  1. NP no priming, NPB-6M simply under 6 months room-temperature-storage as the control, H100, S1, HP priming with 100 mM hydrogen peroxide, 1 mM spermidine and distilled water respectively.
  2. ROS level and membrane permeability level were determined by the intensity of staining by NBT and FM4-64 respectively. Different letters indicated that the levels were significantly different with P < 0.05 (extremely significantly with P < 0.01 for letters within the brackets).
  3. *Membrane permeability of NPB-H100 was significantly greater than NP with P < 0.01.
