Abstract

Culm cutting is very effective and convenient method for asexual propagation and even much less destructive than the other ways such as excavation of rhizomes. Despite that culm cutting is such a useful method, only few investigations for raising its efficiency have been carried out. We tried to examine the effect of different geographical populations and cutting sections on the shoot emergence, biomass production and its allocation in terms of cutting efficiency. Culms were sampled from three environmentally distinct wetlands : riparian marsh, salt marsh and montane fen and then they were cut separately into four sections from the bottom to the top part. Both factors of different population and section affected the shoot emergence together. Middle parts on the culm always showed more shoot emergence irrespective of different population. On the other hand, first section from salt marsh and fourth section from the montane fen did not exhibit any shoot emergence. Significant difference in increase of shoot emergence between different sections during investigation period was confirmed only from salt marsh population. Not only different population but also appropriate cutting section should be considered together for better efficiency in cutting of reed culms.
