| Summary: | ABSTRACT
This research was conducted to observe the effect of light intensity, mycorrhiza and dust charcoal. on the initial growth of Dryobalanops sp. Light intensity treatment was done by shading 60% of full light intensity (in Screen-house), whereas in Greenhouse light intensity is 100%. Mycorrhiza treatment was done by inoculating the seedlings with mycorrhiza spore suspension and dust charcoal treatment was done by mixing it to the soil media at 5%, 10% and 15% v/v while control soil media was only sterilized soil and sand with the ratio 3 : 1.
After 6 months, it was concluded that subtraction of light intensity had significant effect to height dan diameter . growth of Dryobalanops seedlings, whereas mycorrhiza inoculation had significant effect to diameter growth only. Dust charcoal treatment had significant effect only to height growth with the best effect at 10% volume ratio.
The result of soil analysis showed that soil media in Screenhouse (with lower light intensity) had higher Phosphate and Nitrogen contents than those in
Greenhouse. |
