Association of Glomus Intraradices in Sorghum Bicolor

Arbuscular mycorrhizae (AM) are beneficial symbionts for plant growth. They are associated with higher plants by a symbiotic association, and benefit plants in uptake of phosphorus nutrients, production of growth hormones, increase of proteins, lipids and sugars levels, helps in heavy metal binding, salinity tolerance, disease resistance, and even in the uptake of radionuclides. Mycorrhizal genes are also applicable in improvement of crop plants, due to their delivery into plants, by a process called, particle bombardment. The influence of Glomus intraradices inoculation on growth performance of Sorghum bicolour in three different potting material such as Vermicompost, soil: sand and coir pith compost was studied in a screen house experiment. The results obtained indicated the dependence of Sorghum bicolor on mycorrhizal symbiosis. Inoculation with vesicular-arbuscular mycorrhiza in vermicompost significantly improved the growth performance of Sorghum bicolor by showing significant increase in shoot and root length. Vesicular arbuscular mycorrhiza inoculation has a high potential in agroforestry as a bio-fertilizer.
