| 摘 要： | 在盆栽条件下,以柑橘砧木枳（Fructus aurantii）幼苗为试验材料,在基质中接种从广西土壤中分离得到的不同丛枝菌根（AM）真菌菌株,探讨不同AM真菌对枳根系的侵染能力和植株生长的影响。结果表明：用于试验的14个AM真菌菌株均能与枳根系形成共生关系,平均侵染率为36.16%,其中侵染率最高的菌株是黄雷德克囊霉（Redeckera fulvum, Rf）,侵染率高达92.83%,侵染率最低的菌株是副冠球囊霉（Glomus coronatum, Gc）,侵染率仅为0.23%;接种黄雷德克囊霉、摩西斗管囊霉（Funneliformis mosseae, Fm2）和副冠球囊霉这3个菌株处理的枳植株的株高、茎粗、叶片数和叶柄长均高于CK,是枳的优势菌株,能促进枳的生长。

| Abstract: | Bitter orange (Fructus aurantii) is commonly used as the rootstock for citrus. In this experiment, the arbuscular mycorrhizal fungi isolated from Guangxi soil were inoculated into the potting mix where bitter orange seedlings were grown, and the growth characteristics of mycorrhizal and non-mycorrhizal plants were compared. The data showed that all 14 arbuscular mycorrhizal fungi strains employed in the experiment could form symbiotic relationship with the root system of F. aurantii. The overall average infection rate was 36.16%, with Redeckera fulvum having the highest infection rate (92.83%). Glomus coronatum exhibited the lowest infection rate (0.23%). Redeckera fulvum, Glomus mosseae, and Glomus coronatum significantly increased plant height, stem diameter, leaf number, and petiole length of F. aurantii seedlings, when compared to the mock inoculation control group. The study demonstrates that the inoculation of the arbuscular mycorrhizal fungi could significantly promote the growth of bitter orange plants. |
