  1. ArbuscularMycorrhiza (AM) Fungi as component of INM INTRODUCTION Root – fungus association is called Mycorrhiza. There are two types of Mycorrhizal fungal association viz. Ectomycorrhiza and Endomycorrhiza (AM). Mycorrhizal plants increase the surface area of the root system and absorb nutrients from soil especially phosphorus and micronutrients by huphae that goes beyond root zone to absorb nutrients. Almost 90 % of crop plants are mycorrhizal mostly of AM type. Therefore, AM association in crop plants plays significant role in enhancing nutrient mobilization towards root. End Previous Next

  2. ArbuscularMycorrhiza (AM) Fungi as component of INM INTRODUCTION Four general types of Mycorrhizal fungal association viz. AM symbiosis are an essential component to sustain soil quality, plant health and productivity. Ectomycorrhizae(ECM), Ericoid or ecto-endomycorrhizae , orchid and arbuscular mycorrhizae (AM) have been recognized. Mycorrhizal plants increase the surface area of the root system and absorb nutrients from soil especially phosphorus, zinc and micronutrients by hyphae that goes beyond root zone to absorb nutrients.

  3. ArbuscularMycorrhiza (AM) Fungi as component of INM Gigaspora Glomus Vesicles and Arbuscules Mycorrhiza is the symbiotic association between plant roots and fungal mycelia End Previous Next

  4. ArbuscularMycorrhiza (AM) Fungi as component of INM CHARACTERISTICS OF ARBUSCULAR MYCORRHIZA Mycorrhiza increase the surface area of the root Absorb nutrients from soil especially phosphorus and micronutrients through hyphae and mobilize into the host cell. Almost 90 % of crop plants are mycorrhizal mostly of arbuscular type (AM) Mycorrhiza possess vesicles and arbuscules. Mycorrhiza species are: Glomus, Gigaspora, Scutellospora, Acaulospora, EntrophosphoraandSclerocystis End Previous Next

  9. ArbuscularMycorrhiza (AM) Fungi as component of INM LET US SUM UP Mycorrhiza is an association of fungal mycelia with roots of higher plants and are of two types viz. Ectomycorrhiza and Endomycorrhiza (AM). Mycorrhizal plants increase the surface area of the root system and absorb nutrients from soil especially phosphorus and micronutrients by hyphae that goes beyond root zone to absorb nutrients. contd….

  10. ArbuscularMycorrhiza (AM) Fungi as component of INM LET US SUM UP contd…. The mycorrhizal association is one of the important phenomena for better establishment of crop plants especially under nutrient deficient soils. Almost 90 % of crop plants are mycorrhizal mostly of AM type. End Previous Next
