Investigation of Root-knot Nematode in Five Oil-tea Species at Seedling Stage
摘要
Abstract
Root nematodes in five oil-tea species（Camellia oleifera,C.vietnamensis,C.nanyongensis,C.gigantocarapa,and C.polyodonta） were investigated at the stage of seedling in seedling nursery of Guangxi Forestry Research Institute.The results showed that all C.Oleifera had root-knot nematodes and the gall index was 53.8.The pathogen was identified as Meloidogyne incognita.The ratios of presence to absence of root-knot nematodes in C.nanyongensis,C.vietnamensis,C.nanyongensis and C.vietnamensis were 23%,18%,4% and 2% respectively.The gall index of C.nanyongensis,C.vietnamensis,C.nanyongensis and C.vietnamensis were 7.4,5.0,0.8 and 0.4 respectively.C.Oleifera had the most root nematodes,nanyongensis and C.vietnamensis had less,and C.polyodonta and C.gigantocarapa had the least.关键词
