Abstract:

In order to investigate the effects of plant growth regulator B2 seed dressing and leaf spraying on the agronomic characteristics, photosynthetic characteristics, chlorophyll fluorescence parameters and yield of maize, the appropriate dose of B2 seed dressing and leaf spraying should be determined. Using Demeiya 1 as the material, the field-randomized block test method was used to set B2 seed dressing doses, including 0 (CK), 25 (BT1), 50 (BT2) and 100 (BT3) mg/kg, and the leaf spraying doses, including 0 (CK1), 25 (YT1), 50 (YT2), and 100 (YT3) mg/L. The results showed that B2 seed dressing and leaf spraying treatment, compared with CK and CK1, could reduce the plant height and ear height of maize, and increase the maize stem diameter, leaf area and dry matter accumulation and also increase the SPAD value and net photosynthetic rate (Pn), transpiration rate (Tr). B2 seed dressing and leaf spraying treatment could increase the actual quantum yield Y(Ⅱ), relative electron transfer efficiency (ETR), photochemical efficiency (Fv/Fm) and potential photochemical activity (Fv/Fo), and reduce the non-photochemical quenching coefficient (NPQ). Compared with CK and CK1, B2 seed dressing and leaf spraying treatment increased maize yield by 5.90%, 14.20%, 5.81% and 11.72%, 14.40%, 5.36% respectively. To sum up, when the seed dressing dose of B2 was 50mg/kg and the leaf spraying dose was 50mg/L, the yield of maize could be significantly increased.

Key words: Maize (Zea mays L.), B2, Photosynthesis, Chlorophyll fluorescence
