Microbiology Institute, Guangxi Academy of Agricultural Sciences, Nanning, Guangxi 530007, China Abstract: To provide fundamental references and better ways of preventing and controlling citrus Huanglongbing (HLB), a research was conducted to obtain arbuscular mycorrhizal (AM) fungi that possess plant growth-promoting and disease resistance abilities. The experiment utilized the pot culture method, where 17 strains of AM fungi were inoculated into the roots of Catharanthus roseus 　　　www.taodocs.com　　　　　　　　　　:　　　;　　　　　　;　　　　;　　　　　;　　　　　　　:S436.66 　　　　　:A Effects of Inhibition Citrus Huanglongbing on Catharanthus roseus with Different Arbuscular Mycorrhizal Fungi Species QUAN Dawan1, 4, LI Dong2, ZHANG Jinlian3, 4 *, SONG Juan4, HU Liu2, CHENG Tong3, HUANG Jinghua1 *, CHEN Tingsu4 1.

that were in the seedling stage. The colonization of different AM fungi strains were analyzed to understand how AM fungi simulating the growth and ameliorate citrus HLB infection in C. roseus under greenhouse conditions. During this process, various measurements were taken, and the agronomic characters, rate of colonization, infection intensity, arbuscular abundance, and HLB infection were analyzed. After C. roseus plants were inoculated with AM strains, strains GZ10, GZ5, and JX70 significantly enhanced the growth of C. roseus. Plants inoculated with GZ10 exhibited 23.1% and 12.1% increase in stem height and diameter, while GZ5 increased leaf number by 12.9%, both in respect to CK. Three strains (GZ1, BNMJ, and PWJ) improved disease resistance to citrus HLB, with a relative prevention rate of 78.39% for GZ1, 66.87% for BNMJ, and 69.75% for PWJ. The result proved that AM inoculation could significantly improve the growth of C. roseus and to some extent increase its disease resistance to citrus HLB.
