摘　　要：以雌性苎麻GBN09与雌雄异花同株苎麻GBN08为材料,比较分析它们的植物学性状、农艺性状、叶绿素含量和碳、氮含量,结果表明:GBN08的株高、有效株率、出麻率和产量均高于GBN09,茎粗低于GBN09;GBN08的叶绿素含量和叶片C/N值大于GBN09,但花蕾的C/N值小于GBN09;GBN08雄花(蕾)的C/N值大于雌花(蕾)。In this paper,the botany character,agronomical character,chlorophyll,carbon and nitrogen content were compared and analyzed in female ramie GBN09 and hermaphrodite ramie GBN08.The result showed that the plant height,percentage of effective plant,percentage of bast fiber and yield in GBN08 were higher than those of GBN09,but stem diameter was lower than that of GBN09.The content of chlorophyll in GBN08 was higher than that of GBN09.C/N of the leaves in GBN09 was lower than C/N in GBN08.While C/N in male and female flower of GBN08 was lower than female flower of GBN09.
