In subtropical Hawaii where suckers develop along with the fruits, the costs of propagule production with chlorflurenol were kept low by forcing flowering of shoots that would normally produce a ratoon crop, A few days after forcing the shoots were sprayed with a chlorflurenol solution to initiate propagule production (D.
The role of propagule pressure in explaining species invasions.
Unless new genetic material is introduced to the population by pollen or propagule dispersal, the genetic diversity of small populations will eventually be reduced impacting the species capacity to adapt to a changing environment (WEEKS et al., 2011).
The IV inoculum was more effective than PS and CR inocula for promoting plant growth and colonization in both species, suggesting that the number of infective propagule in the inoculum should be considered for better effects.
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., 2010; FRAGOSO et al., 2015).
Sediment samples were collected at random from three locations in the rhizosphere of each propagule. These sediment samples were collected using a stainless steel spoons and were immediately placed in a separate clean glass pot.
"These findings add to the growing evidence that commerce is a good indicator of what we call 'propagule pressure'--the number of individual organisms being introduced in a new area," Shoemaker says.
This will in turn allow resource managers take appropriate measures to maximize propagule survival during reforestation efforts.
