| dc.description.abstract | Shorea spp. are member of Dipterocarpaceae family. They are tropical rainforest plant which have high economic value due to high quality of their timber and non-timber products. Ectomycorrhizal fungi had been used as biofertilizer for Shorea spp. This research aimed to study the ectomycorrhizal root morphotypes, isolation and identification of ectomycorrhizal fungi associated with Shorea spp. Sixty ectomycorrhyzal root tip samples were taken from Shorea saminis (plot 1), Shorea palembanica (plot 2), and Shorea stenoptera (plot 3). The results showed that all plants associated with ectomycorrhiza, with percentage of roots colonization around 60%. The highest abundance of associated root was found at plot 2, followed by plot 3, and the lowest was found at plot 1. Data of root morphotype analysis indicated that there were 5 major of root tip morphotypes. There were brown irregular pinnate, black irregular pinnate, silver irregular pinnate, brown monopodial pinnate, and black monopodial pinnate. Brown irregular pinnate was the dominant root tips morphotypes with the frequency was 60.9%. A total of 15 different isolates were isolated from 3 ectomycorrhizal root tips morphotypes, e.g. brown irregular pinnate, black irregular pinnate, and brown monopodial pinnate. All of the isolates were mycelia sterilia. Some of the fungi had special mycelial characteristics by producing hyphal anastomosis and produce intensive branching mycelium. | en |
