Extended Data Fig. 9: The effect of low temperature and its duration on the regrowth of perennial rice.
From: Sustained productivity and agronomic potential of perennial rice

a, The relationship between regrowth rate of PR23 and average monthly temperature in January. The data were derived from Yuanjiang, Jinghong, Lancang, Wenshan, Simao, Yiliang, Baoshan, Yudu, Congjiang, Guizhou, Shangsi and Guanyang locations in 2016–2017. The regrowth rate of perennial rice had a significant quadratic correlation with average monthly temperature of January 2017 (R2 = 0.73*, P < 0.05). b, The effect of low temperature and its duration on regrowth rate of PR23. D3, D5 and D7 referred to the duration of low temperature condition for 3, 5 and 7 days, respectively. The error bar represents the standard error of each treatment. The data are means from Experiment 5, with l.s.d. for regrowth of a) 25.7 (N = 48) and b) 3.2 (N = 18) respectively (P < 0.05) (see Supplementary Tables 10 and 11).
