摘要

Despite the ecological importance of arbuscular mycorrhizal (AM) fungi in the growth and yield of fruit crops, little is known about the indigenous endorhizal symbionts in neglected wild edible fruit plants of subtropical biomes. Hence, we evaluated the diversity and abundance of the AM fungal communities in the rhizosphere soils, as well as colonization patterns of AM and dark septate endophytic (DSE) fungi in the roots of three fruit plant species viz. Antidesma bunius, Elaeagnus conferta and Phyllanthus acidus, collected from Manipur, Northeastern (NE) region of India. In this study, 29 AM species were isolated from both natural field as well as trap culture soils of selected fruit plants. All the examined fruit plants had dual root colonization of AM and DSE fungi and revealed Arum-Paris type AM morphology. The highest AMF root colonization (%RLTC) was recorded in P. acidus, while DSE fungi (%RLTDC) were most prevalent in A. bunius. A significant positive and negative correlation also existed among SD, some AM and DSE fungal variables and soil properties (P < 0.05). Furthermore, the current study is the first to report on the prevalence of AM and DSE fungal colonization in selected wild edible fruit plants growing in mountainous terrains, indicating the possibility of using them in the future for sustainable fruit production.
