摘要：

Onion (Allium cepa) plants were grown in pots in two types of irradiated soil, mineral and organic. Onion development was observed under two or three levels of P fertilization, and three methods of arbuscular mycorrhizal fungus inoculation with two fungus species. In mineral soil, preinoculated onion plants had a higher biomass than non-inoculated control plants or plants inoculated with either colonized root segments or spores. Fungus species had no differential effect on dry biomass or final bulb diameter. Preinoculated onion plants reached marketable size (>25 mm bulb diameter) 2-3 weeks earlier than those inoculated by either of the other two methods. Non-inoculated onion plants remained stunted. Bulbs of onions inoculated with Glomus versiforme were firmer than those inoculated with G. intraradices. Increasing P fertilizer rates had a significant positive linear effect on the P tissue concentration of plants inoculated with G. intraradices or G. versiforme, but no effect on bulb firmness. The P tissue concentration of inoculated plants was significantly higher than that of non-inoculated controls, and in inoculated plants, it differed among inoculation methods. The P tissue concentration was higher in onion plants inoculated with G. versiforme than in those inoculated with G. intraradices. In organic soil, the dry biomass of preinoculated plants was higher than that of plants inoculated by root segments. The highest root colonization levels were obtained under a low soil P level with G. intraradices, and with the root segment method of inoculation with G. versiforme.
