苎麻高产优质新品系R057新麻生长发育特性研究

以湖南主要推广品种湘苎三号、Tri-1等为对照,对苎麻新品系R057新麻的生长发育特性进行了研究.结果表明,1)R057地下部分生长发育具有优势,其根系体积、萝卜根和龙头根数量均优于对照;2)新品系R057具有较强的分株力,高达28株/m~2,明显高于对照;生长速度前期较快,黑脚期后生长基本停止;3) R057单株叶片数和叶面积与对照无明显差异.

Studies on the characteristics of growth and development ramie line R057 newly planted

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.
