A portion of a plant or fungus, such as a seed or spore, from which a new individual may develop.

[New Latin prōpāgulum, diminutive of Latin prōpāgō, shoot, from prōpāgāre, to propagate; see propagate.]


(ˈprɒpəˌɡjuːl) or


(Botany) a plant part, such as a bud, that becomes detached from the rest of the plant and grows into a new plant
[C20: from propag(ate) + -ule]


(ˈprɒp əˌgyul)

also pro•pag•u•lum

(proʊˈpæg yə ləm)

a structure, as a plant cutting, that is used for propagation.
[1855–60; < New Latin propāgulum, derivative of Latin propāgō shoot, runner; see propagate, -ule]

In this case, the addition of exogenous auxin generated a phytotoxic effect on the propagule, as has been observed for other species, and the concentration of IBA became harmful (NIENOW et al.
sativa, one can recognize a comparable domesticated syndrome of propagule characteristics in all strains of fiber hemp, oilseed hemp and narcotic hemp.
This will in turn allow resource managers take appropriate measures to maximize propagule survival during reforestation efforts.
Under the propagule pressure hypothesis a single introduction event of a few individuals will be less likely to lead to a biological invasion than multiple introduction events of numerous individuals.
Interestingly, this "alignment-of-fitness" requires a "bottleneck" or unicellular stage when the organism consists of just one cell-a spore, zygote, or uninucleate asexual propagule.
2003), this species presented very rapid infectivity, high propagule concentration and a great number of spores, regardless of soil conditions.
Results allow inferences about propagule pressure for introduction of tick-borne diseases and emphasize the large sample sizes required to estimate this pressure.
