Abstract

The response of Typha australis to stem cut at three different heights was studied for four weeks. This was carried out in the field between August and September 2003. Matured Typha australis naturally occuring along the stream within the Institute Integrated Fish Pond Complex, New Bussa were randomly selected. The shoots were cut at 10cm, 20cm, and 30cm, above the soil level. The responses of the plant were assessed. Plant cut at 10cm showed re-growth for one week and later died, while those cut at 20cm and 30cm showed re-growth through out the period of experiment. Result showed previous height between 10cm and 20cm is significant (P>0.05) between 10cm and 30cm height re-growth rates. But plant cut at 20cm and 30cm showed no significant (P>0.05), in height. The results show the susceptibility of Typha australis to stem cut at 10cm or below. Typha australis cut at 10cm above soil level are not likely to survival
