Abstract

Despite numerous studies on arbuscular mycorrhizal fungi (AMF) in potato (Solanum tuberosum L.), nothing is known about colonization by dark septate endophytes (DSE). In a study of DSE and AMF associations in a potato field at Meghalaya, northeast India, monthly DSE and AMF colonization ranged from 7.9±2.9–13.2±1.65 and 6.98±3.13–12.4±3.53%, respectively. There were no significant differences in monthly DSE and AMF colonization. AMF hyphal colonization had a significant negative correlation with pH and available phosphorus (p < 0.05). Total AMF colonization was negatively correlated with organic carbon (p < 0.05). DSE colonization showed a significant negative correlation with root hair density (p < 0.05). However, AMF colonization, although negatively correlated with root hairs, was not significant. Sixteen AMF morphotypes were identified from the genera Acaulospora, Gigaspora, Glomus, Pacispora and Scutellospora; a few remain unidentified. The results indicated that DSE and AMF colonization progressed synchronously with the dominance of Glomus tortuosum, Pacispora boliviana and Gigaspora margarita.
