“…40% greater than that from stem sections with one node (Song et al 2013). This suggests that longer stem sections with more than one node may contain more stored reserves than shorter ones (Suzuki and Stuefer 1999, Dong et al 2010a, Dong et al 2010b, Song et al 2013. The higher survival rate of M. micrantha stem sections with more than one node in our study is in general agreement with other studies undertaken on other vegetatively reproductive species such as S. (Stuefer and Huber 1999), peak downs curse (Polymeria longifolia Lindl.)…”

“…The growth (in terms of number of new ramets and mean biomass per plant) of floating plants with large stem bases was greater than of plants with small stem bases. Dong et al (2010) also found that the survival and growth of ramets of the invasive plant Alternanthera philoxeroides increased with the length of connected stolons after fragmentation. Although we did not measure the mobilization of carbohydrates and nitrogen in E. crassipes, we found that the stem bases were dramatically depleted, especially large stem bases.…”

“…Moreover, organic reserves in plant tissue are critical for winter stress tolerance and rapid regrowth (Volenec et al 1996). Storage organs, such as stolons and stem bases, can store soluble carbohydrates and proteins that can be retranslocated among inter connected ramets to improve the survival and growth of clonal plants under natural disturbances and environmental stresses (Madsen et al 1993, Stuefer & Huber 1999, Dong et al 2010. Therefore, greater stored resources contained in larger storage organs can be retranslocated to attached ramets and may facilitate the biomass accumulation and production of new ramets (Danckwerts & Gordon 1989, Baur-Höch et al 1990, Stuefer & Huber 1999.…”

The distribution of the invasive aquatic plant Eichhornia crassipes is considered to be limited by winter survival. Therefore, winter warming, as well as characteristics of overwintering organs, are expected to affect its distribution and survival. An experiment was conducted to analyze the effects of winter warming and stem base treatments (size or burial) on winter survival, regrowth and thus performance of floating or rooted plants of E. crassipes using a simulated warming system in a greenhouse. Winter warming significantly increased the percentage survival in both forms of the plant and facilitated its regrowth and clonal propagation. Stem base size played an important role in determining survival, regrowth and vegetative propagation. Moreover, water cover and sediment burial of stem bases facilitated overwintering. After winter survival, a larger fraction of the biomass of E. crassipes was allocated to shoots. These results suggest that, with climate warming, the invasive ability of E. crassipes will be enhanced, with distribution spreading to the north into central and north China, favouring plants with large stem bases.

Therefore, greater stored resources contained in larger storage organs can be retranslocated to attached ramets and may facilitate the biomass accumulation and production of new ramets (Danckwerts & Gordon 1989, Baur-Höch et al. 1990, Stuefer & Huber 1999. Although sediment burial and storage organ size may contribute to winter survival and regrowth of plants during the overwintering period, their effects on overwintering of plants are still largely unknown, especially for invasive aquatic plants.Biomass allocation is a fundamental aspect of the competive ability of invasive aquatic plants, which often allocate a large fraction of their biomass to form canopy and to support the rapid spring growth that allows them to suppress other species (Madsen 1991, Sytsma & Anderson 1993. For instance, 2 invasive aquatic plants, water hyacinth Eichhornia crassipes and alligator weed Alternanthera philoxeroides, can form dense stands above the water surface that exclude almost all other species (Aston 1977, Julien & Bourne 1988. Villamagna & Murphy (2010) stated that greater allocation to shoots may enhance water hyacinth's ability to shade out other aquatic plants and algae in the water column. However, to our knowledge, little information exists on the effects of winter warming on the biomass allocation pattern of regrowth after winter survival for invasive aquatic plants.Eichhornia crassipes, originating from tropical South America, is a mat-forming aquatic plant with floating and rooted forms, and is one of the world's most preva...

“…Previous studies of the survival and growth of small clonal fragments have contrasted the probability of establishment of seeds and fragments of the same species (e.g., Going et al 2008) and found effects of such environmental factors as substratum, burial, and the orientation at which fragments lodge (Bimova et al 2003;Di Carlo et al 2005;Dong et al 2010a;Xie et al 2010). Although size of fragments is an obvious and likely factor, relatively few studies have explicitly tested its effects on survival or growth, and those that have reported different effects in different species (Cabaço et al 2005;Truscott et al 2006;Klimešová et al 2008).…”

Effects of fragmentation on the survival and growth of the invasive, clonal plant Alternanthera philoxeroides

The capacity of small clonal fragments to survive and grow is a major factor in the spread of clonal plants, especially aquatic species. This study of the introduced, invasive, amphibious, stoloniferous herb Alternanthera philoxeroides in China tested the effects of fragment size, of loss of the stolon apex, and of the original position of a fragment within a clone before fragmentation on the survival and growth of fragments in a greenhouse experiment. The stolon internodes of plants consisting of one stolon with 5 ramets were severed in all 16 possible patterns, generating fragments of 1-5 ramets. These 16 fragmentation treatments were crossed with removal of the stolon apex. Fragmentation and apex removal did not affect total growth of plants, but more highly fragmented plants produced smaller, more numerous ramets. The survival of fragments consisting of one original ramet was about 85%, compared to 100% survival of fragments with 5 original ramets. Fragments consisting of the youngest ramets along the original stolon grew more than fragments of the same size that consisted of older ramets. These effects of fragmentation on growth provide new evidence for clonal integration of the rate at which connected ramets produce new ramets and novel evidence that fragments produced from different portions of clones have different potential for spread. They further suggest that detachment of small groups of distal ramets along stolons in the field might be very effective in spreading the species and that a trade-off between the number and the size of new ramets produced by fragments may represent an adaptive, plastic response to disturbance. Results do not recommend intentional fragmentation of clones as a means of controlling the rate of growth of this invasive species but suggest that incidental fragmentation may not increase its growth in mass, although it may increase its rate of spread.
