摘　　要：为了探明淀粉加工型甘薯品种苏薯11号的高产生理特性,对该品种的群体生长特征及个体发育特点进行了动态比较研究。以淀粉加工型甘薯品种苏薯11号为材料,苏渝303和南薯88作对照,动态比较分析了其高产生理特性。研究显示苏薯11号具有栽后地上部早生快发,前期茎叶生长快并形成较多分枝,中期比较平稳,后期下降缓慢;地下部结薯早,薯块膨大早且保持较高增长速率和较长的持续时间。群体结构保持较高的相对生长率、叶面积指数和净同化率也是其获得高产的重要保证。苏薯11号具有"源"强、"库"大、"流"畅的特点,这些群体生理特性为其高产栽培奠定了重要基础。In order to study the physiological characteristics of highly yield on"Sushu 11",a variety of high yield and starchprocessing.A comparative analysis on population structure and individual characteristics of growth of"Sushu 11"were carried out in 2008.Physiological characteristics of Highly Yield were analyzed using"Sushu11"for starch-processing variety,"Suyu303"and"Nanshu 88"as check.The result showed:Faster reviving after transplanting,stems and leaves develop fast with many branches taking shape in earlie...
