    Mycorrhiza of Plantation Crops
    (2007-02) Ramesh, C.R.; Rohini Iyer
    Studies on endomycorrhizae of cocount and some of the perennial tree spice mixed crops have been recently initiated at the Central Plantation Crops Research Institute, Kasaragod. Soil and roots have been examined and spore types isolated. Crops grown on unfertilised soil yielded more fungal population compared to those on fertilised soil. Younger roots harboured more mycorrhizae than older ones. However, sessile spores were more in the older roots.

    Root Infection and Population Density of VA Mycorrhizal Fungi in a Coconut Based Multistoreyed Cropping System
    (1982) Ramesh, C.R.
    Spores of vesicular-arbuscular (VA) mycorrhizal fungi were found in all the soil samples collected from the root zones of plants forming a coconut-based multistoreyed cropping system, namely coconut, cacao, cinnamon and black pepper. Their numbers ranged widely from plant to plant (8-420 spores/100 g soil) and varied remarkably from sample to sample of the same crop. Of the eight species found, Gigaspora gigan-tea, G. gilmorei, Glomus fasciculatus (clusters), and G. macrocarpa were most common, G. microcarpa and a flat unidentified spore type were less frequent, whereas Sclerocystis sp. and a white unidentified spore type ' were rare. Usually more than two VA species occurred at the root zone of each crop. Root samples of all the hosts showed extensive infection (80-98%) with internal and external hyphae, and characteristic vesicles and arbuscules.
