The objectives of this study were to determine (1) if shoots with an apical tip have higher regeneration (growth of new shoots and rhizomes from allofragments) and colonisation (root attachment in sediment) abilities and higher relative growth rates (RGR) than shoots without an apical tip, and (2) if fragment size correlates with regeneration and colonisation abilities and with RGR of fragments. For all species, over 60{\%} of fragments regenerated new shoots and colonised. Apical shoots and larger fragments generally had higher regeneration and colonisation abilities and higher RGR.

N2 - Colonisation by stream plants occurs to a large extent from simple stem fragments. Allofragments are stem fragments formed by mechanical breakage. We studied regeneration, colonisation, and growth rates in four common stream plants: Elodea canadensis Michx., Myriophyllum spicatum L., Potamogeton perfoliatus L. and Ranunculus baudotii x pseudofluitans. The objectives of this study were to determine (1) if shoots with an apical tip have higher regeneration (growth of new shoots and rhizomes from allofragments) and colonisation (root attachment in sediment) abilities and higher relative growth rates (RGR) than shoots without an apical tip, and (2) if fragment size correlates with regeneration and colonisation abilities and with RGR of fragments. For all species, over 60% of fragments regenerated new shoots and colonised. Apical shoots and larger fragments generally had higher regeneration and colonisation abilities and higher RGR. Relative growth rate for E. canadensis and M. spicatum was between 0.06 and 0.09 d-1 whereas it was about half this rate for Ranunculus and P. perfoliatus (0.02-0.04 d-1).
