Exempel på hur man kan använda PROPAGULE i en mening

• One type of propagule is the ungerminated spores, which must percolate through the soil beyond the reach of light in order to germinate.
• Rangeomorphs appear to have had an effective reproductive strategy, based on analysis of the distribution pattern of Fractofusus, which consisted of sending out a waterborne asexual propagule to a distant area, and then spreading rapidly from there, just as plants today spread by stolons or runners.
• Windborne ascospores or conidia are the primary inoculum (also known as the propagule) and can be dispersed over considerable distances.
• Heterospory evolved due to natural selection that favoured an increase in propagule size compared with the smaller spores of homosporous plants.
• The fungal propagule germinates, creates an appressorium, and generates a penetration peg which produces degradative enzymes that break down the cuticle.
• Expediting the production of inbred lines: Even if the final propagule for the farmers' fields is hybrid seed, not hybrid clones, the parents of exceptional F1 hybrids could be immediately clonally propagated if they were rhizomatous.
• This part of the life cycle consists of protonema (the preliminary stage where the propagule develops green thread-like filaments), the rhizoids (filaments growing beneath the bryophyte that help anchor the bryophyte to its substratum), the stem, the leaves, its reproductive structure (archegonium in female plants, antheridium in male plants), and the calyptra (a thin tissue that forms from the venter of an archegonium and protects the sporangium as it develops).
