Long-term Partitioning, Storage and Remobilization of 14C Assimilated by Trifolium repens (cv. Blanca)

How internode length, position and presence of leaves affect survival and growth of Alternanthera philoxeroides after fragmentation?

“…These results agree with previous findings on Potentilla anserina (Stuefer and Huber 1999) and suggest that storages in stolon internodes increase the fitness of juvenile ramets. By monitoring changes in carbohydrate and protein contents in stolon internodes, it has been shown that substantial amount of non-structural carbohydrates and soluble proteins stored in stolon internodes could be readily mobilized and used for the regrowth of damaged tissues (Danckwerts and Gordon 1989;Corre et al 1996;Baur-Höch et al 1999;Lawson et al 2000;Goulas et al 2001), and that at low temperature the Means ? 1 SE are given survival rate of the Eremochloa ophiruoides stolons was positively correlated with the carbohydrate content in stolon internodes (Fry 1993).…”

“…1 and 2), suggesting that storages in leaves contribute to the fitness of juvenile ramets and such effects do not depend on the amount of the reserves in the internodes of the ramets. There is evidence that leaves can store some non-structural carbohydrates and soluble proteins (Granstedt and Huffaker 1982;Danckwerts and Gordon 1989;Corre et al 1996), and these substances stored in the two opposite leaves may have been used by the ramets of A. philoxeroides to sustain its survival and growth. Therefore, in addition to the main function as a primary carbohydrate producer through photosynthesis, leaves may also serve as a short-term reserve that can be used by the ramets bearing them to deal with severe disturbance.…”

“…Besides the main function of photosynthesis, leaves can also store a certain amount of carbohydrates and proteins (Granstedt and Huffaker 1982;Danckwerts and Gordon 1989;Corre et al 1996). After fragmentation, storage in leaves may also contribute to the survival and growth of unrooted ramets, especially when the storage in other plant parts (e.g.…”

Overwintering survival and regrowth of the invasive plant Eichhornia crassipes are enhanced by experimental warming in winter

“…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.…”

“…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.
