Microorganisms In Plants

Microorganisms are most abundant members of the soil biota. The soil organisms that develop advantageous symbiotic relationships with plants roots and contribute to plant growth are called mycorrhizal fungi. The most common and superlative known of these associations are the Vesicular Arbuscular Mycorrhizae (VAM) fungi (Chandra and Kehri, 2006). Arbuscular mycorrhizal fungi comprise intra- and extraradical structures. In Glomeromycota, intraradical hyphae can penetrate the outer cell wall of root and grow between or inside of the root cell wall and plasma membrane where they expand the intraradical structures, arbuscules and vesicles. The extra radical structures are hyphae and spores that develop outside of the roots in the soil (Smith and

Wheat (Triticum aestivum) belongs to family Poaceae. Poaceae (formerly known as Gramineae) is often considered to be the most important of all plant families to human economies. The variety used was Raj-3077 hybrid wheat seed, because this variety of Wheat (Triticum aestivum) most commonly grown by the farmers in Jaipur region.

The earthen pots were taken and filled with air-dried sterilized soil (3-4 kg) collected from barren land. The root system of uniformly well infected sorghum seedlings together with the adhering soil were finely chopped and used as the starter inoculums. The pots were filled with air dried sterilized soil with 5-10 per cent of the VAM starter inoculums as a layer of one- two inches below the soil level and surface sterilized seeds of Wheat (Triticum aestivum) were planted (sowing).

Different treatments were maintained i.e., T0- Control (non-inoculated), T1- Glomus mosseae (single), T2- Glomus fasciculatum (single), T3- Gigaspora decipiens (single), T4- Glomus mosseae + Glomus fasciculatum, T5- Glomus mosseae + Gigaspora decipiens and T6- Glomus fasciculatum + Gigaspora decipiens. A set of control was also maintained in similar condition without any
