Abstract

Microbiota are capable to interact with different types of trees, shrubs, and herbs thus play a key role in plants fertility productivity and sustainability. Arbuscular mycorrhizae fungi are beneficial microbiota which make the symbiotic association with plants. Previously, it was thought that symbiotic fungi facilitate plant growth. Thus, the current study was conducted to the comparative study between two stages of Triticum aestivum L., (fruiting and vegetative stage) of some farmland of District Charsadda. Our results indicated that Triticum aestivum L. form a mycorrhizal association in all fields, most significantly in the field of Behlola area, where the highest spore density was found due to the presence of high calcium and low magnesium. The most frequent species was found to be Glomus (48.91%) followed by Sclerocystis (28.42%) and Acaulospora (22.68%) in the vegetative, and fruiting stage (i.e. 39.87%, 33.21%, 26.92%) respectively. At vegetative stage Glomus, Sclerocystis, and Acaulospora revealed highest spore density of 53.38%, 34.51% and 25.00% in the fields of Tebana, Sarki and Behlola areas, respectively, and at fruiting stage high spore frequency such as 47.01%, 35.65%, and 31.04% was observed in fields of Sarki, Ghazgi and Shah No. 6, respectively. The percent of root colonization showed the infection ranging from 20-100. Maximum infection was recorded for the fruiting stage followed by a vegetative stage of the plant.
