摘要: Chlorophyll content, photosystem 2 functioning (Fv/Fm, Fv/F0), activity of ribulose-1,5-bisphosphate carboxylase/oxygenase, and net photosynthetic rates (PN) flag leaf blade, sheath, peduncle, ear organs were assessed in large-ear type (Pin 7) small-ear (ND93) wheat cultivars. Some differences found properties between different green plant parts, the values all studied parameters parts being higher Pin7 than ND93. Furthermore, surface areas PN 26 genotypes measured at anthesis showed highly significant positive correlation with grain mass per ear. Hence a greater capability photosynthesis may result yield
