提高叶片光合作用是提高作物种子产量的一个诱人的方面。在大豆育种中利用野生近缘种是提高叶片光合作用的一个潜在来源。以大豆（Glycine max）和毛大豆（Glycine tomentella Hayata）回交后代为材料，测定了其气体交换、生物量和种子产量。从开花期到种子萌发期，测定了气体交换参数沿着变化的核酮糖-1，5-二磷酸羧化酶/加氧酶（Rubisco）含量和叶片氮含量（LNC）。结果表明，与德怀特相比，后代的净光合速率（Pn）、叶肉活性（Pn/Ci）、种子产量和地上总干重（TDW）均显著提高。后代比叶重（SLW）显著高于对照，且与净光合速率（Pn）呈显著正相关（r = 0.86*）。德怀特与后代的气孔导度（gs）无显著差异，但德怀特的胞间CO2浓度（Ci）高于后代。说明Pn的增加与Pn/Ci的提高有关。这些结果表明，大豆野生近缘种在育种中具有提高大豆叶片光合作用的潜力。
The enhancement of leaf photosynthesis is an enticing aspect for increasing crop seed yield. Using wild-related species in soybean breeding can be a potential source to enhance leaf photosynthesis. Two backcross-derived progenies of soybean (Glycine max) withGlycine tomentellaHayata were evaluated in terms of gas exchange, biomass, and seed yield. The gas exchange parameters along with Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) content, and leaf nitrogen content (LNC) were measured from flowering stage up to seed initiation stage. Results revealed significant increases ofnet photosynthetic rate (Pn), mesophyll activity(Pn/Ci), seed yield, and total aboveground dry weight (TDW) in progenies relative to Dwight. We observed significantly higher specific leaf weight (SLW) in progenies and was strongly correlated withPn(r = 0.86***). There was no significant difference between Dwight and the progenies instomatal conductance(gs), but Dwight, in fact, had higherintercellular CO2concentrations(Ci). It indicates that increases inPnwere associated with improvedPn/Ci. These findings suggest the potential use of soybean wild relatives in breeding to enhance soybean leaf photosynthesis.
