Regenerated Shoot Number (Coppicing Ability) After Pruning at Different Height Levels in one Year Old <I>Eucalyptus</I> (Mysore-gum)

Abstract

A study was conducted to find out the magnitude of regenerated shoot production (coppicing ability) after pruning in Eucalyptus (Mysore-gum). Shoot prunings were grouped at four height classes. Number of shoots regenerated after pruning were counted on individual plant basis. An analysis of variance showed that the four groups of pruning levels produced significantly different number of shoots. As the pruning height-level increased gradually, the mean number of shoot production decreased along with a decrease in variation. Increase in mean and variation at the lower level was possibly due due to the increased root-system influence or the juvenility at that Jevel. The highest mean for shoot production was obtained at < 10 cm beight of pruning. It was concluded. That pruning of Eucalyptus (Mysore-gum) plants be made at less than 10 cm level to produce maximum number of shoots for the establishment of a hedge-garden from which large number of cuttings may be made available to produce rooted-cuttings in a mass-scale for clonal forestry purposes.
