Fig. 1

Effect of heat stress on the spikelet fertility of rice plants at the flowering stage. a, b, d and e show rice plants with spikelets exposed to heat stress for 10 d at flowering stage. c and f show the response of spikelet fertility to heat stress at different flowering time period. HAF is hours after flowering. 0–2 HAF, means that the flowering spikelets were immediately subjected to heat stress for 2 h; 2–4 HAF, means that rice plants were subjected in heat stress for 2 h during 2–4 h after flowering. g shows the effect of NAA and AOPP on the spikelet fertility of rice plants under heat stress at the flowering stage. Different NAA and AOPP levels were sprayed onto the flowering spikelets before heat stress. Different letters within the same column indicate statistically significant differences between different treatments in the same cultivar (n = 3) (P < 0.05)
