| Abstract: | Using main ramie varieties in Hunan as the check varieties,a the comprehensive analysis about young ramie of the new variety R057 was conducted.The studies showed that,1) The new strain R057 is of superiority to the check varieties in the growth of subterranean stem,the volume of root system,the quantity of radish root and main item root.2) In new strain R057,the population density reached 28/m2,higher than that of check varieties,which indicaed its the higher power of division.The new strain R057 grows quick in the early stage,but tended to stop the black foot stage.3) The new strain R057 shows no difference or superiority in the number and area in of the leaf single plant. |
| Keywords: | ramie new strain R057 growth regularity |
