Initial growth of Shorea leprosula cuttings under the shade of Peronema canescens

Tolkamp G. W., . and A. Priadjati, . (2003) Initial growth of Shorea leprosula cuttings under the shade of Peronema canescens. [Proceedings Paper]

The objective of this project is to accelerate the reforestation of alang-alang Imperata cylindrica grassland with dipterocarp dominated vegetation by creating suitable conditions for dipterocarp species to be provided by indigenous pioneer species. The experiment started by planting Shorea leprosula cuttings among Peronema canescens trees. A randomized complete block design was used with four different shading classes open area semi-closed stand closed stand and semi-open area. After 18 months of planting differences between site conditions in survival rates of S. leprosula cuttings were not significant. The survivaI varied from 67 to 83. There was no mortality after 11 months of planting. Plans under moderate shading of P. canescens closed stand and in semi-open areas with some shading by secondary shrubs young shrubs; were significantly taller and bigger than those under light shading by pruned P. canescens trees semi-closed stand and in open areas. Within almost 3 years. S. leprosula trees in a closed stand and in a semi-open area reached a height of 281 to 283 cm and a diameter of 33 to 34 mm. whereas in the open area and under the semi-closed canopy of P. canescens they were only 165 to 193 cm tall and 22 to 27 mm in diameter.

Abstract

The objective of this project is to accelerate the reforestation of alang-alang Imperata cylindrica grassland with dipterocarp dominated vegetation by creating suitable conditions for dipterocarp species to be provided by indigenous pioneer species. The experiment started by planting Shorea leprosula cuttings among Peronema canescens trees. A randomized complete block design was used with four different shading classes open area semi-closed stand closed stand and semi-open area. After 18 months of planting differences between site conditions in survival rates of S. leprosula cuttings were not significant. The survivaI varied from 67 to 83. There was no mortality after 11 months of planting. Plans under moderate shading of P. canescens closed stand and in semi-open areas with some shading by secondary shrubs young shrubs; were significantly taller and bigger than those under light shading by pruned P. canescens trees semi-closed stand and in open areas. Within almost 3 years. S. leprosula trees in a closed stand and in a semi-open area reached a height of 281 to 283 cm and a diameter of 33 to 34 mm. whereas in the open area and under the semi-closed canopy of P. canescens they were only 165 to 193 cm tall and 22 to 27 mm in diameter.
