中文摘要 | 本研究係採用盆栽試驗,以彰化縣重金屬污染之農田土壤作為供試土壤,探討臺灣二葉松(Pinus taiwanensis)與青剛櫟(Cyclobalanopsis glauca )兩種樹種在接種彩色豆馬勃(Pisolithus tinctorius, Pt )形成菌根後對土壤復育之功效。供試土壤呈近中性之弱酸性,氮、磷、鈣含量均高於一般土壤,重金屬鎘與鋅之濃度已達環保署優先整治含量。由苗木存活率及形質生長顯示,Pt 與二葉松及青剛櫟苗木之菌根,具有抵抗重金屬之效應。根外菌絲及子實體能吸收較多之鎘、鋅,接種組之根部重金屬吸收量較對照組低,證實菌根菌之根外菌絲及子實體具有截留重金屬之能力。 |
英文摘要 | The purpose of this study was to examine the remediation effect of Pisolithus tinctorius (Pt) mycorrhizae on heavy metal contaminated soil. Two kinds of seedling species, Pinus taiwanensis and Cyclobalanopsis glauca, were inoculated with Pt and cultured in pots with the heavy-metal contaminated soil collected from Chang-Hua area. Results showed that the soils were weak acid and their contents of nitrogen, phosphorus and calcium were higher than normal soils. The Cd and Zn contents of the soils had already reached the criteria of remediation priority regulated by Environment Protection Agency. The extraradical mycelium and fruiting body could absorb more Cd and Zn than host plant did, and the accumulation of heavy metal in mycorrhizal roots were less than those in non- mycorrhizal roots. Hence, the extraradical mycelium and fruiting body of mycorrhizal fungi had the ability to hold heavy metals back and could sequestrate them in the roots. |
