摘要: The aim of this work was to investigate development of some photosynthetic characters and their relationship with seed yield during the genetic improvement of soybean. For this objective, we grew 38 soybean cultivars representing genetic improvement progress in northeast China, released from the period of 1923 to 2005 (82 years). The experiment was performed in 2005 and 2006. Some photosynthetic characteristics such as leaf area, chlorophyll content and specific leaf weight (SLW) were measured at R2 stage (flowering …
