| 中文摘要: |
| 本文以枳橙（Citrus sinensis (L.) Osbeck譸oncirus trifoliate (L.)）为试验材料，利用盆栽试验，研究不同pH条件下接种丛枝菌根(Arbuscular mycorrhiza)真菌摩西球囊霉(Glomus mosseae)对柑橘砧木枳橙苗的生长及植株光合效应的影响。试验选定3个pH范围（pH 5.5~6.5, 6.5~7.5, 7.5~8.5）和接种摩西球囊霉为试验因子，共设6个处理组合，以不同pH条件下未接种摩西球囊霉为对照。采用单株小区，随机区组排列，重复10次。结果表明，接种摩西球囊霉能有效地侵染枳橙植株，菌根侵染率65%以上。试验还发现，处理植株的菌根侵染率和株高、生物量干重均显著高于对照植株，同时，接种AM真菌显著增加了植株叶片叶绿素含量，并显著提高处理植株光合作用速率和蒸腾速率。研究结果表明，接种AM真菌增强了宿主植物对土壤酸碱度的适应性，在酸性和碱性土壤上均能显著提高柑橘的光合效应。 |

| In this paper, citrange(Citrus sinensis (L.) Osbeck譸oncirus trifoliate (L.))was used to study the effect of the arbuscular mycorrhizal (AM) fungus (Glomus mossease) on growth and photosynthesis in sand culture under different pH conditions. This study was conducted to use the pot experiment . The experiment was carried out at three pH levels(pH 5.5~6.5, 6.5~7.5, 7.5~8.5) and inoculated with Glomus mossease as test factors. The study had six treatment, all non-inoculated with Glomus mossease treatments were used as control, and randomly cultivated to six kinds of soils. A treatment plot was conducted with single plant and arranged in a randomized block design with 10 replications. The results indicated that inoculated Glomus mossease can effectively colonize citrange plants, mycorrhizal colonization rate was more than 65%. The test also found that treated plants’ colonization rate, plant height and biomass dry weight were significantly higher than control plants, while inoculation with AM fungi significantly increased the leaf chlorophyll content, and significantly improve the processing plant photosynthetic rate and transpiration rate. The results showed that inoculation with AM fungi enhance the adaptability of the host plant in acidic and alkaline soil, and can significantly improve citrus photosynthetic effect. |
