Effects of the interaction between seeding rate and nitrogen rate on Rubisco and RCA activities at different leaf positions of the rice population 10 days after flowering under dry cultivation. (a) Rubisco activity in the flag leaf, first second leaf, and first third leaf. (b) RCA activity of the flag leaf, first second leaf, and first third leaf. Different letters with the same sowing amount indicate a significant difference at P < 0.05. The figures were prepared and combined using Origin 2018 (www.originlab.com).
