| Abstract: | Extract Arbuscular mycorrhizae are symbiotic associations between plant roots and soil fungi that belong to the order Glomales. They enhance the uptake of phosphate and improve plant growth (Mos.se 1973). Those functions have not fully been utilized in Japan, where a large amount of phosphate fertilizer is usually applied, because arbuscular mycorrhizal colonisation in plant is inhibited by a large application of phosphate (Mosse 1973; Abbott et al. 1984; Tawaraya et al. 1985; Schubert and Hayman 1986; Thomson et al. 1986; Amijee et al. 1989). It is important to analyse the conditions for symbiotic association between fungi and host plant to use arbuscular mycorrhiza. |
