MYCORRHIZAL DEVELOPMENT IN EUCALYPTUS CAMALDULENSIS DEHNH

Effects of arbuscular mycorrhizal (AM) and ectomycorrhizal (EM) inoculation on mycorrhiza formation development in E. camaldulensis seedlings were assessed this study. Two experiments, the first with AM fungi second EM fungi, set up successively using vermiculite-peat (VP) as growth medium, 2.5 mg l-1, 5.0 10 l-1 20 phosphorus (P) Ingestad's nutrient solution each experiment. The experiment three inocula (including Glomus clarum Nicolson Schenck. (isolate BR148-1) Gigaspora rosea FL105-5) one from a trap culture Bangladeshi soil) resulted 30-50% colonisation; most colonisation was by G. BR148-1 highest at P (>50%). In similar five isolates Pisolithus tinctorius (Pers.) Coker Couch., only isolate K55 >15% which occurred (>25%) while other <1% colonisation. This study showed that tended to be colonised more readily arbuscular- than ecto-mycorrhizal initial period seedling growth. There indications species could become after 16 weeks glasshouse, but proper care should taken select appropriate compatible inoculants.
