Mycorrhizal mycelium was allowed to grow into a compartment from which roots were excluded. Ammonium or nitrate was supplied exclusively to the fungus and the respiration rate before and after nitrogen addition was measured. Mycelial respiration in the fungal compartment represented 11-29%, of total fungal and root respiration. The mycelium in the fungal compartment received 20-29% of shoot net assimilation, and 43-64%, of the carbon allocated to the mycelium was respired. The nitrogen-induced respiration increase ranged, in the fungal compartment, from 54 to 180%.
菌根菌丝体被允许生长到一个排除了根系的隔室中。仅向真菌供应铵或硝酸盐，并测量添加氮前后的呼吸速率。真菌隔室中的菌丝体呼吸占真菌和根系总呼吸的11%-29%。真菌隔室中的菌丝体接收了地上部净同化量的20%-29%，分配到菌丝体中的碳有43%-64%被呼吸消耗。在真菌隔室中，氮诱导的呼吸增加幅度为54%至180%。
