Abstract
Effects of different concentration of plant growth regulators on seed germination of Senecio cineraria were studied such as GA3,NAA and 6-BA.The results showed that GA3,NAA and 6-BA had obvious promotion functions on seed germination not only in improving germination energy and germination rate,but also in shortening germination process.High concentration inhibited seed germination.The optimum concentration was GA3 1mg/L,NAA 5mg/L and 6-BA 0.1mg/L,respectively.And the germination energy of them was 19.00 %,10.33 % and 7.33 % higher than that of control group.The germination rate was15.34 %,6.34 % and 7.67 % higher,respectively.
