Abstract
The investigation was carried out to study the biochemical, histochemical
analysis of Piper nigrum L. and Sorghum bicolor (L.) Moench inoculated with
mycorrhiza from different crop management systems. Black pepper and sorghum
were inoculated with mycorrhiza from the organic soil, inorganic soil, natural soil,
control and Glomus fasciculatum. There were three experiments in which the first
experiment was on growth response of black pepper to the inoculation of
mycorrhiza from different crop management systems. In second experiment black
pepper and sorghum were inoculated with mycorrhiza from different crop
management systems and in third experiment sorghum was inoculated with
mycorrhiza from different crop management systems. Histochemical analysis of
these crop plants were carried out to study the difference in the accumulation of
the polysaccharides, proteins and nucleic acids in leaf tissues of control and
mycorrhiza inoculated plants. Plants inoculated with Glomus fasciculatum showed
highest rooting percentage, percent root colonization, phosphorus, potassium and
nitrogen content. Plants inoculated with Glomus fasciculatum recorded increased
biomass than control. A significant difference in the accumulation of
polysaccharides, proteins and nucleic acid content was observed in leaf sample of
the plant inoculated with Glomus fasciculatum.
