Once a propagule is ready to root, its density changes so the elongated shape now floats vertically rather than horizontally.
12.
In most studies a direct relationship is observed, the higher the propagule pressure the higher the success of the invasion.
13.
In horticulture, a "'propagule "'is any plant material used for the purpose of plant propagation.
14.
Although the exact nature of the infectious propagule is unknown, the leading hypothesis is the basidiospore created through sexual or asexual reproduction.
15.
The whole idea of plants controlling the rate of passage of a propagule, like a seed, is a wonderful, open question.
16.
One type of propagule is the ungerminated spores, which must percolate through the soil beyond the reach of light in order to germinate.
17.
Once a propagule is ready to root, it will change its density so that the elongated shape now floats vertically rather than horizontally.
18.
After 3 to 6 months, when the propagule is mature, it drops into the water where it can then be transported great distances.
19.
Once germinated, the seedling grows and forms a propagule ( a seedling ready to go ), which can produce its own food via photosynthesis.

He measured three common species of mangroves in Panama, these species showed an intraspecific variation of propagule size, and were disposed to attacks from larval insects.
