We studied effects of season and soil treatments (watering, acidification, liming and combinations of these treatments) on soluble carbohydrates of mycorrhizal roots of Norway spruce (Picea abies (L.) Karst.). Arabinose, arabitol, fructose, glucose, inositol, lactose, mannitol, pinite, quinate, raffinose, shikimate, stachyose and trehalose were identified by HPLC. Concentrations of inositol, lactose and pinite were constant throughout the year, whereas concentrations of raffinose, stachyose and trehalose were higher in winter than in summer, and concentrations of glucose, fructose and mannitol increased from February to September. Soil acidification and liming had no effect on the annual mean concentrations of fructose, glucose, lactose, pinite, raffinose and stachyose. Liming increased quinate concentrations and decreased arabitol concentrations. Annual mean concentrations of arabinose and mannitol decreased in response to soil acidification. Annual mean concentrations of inositol increased in response to irrigation. None of the soil treatments affected the mean annual concentration of trehalose.
我们研究了季节和土壤处理（浇水、酸化、石灰处理以及这些处理的组合）对挪威云杉（Picea abies (L.) Karst.）菌根根中可溶性碳水化合物的影响。通过高效液相色谱法鉴定出了阿拉伯糖、阿糖醇、果糖、葡萄糖、肌醇、乳糖、甘露醇、松醇、奎尼酸、棉子糖、莽草酸、水苏糖和海藻糖。肌醇、乳糖和松醇的浓度全年恒定，而棉子糖、水苏糖和海藻糖的浓度在冬季高于夏季，葡萄糖、果糖和甘露醇的浓度从2月到9月增加。土壤酸化和石灰处理对果糖、葡萄糖、乳糖、松醇、棉子糖和水苏糖的年平均浓度没有影响。石灰处理增加了奎尼酸的浓度，降低了阿糖醇的浓度。土壤酸化导致阿拉伯糖和甘露醇的年平均浓度降低。灌溉使肌醇的年平均浓度增加。没有一种土壤处理影响海藻糖的年平均浓度。
