Endophytic fungi (EPF) and arbuscular mycorrhizal fungi (AMF) symbioses can promote the growth and productivity of several types of plants. This work aimed to investigate the effect of co-inoculation of an EPF NMS1.5 and an AMF UDCN52867 g.5 on the growth and yields of sunchoke ( L.) compared to the effects of full-dose and half-dose chemical fertilizer (15-15-15) under field conditions. Several plant growth parameters of the co-inoculated plants were significantly higher than the other treatments. Remarkably, such an effect was relatively equal to that of the full-dose chemical fertilizers. Moreover, the co-inoculation of EPF and AMF significantly improved the tuber yield production, even better than the use of a chemical fertilizer. This is the first report to show that plant growth promoting effects of the co-inoculation of EPF and AMF were exceptionally greater than those of the chemical fertilizer. Therefore, our EPF and AMF could potentially be used as a biofertilizer for promoting the growth and yield of sunchoke in the fields.
内生真菌(EPF)与丛枝菌根真菌(AMF)的共生关系能够促进多种植物的生长和提高产量。本研究旨在调查在田间条件下,与全量和半量化肥(15-15-15)相比,内生真菌NMS1.5和丛枝菌根真菌UDCN52867 g.5共同接种对洋姜(Helianthus tuberosus L.)生长和产量的影响。共同接种的植株的几个植物生长参数显著高于其他处理。值得注意的是,这种效果与全量化肥的效果相当。此外,内生真菌和丛枝菌根真菌的共同接种显著提高了块茎产量,甚至优于化肥的使用。这是第一份表明内生真菌和丛枝菌根真菌共同接种对植物生长的促进作用异常大于化肥的报告。因此,我们的内生真菌和丛枝菌根真菌有可能用作生物肥料,以促进田间洋姜的生长和产量。
