摘要
以赣南早脐橙、红肉脐橙和纽荷尔脐橙3 个品种脐橙的根际土壤为研究对象,研究不同品种脐橙根际土壤中丛枝菌根真菌(Arbuscular mycorrhizal fungi,AM真菌)群落特征.结果表明:脐橙品种显著影响根际土壤中AM真菌群落α多样性,纽荷尔脐橙根际土壤中的OTU数和ACE指数均显著低于赣南早脐橙和红肉脐橙(P＜0.05);在各个菌属中,赣南早脐橙根际土壤中类球囊霉(Paraglomus)的相对丰度显著高于红肉脐橙和纽荷尔脐橙(P＜0.05).冗余分析(RDA)表明,土壤因子中,碱解氮显著影响脐橙根际土壤中AM真菌群落α多样性(F =7.8,P = 0.034),速效钾显著影响脐橙根际土壤中AM真菌群落结构(F =2.7,P =0.008).
Abstract
The community structures and diversities of arbuscular mycorrhizal(AM)fungi in rhizospheric soil of three navel orange varieties(Citrus sinensis Osbeck cv.GannanZao,Citrus sinensis Osbeck cv.Cara and Citrus sinensis Osbeck cv.Ne-whall)were investigated and compared with Illumina MiSeq high-throughput sequencing technology.The results show that navel orange varieties significantly affected the community α diversity of AM fungi in the rhizospheric soil rather than AM fungal community structure.The OTUs number and the ACE index in rhizospheric soil of navel orange Newhall were signifi-cantly lower than those in rhizospheric soil of navel orange Gannan Zao and Cara(P＜0.05).Among the genera,the rela-tive abundance of Paraglomus in rhizospheric soil of navel orange Gannan Zao was significantly higher than that in rhizos-pheric soil of navel orange Newhall and Cara(P＜0.05).Redundancy analysis(RDA)shows that alkali-hydrolyzale nitro-gen significantly affected the community α diversity of AM fungi in rhizospheric soil of navel orange(F =7.8,P =0.034),while available potassium significantly affected AM fungal community structure(F =2.7,P =0.008).
