1. MYCORRHIZA

2. Mycorrhiza Mutualistic symbiosis (non-pathogenic association) between soil-borne fungi and roots of plants. Greek: mykes (mushroom) and rhiza (root) (Frank, 1885) The plant nourishes the fungus : C The fungus nourishes the plant : water and soil nutrition (P, N, K, Ca, Zn, Mn, S, etc)

4. Role of Vesicular Arbuscular Mycorrhizal Fungi on Growth of Banana derived from tissue culture

5. Types of mycorrhiza Ectomycorrhiza The fungus grows intercellularly (never intracellularly) in the cortex of plant’s root (so called Hartig net) Endomikoriza The fungus grows inter- and intracellularly and forms specific fungal structures within the corcical cells. Ectendomycorrhiza Vesicular Arbuscular Mycorrhiza (Arbuscular Mycorrhiza) Arbutoid Mycorrhiza Monotropoid Mycorrhiza Ericoid Mycorrhiza Orchid Mycorrhiza

22. Function of mycorrhiza Increase nutrient uptake of plant from soil P nutrition and other elements: N, K, Ca, Mg, Zn, Cu, S, B, Mo, Fe, Mn, Cl Increase diversity of plant Produce uniform seedling Significant role in nutrient recycling More tolerant to adverse soil chemical constraints which limit crop production Increase plant resistance to diseases and drought Stimulate the growth of beneficial microorganisms Improve soil structure Stable soil aggregate – hyphal polysaccharides bind and aggregate soil particles

23. Function of mycorrhiza in Nutrient uptake Increase the soil volume explore for nutrient upatake Enhance the efficiency of nutrient absorption from the soil solution P concentration in the soil solution is very low in tropical soils the soil around the growing root is rapidlydepleted of P ions within a distance of few mm Soil P diffusion rate is extremely slow Mycorrhizal external mycelium grows far beyond P depletion zone Influence by soil fertility particularly P Determined by host dependency on mycorrhizal fungi Mycotrophic Obligate mycotrophic plant Facultative mycotrophic plant Non-mycotrophic Non-host:
