  1. gFW, gram fresh weight; ND, not detected.
  2. The measurement is in pmol per gram gFW.
  3. Phytohormones were analysed by mass spectrometry. Means±s.e. from three independent experiments are shown. Asterisks indicate that contents of the compound were significantly increased (inc) or decreased (dec) compared with MG-20 (*P<0.05, **P<0.01, ***P<0.001; Student’s t-test).
