| Abstract | The Study on the effects of bolete (Phlebopus portentosus)on the growth promotion of Burmese rosewood (Pterocarpus macrocarpus Kurz.)by using different volume of P. portentosus inoculum. A Completely Randomized Design (CRD) consisting of seven treatments were done. The treatments were: control (no inoculation), inoculation with 10, 20 and 30 mL (0.3 mg/ml biomass) of P. portentosus inoculum, inoculated once or twice, with a 15-day interval between inoculations. Four-month-old P. macrocarpus seedlings were used. Growth parameters were recorded every 30 days for 180 days after inoculation. Data were analyzed using a statistical program. The result showed that inoculation twice with a volume of 20 ml P. portentosus gave the best results. It was found that the average quantities of chlorophyll A, chlorophyll B and total chlorophyll content measured by spectrophotometer were 2.41 ± 0.31, 1.20 ± 0.86 and 3.61 ± 0.55 mg/g, respectively. The quantities of chlorophyll A and total chlorophyll compared with control were increased by 167.78 and 67.91 percent, respectively. The results were significantly different from the control at the statistical level (p ≤ 0.05). The average stem height, diameter at root collar, canopy width, and total biomass were 54.59 ± 8.83 cm, 8.05 ± 1.02 mm, 36.35 ± 2.14 cm and 16.03 ± 2.42 g, respectively. The average stem height, diameter at root collar, canopy width, and total biomass compared with control were increased by 41.02, 42.98, 14.34 and 46.79 percent, respectively. The results were significantly different from the control at the statistical level (p ≤ 0.05). The P. portentosus hyphae attached to P. macrocarpus seedlings roots were examined by Scanning Electron Microscope (SEM) at 100 um. The result showed that the roots of the inoculated seedlings had hyphae attached to the surrounding root surface. The study results could be used as a guideline for promoting re-forestation by using mycorrhizal mushroom (P. Portentosus) along with economic trees to increasing plant growth. |
