Title ARBUSCULAR MYCORRHIZAL SPORE DENSITY AND ROOT INFECTION IN SOME WEEDS OF ASTERACEAE
AuthorsTabassum Yaseen, Muhammad Imran and Muhammad Shakeel
Abstract

The rhizospheric soil containing roots samples of two plants of the same family were collected from the three different locations of Tehsil Charsadda to find out the spore density, spore dominancy, relative abundance, evenness of the spore and the root infections. Three types of spores were found during the study i.e. Glomus (43.64%), Sclerocystis (29.55%) and Acaulospora (26.81%) of the total spores in both Parthenium hysterophorus L. and Conyza canadensis L. The spore density ranges from 75 to 93 spores per 100gm-1. The root colonization ranged from 15.12% to 34.48% in both plants. The highest spore density was recorded in P. hysterophorus while lowest in C. canadensis. Glomus formed highest community about 48.24% and 38.98% in both P. hysterophorus and C. canadensis respectively. The values of relative abundance, specie evenness Sampson index of dominancy and spore density revealed that the community is formed by the Glomus spores followed by Sclerocystis and Acaulospora. In case of root colonization, the most frequent infection was internal hyphal infection followed by the vesicular infection and external hyphal infection
