| 摘 要： | 研究了柞树林下菌根真菌对Ｃ、Ｎ营养的利用状况．结果表明，供试菌种对Ｃ源的利用较为广泛，葡萄糖、果糖为其最适碳源，平均生长量比对照高出４．４倍；供试菌种对有机氮的利用优于无机氮，平均生长量比无机氮源高出１．６倍，硝态无机氮源中平均生长量为对照的２．５倍，对铵态氮的利用较差，平均生长量仅为对照的２．２倍

| Abstract: | The results showed that the test fungi strains could utilize a broad kind of carbon sources, and glucose and fructose were the optimal. With C nutrition, the average growth of fungi was 4.4 times higher than the control. Organic nitrogen was more efficient than inorganic one, with an average growth of 1.6 times higher than the latter. With inorganic N sources, the strains grew faster on nitrate, with an average growth of 2.5 times higher than that of control, and utilized ammonium slightly poor only with an average growth of 2.2 times higher. |
