2、芒284号、台农1号、帕拉英达芒、水英达芒、金煌芒、肯特芒和紫花芒等9个占占种.对9个品种的株高、冠幅、茎围、开花率和产量等述行比较分析。【结果】桂热芒284号株高和冠幅均最大,分别为362.7啪和354rocm,显著大于肯特芒和挂热芒302号,开花率和产量中等,分别为753%和179735kgma,均显著低于产量最高的占特芒;幢热芒71号平均产量222354k∥ha,其株高、冠幅、茎围、开花率和产量与垒煌芒相当,产量极显著高于最低,的台农l号,具有树澎矮化、树姿开张、开花率中等、产量高等优点。【结论】桂热芒284号袁现植株生长快.开花坐果率
3、良好、产量稳定,桂热芒7l号表现植株矮化、树势开张、开花和坐果率良好、产量高等优点,这两个品种可进步进行生产性试验;帕拉荚达芒、桂热芒302号两个品种的产量一般,可保留作进一步观察;水英达芒、台农1号两个晶种产量较低,不宜在南宁地区发展种植。关键词:芒果;品种比较;生长量;产量中圈分类号:s667.7文献标志码:A立章编号:20951191(2012)07—1010—03ComparativetestonnewmangovarietiesLIRi-wang,HUANGGuo—di,ZHOUJun—an,CHENYong—sen,MOYong—
