High yield mechanism and physiological characters of new sweetpotato varieties

摘要：

By studying on development of new sweetpotato varieties Jishu 98 and Jishu71,we got the resuit that high yield varieties have the following common characters：the leaf and stem have a rapid growth in early period,large photosynthesis area；and during the midterm/middle and late growth period they keep steady growing speed；with high speed and long time of earthnut swell,appropriate T/R rate,high assimilation rate,with high speed of assimilation production transfer.In a word,they are high photosynthetic efficiency varieties.
