Ishinn VAM Gold (Vesicular Arbuscular Mycorrhiza) is the most abundant kind of mycorrhiza described as ‘a universal plant symbiosis’. Mycorrhizae are mutualistic associations or symbiosis between soil fungi and plant roots that colonise the cortical tissue of roots. The host plant receives mineral nutrients and water while the fungus obtains photosynthetically derived carbon compounds. Ishinn VAM Gold is an inert carrier-based product containing the Endo mycorrhizal spores with minimum 40-60 spores per gram. The development of isolation techniques, pioneering the mass production designed by the promoters resulted in making the Ishinn VAM Gold a great success.
All these genus multiplied in corn (maize) root system by in – vivo method under natural condition.
Benefits of Mycorrhizae:
1
Tremendous physical increase in absorbing surface of root system; includes both mycorrhizae and hyphae growing from mycorrhizae into soil.
2
More selective ion absorption and accumulation, especially phosphorus.
3
Solubilization of normally nonsoluble minerals and their constituents.
4
Increased longevity of feeder root function; mycorrhizal roots persist longer on root systems than do nonmycorrhizal roots.
5
Resistant to feeder root infections caused by pathogens, such as Phytophthora and Pythium spp., present in many forest and nursery soils. This benefit apparently applies only to ectomycorrhizae.
6
Increased tolerance to soil toxins (inorganic and organic), extremes of soil acidity, and high soil temperatures.
Vesicles
Fine roots possess root hairs. VAM do not significantly alter root morphology - thought to function as energy stores for use by the fungus when the supply of host metabolites is low.
Arbuscules
Highly branched haustorium-like structures extend through the host cell wall.Bidirectional transfer of metabolites and nutrients between the two mycorrhizal partners.
Short-Lived: remains alive only for a few days before disintegrating and being digested by the cells of the plant. In a healthy VAM mycorrhizal relationship there is a continuous sequence of development and disintegration of arbuscules.
