The effects of three Arbuscular Mycorrhizal Fungi (AMF), Glomus versiforme, G. intraradices and G. etonicatum) and three irrigation intervals (7, 9 and 11 days) on growth of onion (Allium cepa L.) cv. Red Azar Shahr were studied under two soil conditions (sterilized and non-sterilized). The results indicated that, AMF colonization improved plant height, Leaf Area Index (LAI), total biomass, bulb dry mass and diameter, Harvest Index (HI) and chlorophyll content (p < 0.001). Bulbing occurred 10-15 days earlier in mycorrhizal plants. Irrigation interval decreased biomass, LAI, Leaf Area Ratio (LAR), bulb diameter and dry mass and chlorophyll content (b and total) at 11 day irrigation interval. In term of interaction, G. versiforme at 9 day and non-mycorrhizal plants at 11 day produced the greatest and the lowest LAI (8.56 vs. 1.57), respectively. Mycorrhizal onions in contrary to non-mycorrhizal ones produced more LAI and biomass in sterilized soil and inoculation with G. etonicatum and the non-mycorrhizal onions in sterilized soil had the highest and the lowest biomass, respectively.
研究了三种丛枝菌根真菌（AMF），即多样球囊霉、根内球囊霉和摩西球囊霉，以及三种灌溉间隔（7天、9天和11天）对洋葱（Allium cepa L.）品种红阿扎尔沙赫尔在两种土壤条件（灭菌和未灭菌）下生长的影响。结果表明，AMF定殖提高了株高、叶面积指数（LAI）、总生物量、鳞茎干质量和直径、收获指数（HI）以及叶绿素含量（p < 0.001）。菌根植物的鳞茎形成比非菌根植物早10 - 15天。灌溉间隔为11天时，生物量、LAI、叶面积比（LAR）、鳞茎直径和干质量以及叶绿素含量（b和总量）均下降。在交互作用方面，9天灌溉间隔下的多样球囊霉和11天灌溉间隔下的非菌根植物分别产生了最大和最小的LAI（8.56对1.57）。与非菌根洋葱相反，菌根洋葱在灭菌土壤中接种摩西球囊霉时产生了更多的LAI和生物量，而灭菌土壤中的非菌根洋葱分别具有最高和最低的生物量。
