Camphorate, in which the corn powder was best, while the yam powder and lactic acid were comparatively poorer. The utilization of nitrogen sources by A. camphorate was diverse. The organic nitrogen sources were better than inorganic ones. The best result was achieved when (NH4)2SO4 and wheat bran was co-added, but (NH4)2CO3 could be hardly used when added solely.

樟芝对碳源利用较广，其中以玉米粉效果最好，而对山芋粉和乳糖的利用较差；樟芝对氮源的利用具有差异性，其中对有机氮源的利用较无机氮源好，以硫酸铵＋麸皮复合培养效果最佳，而对碳酸铵几乎不利用。

Seeds were sprouted at 25 ℃.The root-tip with 0.5~1.0 cm length were cut and treated in 4 ℃ refrigerator for 24 hours, fixed for 1~1.5 hours with Carnoy's fixative, differentiated for 10-15 min with hydrochloric acid and Ethanol 95 %(1:1), pressed to section in carmine for staining. Them were observed under microscope, then the samples that differentiated well chosen, covered on frozen station with mountin Canada balsam, for micro-photographing, counting and measuring.
