up of individuals derived from a single population, and there is no mixing of colonists from the different populations during propagule formation.
