A study was conducted to establish and screen various genotypes of Jatropha curcas, preinoculated with selected arbuscular mycorrhizal fungi (AMF) using fly ash as the medium in the nursery. J. curcas was collected from Sehore, Beed/Kollar, Khandwa, Shahdol, Jhabua and Khargone in Madhya Pradesh, Jagdalpur in Chattisgarh, Badi Sadari, Udaipur in Rajasthan and Kanchivaram in Tamil Nadu, India. Four different types of AM inocula: Glomus intraradices, Glomus sp 1, Glomus sp 2 and Glomus sp (mixture of all three) were prepared. Results revealed that irrespective of germplasm collected from various provinces, mycorrhizal inoculation produced significantly higher dry biomass (shoot + root) per plant compared to uninoculated plants. The plants (irrespective of province) inoculated with Glomus sp 1 and mixed species of AMF showed higher biomass when compared to other AM types. Irrespective of AM type inoculation, the province that performed best in terms of producing higher biomass was found to be Shahdol, Madhya Pradesh. ANOVA results revealed that mycorrhizal plants had significantly higher P content in plant tissues compared to uninoculated plants. Plants from Shahdol, Madhya Pradesh recorded higher P content. The main effects of AMF and provinces and their interaction on heavy metal profile of a particular metal were varied. The interaction was significant for aluminium, lead and zinc, while non-significant for manganese accumulation.. |
