| 摘 要： | 采用田间对比试验,从甘薯的生长发育动态及T/R值变化动态、净同化率和干物质的积累与分配等方面,对冀薯98的生长发育特性进行了研究.结果表明:冀薯98前期茎叶生长较快,光合叶面积大,中后期生长平稳;块根膨大快、持续时间长;T/R值比例合理,净同化率高,同化物运转速率快.

| Abstract: | By studying the development of a new sweet potato cultivar Jishu 98,we got the result that the cultivar has the following characteristics: the leaf and stem have a higher growing speed in early period,larger photosynthesis area,and during the midterm and late growing period it keeps steady growing speed,with high speed and long time of earthnut swell,appropriate T/R rate,high assimilation rate,and higher speed of assimilation production transfer. |
