Figure 2.

(A) The germination rate of NIP and pnfyc lines under different concentrations of exogenous hormones. (B) The plant morphology of NIP and pnfyc lines treated with different exogenous hormones at 7 days after germination. (C) The seedling height of NIP and pnfyc lines under different exogenous hormones at 7 days after germination. Bar = 1 cm. (D) The relative germination of the NIP and pnfyc seeds under ABA treatments were determined after 4 days and expressed as a percentage of those grown under ‘mock’ conditions. (E) Quantification of GA3 derivatives in NIP and pnfyc seeds germinated for 6 h was analyzed with liquid chromatography-tandem mass spectrometry. Data are shown as means ± SD of at least three biological replicates. (** p < 0.01 by two-tailed Student’s t-test).
