Effects of fragment size and water depth on performance of stem fragments of the invasive, amphibious, clonal plant Ipomoea aquatica

Burial depth and diameter of the rhizome fragments affect the regenerative capacity of a clonal shrub

“…Larger stolon or rhizome sizes may also positively affect the amount of resources stored in the stolons or rhizomes, and in turn increase survival and regrowth after clone fragmentation (Huber et al, 2014). Larger fragments therefore tend to grow better than smaller ones (Lin et al, 2012), because larger fragments are able to build more carbohydrate reserves than smaller ones can. The regenerative capacity of root fragments also increases with enlargement of fragment size (West et al, 2012).…”

“…In this study, therefore, we selected a typical rhizomatous perennial shrub to study the effects of fragment size and burial depth on the regenerative capacity of clonal shrubs. Disturbances of different intensities can yield clonal fragments of different sizes , and the size of fragments is an obvious and likely factor in their performance (Lin et al, 2012). The size of clonal fragments, however, is genetically determined and varies among species (Liu et al, 2007).…”

Effects of Age, Length, and Pattern of Burial on Survival of Mikania micrantha Stem Sections

“…One of the functions of the stem internode is to store energy reserves that may then be translocated to other parts of the stem section for regrowth (Baur-Höch et al 1990, Corre et al 1996, Volenec et al 1996, Stuefer and Huber 1999, Lin et al 2012.…”

“…This study revealed that cutting the M. micrantha stems into smaller sections (<3 cm) and burying them at depths of 10 cm or greater would improve the overall management of M. micrantha in crop and noncrop systems. et al 2010b, Dong et al 2012, Lin et al 2012, Song et al 2013. Physical or mechanical control methods of stoloniferous plants do not necessarily destroy all unwanted material, because tilling and / or slashing have the potential to slice and inadvertently spread and transplant vegetative material (Mann and Cavers 1979, Heap 1997, Johnson et al 2003, Chicouene 2007.…”

Vegetative Regeneration Capacities of Five Ornamental Plant Invaders After Shredding

“…However, despite the number of ornamental plant invaders found along roads and railways, as well as in other places commonly managed by mowing and shredding, little is known about the vegetative regeneration capacity of shredded invasive plant material, and the risk it represents for the environment (but see De Waal 2001;Song et al 2013). Rhizomatous and/or woody ornamental plants often show good vegetative reproduction (Davies et al 1994).The vegetative fragment size and the cutting period may have considerable impact on vegetative regeneration capacity (De Waal 2001;Cordazzo and Davy 1999;Weber 2011;Lin et al 2012). In the present study, we focused on five ornamental widespread invaders in Western Europe that are likely to be managed by cutting techniques (Levy et al 2011) (Randall and Marinelli 1996).…”
