CR2002 showed delayed senescence under dark-induced senescence (DIS) conditions. Hwaseong and CR2002 were grown in a paddy field, and fully expanded flag leaves at the heading stage were used for DIS. (a) Detached leaves were incubated in 3 mM MES buffer (pH 5.8) at 27 °C under dark conditions. (b,c) Total chlorophyll contents (n= 6) and Fv/Fm ratio (n= 5) were compared between Hwaseong and CR2002. Error bars indicate a standard error, and more than three samples were used for each experiment. * and *** indicate significant difference at p < 0.05 and p < 0.001 based on Student’s t-test, respectively.
