Rhizospheric effect of vesicular arbuscular mycorrhizal inoculation on biomass production of Ruta graveolens L.: A potential medicinal and aromatic herb

A bio-inoculation experiment was performed on Ruta graveolens L., known as “Garden Rue” seedlings for the biomass production. Seedlings were inoculated with single and in combined mycorrhizal treatments. All inoculated seedlings showed significant biomass production than control seedlings. The phosphorus (P) content was more in seedlings inoculated with consortium of three native VAM fungi followed by Glomus mosseae, Acaulospora laevis and Gigaspora gigantea alone treatments. The control seedlings had the least P content but root P content was more than shoot P content in all treatments. The biomass of shoot and root was also significantly more in seedlings inoculated with consortium followed by G. mosseae, A. laevis and G. gigantea alone treatment. The control seedlings again had low shoot and root biomass. The Biovolume index (Bi) was also high in all inoculated treatments than non-inoculated control but consortium treatment (7.98) had at par Bi than rest of inoculation treatments. The quality index (Qi) value was also high in mixed consortium (1.42) and A. laevis treatment (1.42) each respectively than G. mosseae (1.38) and G. gigantea (1.29) treatments. Control seedlings had low value of Qi (1.27). The present study indicates that G. mosseae, A. laevis, G. gigantea are the best strains of VAM symbionts when mixed together for inoculating the R. graveolens to get higher yield of biomass. A. laevis is also good strain of VAM fungi for the same purpose. The G. gigantea alone proved least effective strain for inoculation purpose in R. graveolens but when mixed together in consortium of native VAM fungi as described above executed good results for enhancing the biomass production.

Some New Records of Stinkhorns (Phallaceae) from Hollongapar Gibbon Wildlife Sanctuary, Assam, India

This research paper represents for the first time an updated list of stinkhorn family, Phallaceae, in Hollongapar Gibbon Wildlife Sanctuary, Jorhat, Assam, India. There are seven species of stinkhorns naturally present in the study area. A description of all the species is given along with images of fruiting bodies of the fungi and their microstructures; information on the ecology and general distribution and data on the literature have been documented. The seven species of stinkhorns were found in and around area of the sanctuary which include Phallus indusiatus, Phallus duplicatus, Phallus cinnabarinus, Phallus merulinus, Phallus atrovolvatus, Mutinus bambusinus, and Clathrus delicatus.
