In perhaps an ultimate departure from normal plant sexual reproduction, propagules of narcotic strains, generated by tissue culture, have been encapsulated to form "synthetic" or "artificial" seeds (Chandra et al.
The main aims of the current study were to clarify on the basis of field studies and a greenhouse experiment (i) whether the slow natural re-vegetation of abandoned extracted peatlands is affected mainly by the propagules arrival or by their germination and juvenile plant survival in unfavourable conditions, (ii) whether the areas of extracted peatlands located close to the forest have a higher potential for re-vegetation than the central parts of the peatlands, and (iii) whether the lack of nutrients influences the germination of the arriving propagules and the number of species and plants.

These included general reduction of damage due to flash flooding (including accelerated erosion of the stream channel), provision of high-quality forage for grazing by livestock, refugia for propagules of numerous native species of plants, and diverse habitats for wildlife.
In the wake of the 2004 tsunami, mangrove seeds, called propagules, became a much sought after commodity in Indonesia, selling for a few cents each, as countries began replanting the protective forests.

In general, the process of biofouling on a surface consist of four essential stages which begins with (i) macromolecular adsorption; (ii) bacterial colonization; (iii) surface fouling by diatoms and protozoans and (iv) establishment of unicellular and multicellular epibionts such as invertebrate larvae and algal propagules (Qian et al.
In van der Valk's (1981) model of freshwater wetland vegetation dynamics, two basic types of wetland species are recognized: (1) species with long-lived propagules that are in the wetland seedbank and can grow when suitable conditions occur, and (2) species with short-lived propagules that can only grow in the wetland if they reach it during a period when conditions are suitable for germination.
Generally, Vetiver grass propagules are available in bundles of rooted slips bearing 3-5 tillers each.
