摘要

摘要: 通过病害症状观察、分离菌致病性测定, 以及分离菌株的形态和培养性状观察、rDNA-ITS序列分析将从莲雾果实上分离到的菌株FJAT-9860鉴定为可可毛色二孢菌Lasiodiplodia theobromae。菌株FJAT-9860在PDA培养基上菌落最初为白色, 后逐渐变为灰色到黑色。分生孢子为单细胞, 无色透明, 椭圆形至圆形。ITS序列分析表明, 菌株FJAT-9860与Lasiodiplodia theobromae strain亲缘关系最近, 同源性为99%。该菌株最适生长温度为25℃, 最适生长pH值为8.0, 不同碳源对菌株FJAT-9860的生长影响不同, 最佳碳源为甘露醇。

Abstract: In order to identify the causal agent of black spot disease on wax apple (Syzygium samarangense Merr.et Perry) in its taxonomic status, the causal fungi FJAT-9860 was isolated and characterized with pathogenicity test, morphology and culture feature observation, rDNA-ITS sequences assay and biological characteristics test.The results indicated that the causal agent belong to Lasiodiplodia theobromae.The colony of strain FJAT-9860 on PDA was white at first, then gradually became as grey to black.The monadic conidia were elliptic to round, and colourless.The rDNA-ITS sequence of the strain shared 99%identity with that of Lasiodiplodia theobromae strain.The results showed that the optimum temperature for mycelium growth of this pathogen was 25℃and the optimum pH was 8.0.The mycelial growth was affected by different carbon sources and the best one was mannitol.
