Description:

Significant differences in net photosynthetic rate (PN) of leaves between two maize (Zea mays L.) strains (Shuang 105 and 40×44) grown in the field were observed. At several growth stages, PN of 40×44 was higher than that of Shuang 105 (from 10.3 to 32.5 %). Moreover, the strain 40×44 had a higher plant height, larger leaf area, lower chlorophyll content, and higher photochemical efficiency of photosystem 2 (PS2) (Fv/Fm and ΔF/Fm') than strain Shuang 105. Shuang 105, which showed lower PN, had lower stomatal conductances (gs) but slightly higher intercellular CO2 concentrations (Ci) than those of 40×44. Hence the differences in PN between the two strains did not result from the difference in gs, but probably from that in light reaction system. and Hua Jiang, Da-Quan Xu.
