  1. GP germination percentage, Dif. difference of t75 or t~50, highlighted in italic characters, vmax modelled maximum deterioration rate, #MP75 was the multiple of the average deterioration rate which is reciprocal of t75 (the timespan to deteriorate to GP≈75%), of NPB-11M, 17M and 6M-S1 respectively to reduce to 75% viability against the comparative average rate of NPB-6M, e.g. MP75 for “17M vs 6M” was 1/4 ÷ 1/12 = 3. Similarly, MPvmax was the multple of vmax, e.g. MPvmax for “11M vs 6M” was 10.61 ÷ 13.15 = 0.81. MP75 and MPvmax values were given in bold.
