However, the mini-cutting presents some advantages over cuttings, as size reduction of cuttings and increased shoots productivity per area, and youth use of propagules (DIAS et al.
This medium was added with a graduated cylinder to propagule rhizospheres once a month for six months.
It was reported that the ability of taro to emerge from the soil is affected by propagule size (Mabhaudhi et al.
Annual plants like Cannabis are designed to maximize propagule production, achieved in part by growing as large as possible within the limitations of the length of their season and the cultural conditions of their growth sites.
The role of propagule pressure in explaining species invasions.
In the rainy season, the areas in the initial stage of succession had a greater number of infective propagules than the in other areas (180 propagules [cm.
Despite the positive relationship between propagule pressure and invasion success, some successful species invasions, especially those of arthropods, can be initiated by a very small number of individuals (38).
Among these measures, the following can be mentioned: periodic measurements of fungal propagules in the air with aeromycological studies, rigorous cleaning with disinfectants and dust removal, routine equipment maintenance, humidity control, air filtration with high efficiency particle air filters, and use of laminar flow ventilation systems, among others.
A small north Greenland population of 32 wolves with low and infrequent reproduction (Marquard-Petersen 2008, 2009) further supports this conjecture by indicating low propagule pressure into eastern Greenland during most years.
