Description
Two metal-tolerant endophytes (Diaporthe miriciae LF9 and Trichoderma asperellum LF11) were studied in vitro for antifungal activities using dual culture assay. Both isolates inhibited Ganoderma boninense (GB) under metal and non-metal stress, with higher inhibition by T. asperellum LF11 than D. miriciae LF9. T. asperellum LF11 was unaffected by the metals, consistently inhibiting GB (100%) in both conditions. In contrast, inhibitory activities by D. miriciae LF9 was encouraged under metal (32.81–70.64%) compared to non-metal (14.07%) stress; higher in Cu2+ (70.64%) and Zn2+ (63.10%) than Pb2+ (51.79%) and Cd2+ (32.81%). These in vitro activities differed from in vivo findings. After 12 weeks, infected seedlings of oil palms inoculated with D. miriciae LF9 showed lower disease incidence (DI) in non-metal (33%) and multi-metal (67%) treated soils, thus suggesting enhanced tolerance of seedlings …
