| 摘 要： | 采用磷脂脂肪酸(PLFAs)方法,分析同一果园台湾软枝杨桃(20年树龄)和荔枝乌叶品种(15年树龄)根区土壤微生物群落结构.结果表明,从杨桃根区不同样品检测到25 ～32种微生物PLFAs,特有PLFAs为:i13:0,11:0 3OH,14:0 2OH;荔枝根区检测到23～40种微生物PLFAs,特有PLFAs为:16:0 3OH,i18:0,i12:0,12:1 AT11-12,a14:0.杨桃根区由PLFAs指示的土壤微生物多样性指数(Simpson)和特征脂肪酸16:0(细菌)、18:1w9c(真菌)、10Me16:0(硫酸盐还原细菌)含量大小:距植株1.0m土壤≈1.5m土壤＞0.5m土壤；而荔枝根区Simpson指数和以上各种菌特征脂肪酸含量大小为:距植株1.0m土壤＞0.5m土壤≈1.5m土壤.脂肪酸10Me17:0(放线菌)和16:1w5c(甲烷氧化菌)含量在杨桃根区无水平分布上的显著差异,而在荔枝根区则存在显著差异. |

| Abstract: | The soil microbial communities in the root zones of Averrhoa carambola Linn.cv.Taiwan soft-branch carambola and Litchi chinensis Sonn.cv.Wuye,which had been growing for 20 and 15 years respectively in the same orchard,were analyzed using phospholipid fatty acids biomarkers(PLFAs).The result revealed that,all soil samples of the carambola plantation were detected 25-32 PLFAs biomarkers,with the distinctive as i13:0,11:0 3OH and 14:0 2OH.Soil samples of litchi plantation contained 23-40 PLFAs biomarkers,disti... |
