Abstract: To study the effect of different plant growth regulators on carnation growth and quality of flower, the combined application of DA-6, compound sodium nitrophenolate and fertilizer to carnation was carried out to find suitable kinds and concentrations of plant growth regulators. The results showed that 0.03 g/L compound sodium nitrophenolate and 0.03 g/L DA-6 could promote plant height, leaf number, leaf fresh weight, root weight and root length. 0.09 g/L compound sodium nitrophenolate could promote stem fresh weight and stem diameter. 0.03 g/L the compound sodium nitrophenolate could improve shoot diameter. 0.06 g/L DA-6 could enhance ornamental characters such as petal number, flower size, petal length and petal width of carnation compared with the control, and it could improve the quality of flower.
