Abstracts |
This study investigated the effect of arbuscular mycorrhizal fungi (AMF, Glomus fasciculatum) on Gmelina arborea in respect of morphological (shoot length, root length, fresh and dry weight, leaf area and percent root colonization), biochemical (chlorophyll and phosphorus content), and acid phosphatase and alkaline phosphatase activities under two different phosphate levels over non-inoculated plants. The experimental design consisted of six treatments having non-AM inoculated and AM inoculated Gmelina plants with three phosphate levels (KH2PO4: 0, 50 mg in 100 ml D. W. and 200 mg in 100 ml distilled water) per 3 kg of sterilized soil. Results revealed that plants inoculated with AMF have grown taller than the non-inoculated plants. Shoot and root length consequently increased in Gf+1P level as compared to C+1P after 45 and 75 days of AM inoculation. Plant fresh and dry weight of AM inoculated plants increased in all phosphate levels studied. Percent mycorrhizal colonization increased with an increase in phosphate level in early stages of colonization. There was a significant increase in percent root colonization during 45 and 75 days of Glomus fasciculatum inoculation. Total chlorophyll content consequently increased in AM inoculated plants than in non-AM inoculated control plants at low phosphate level (50 mg) after 45, 75 and 100 in days of inoculation. Acid phosphatase activity increased in roots of Gmelina with increasing levels of phosphate, but it was found to decrease in 100 days of AM activity in Gf+2P as well as C+2P treatment. Alkaline phosphatase increased significantly in C+1P and Gf+1P Gmelina plants, but decreased slowly in Gf+2P as well as C+2P level. |
