摘　　要：温室条件下,研究不同补光光源对丛枝菌根(A rbuscu lar m ycorrh izae,AM)真菌G lom us m osseae生长发育的影响。结果表明:不同补光光源的光谱不同,对菌根共生体生长发育的影响不同,以农艺钠灯作为补光光源处理的宿主植物的光合速率及可溶性糖含量高于其它两种光源处理,综合比较菌根长度、根外菌丝量及孢子数三项指标,以农艺钠灯作为补充光源对真菌G.m osseae的生长发育最为有利。金属卤灯、荧光灯两处理宿主植物中氮、磷浓度高于农艺钠灯处理,可能对菌根真菌的生长发育有不利影响。因此,工厂化AM菌剂生产中,如果需要补充光照,应以农艺钠灯作为补光光源。Under greenhouse conditions, the influences of three different lamps （metal halide lamp, fluorescent lamp and sodium lamp） on the growth of arbuscular mycorrhizal fungus Glomus mosseae were studied. The results showed that different supplementary lighting source with different spectrum influence the development of host plant-fungal isolate combinations differently. The level of photosynthesis of host plants and the concentration of soluble sugar in host plants under the sodium lamp treatment were higher than those under other tow treatments. By comparison of total length of external hyphae, colonized root length and spore numbers, the sodium lamp was found to be the best supplementary lamp for mycorrhizal development among the three supplementary lamps. The concentrations of N and P in host plants under metal halide lamp and fluorescent lamp treatments were higher than that under the sodium lamp treatment. It might influence the development of arbuscular mycorrhizal fungi adversely. So, when AM fungal inoculum is produced on a factory scale, if supplementary lighting source is needed, the sodium lamp is the best choice.
