Abstract:

Family Cyperaceae, members are commonly known as sedges. This family has ambiguity about mycorrhizal or non-mycorrhizal nature. So far, many sedges have been investigated globally for mycorrhizal occurrence interest. However, a sedge genus, Eleocharis has been not paid more attention for mycorrhizal investigations. Present work is the first attempt to evaluate mycorrhizal status in a recently discovered endemic sedge species: Eleocharis konkanensis Chandore, Borude, Kambale & S.R. Yadav which grows in a Lateritic rocky plateaus habitat. This study makes a new report on mycorrhization in an endemic sedge: E. konkanensis The roots of E. konkanensis from lateritic platue are microscopically examined for colonization of AMF. The study revealed that the roots of all the plants were colonized in the range of 21 - 98% by AM fungal components. Overall colonization percentage (OCp) in E. konkanensis is 56.55. Analysis of mychorrhizal roots suggests there is great variation found in occurrence intensity (OI) expression for vesicles (MCp50± 1.15), arbuscles (MCp21.43± 0.65p), and hyphae (MCp 98.21± 1.70). Besides, extraradical and intraradical spores of AMF have been recorded to roots. During present work, 12 AMF species belonging to four Glomeromycota families are recorded in association with E. konkanensis. These AMF species are viz., Aculospora dilatata, A. scrobiculata, A. spinosa., A. sporocarpa, Acaulospora spp, A. tuberculata; Diversispora epigaea; Scutellospora arenicola, Glomus albidum, G. ambisporum, G macrocarpum and Septoglomus constrictum. Thus, E. konkanensis is the first representative of genus Eleocharis ever studied by any Indian mycologist with reference to root colonization followed by spore's identification of AMF at species level. Till the present work, no data was available on AMF species of genus Eleocharis. Hence, E. konkanensis is proposed here as the first representative of genus Eleocharis ever studied by any mycologist. Based on the relative abundance and spore density the native AMF species of endemic E. konkanensis are viz., Diversispora epigaea, Aculospora dilatata and Aculospora scrobiculata. Finally, on the basis of in-depth analysis we propose that Eleocharis konkanensis an endemic sedge of Maharashtra is a new mycorrhizal plant to the science.
